Always faster, always better –
from initial concept to series production
STREAMLINED PRODUCTION CYCLES
Every business strives to perform faster
and better, but this is especially critical
in the rapidly changing automotive world.
Smart response
If required, we can deliver installationready gaskets directly to your assembly line – based solely on the engine's
design data. Our design system is compatible with your in-house CAD system,
whether it’s CATIA, ProEngineer, IDEAS,
or Unigraphics.
Time and again, our customers are
surprised by the short lead times at
VICTOR REINZ. We do this by employing all necessary experts in-house,
from development to series production.
As a result, handling times are greatly
reduced. In addition, we can perform
all the important validation tests on-site
with our own equipment.
Smart combinations
Ingenious matching of conventional development tools to each other can result
in significant time savings.
One example: At VICTOR REINZ we not
only test and simulate entire sealing
systems with computers – we also use
modern prototyping procedures to build
functional models at a very early stage.
When testing the specific sealing functions, these prototypes supply extremely valuable data. This enables us to
determine in advance whether a gasket’s performance is maximized, so that
individual functions don’t require optimization later.
Nonetheless: Even something good
can be improved
Since approximately 70 percent of an
automobile’s components come from
external suppliers, the quality of a vehicle depends greatly on the quality of
the supplied products. Because quality
cannot be improved later, we understand
that intelligent product design, exact
planning, and compatible engineering
from the start will ensure quality assurance in product development and
manufacturing.
ISO/TS 16949: Our quality standards include DIN EN ISO 9001,
VDA 6.1 and EAQF 94 as well as specific customer requirements from GM, DaimlerChrysler, and all German auto makers.

STEPS TO OPTIMUM PRODUCT DESIGN
Transforming vision into reality
Our project teams consist of application
engineers who work with developers,
designers, manufacturing and quality
experts, logistics specialists, and buyers
to find the best solution.
In this way, the expertise of each participant is taken into account from the
beginning. This close collaboration exemplifies the value we place on our relationship with our customers.

Responsibility from beginning to end
PROACTIVE DEVELOPMENT PARTNERSHIP YOU CAN TRUST
We look forward to being your partner throughout the design
and production process, and welcome open dialogue at any
time – whether it’s contract development or purposeful, objective product consultation. The scope of VICTOR REINZ expertise covers all aspects from development to logistics.
Here are a few examples:
Assessment of
requirements
Assessment of
requirements:
The earlier the better
Every gasket involves many specific
functions, so it pays to consult with us
early. Frequently, the object is not only
to provide sealing from different media,
but also to minimize component deformation. If all functional requirements
are considered from the beginning, complications and loss of time are greatly
reduced during subsequent project
stages.
This attention to detail begins right
away, during your first consultation
with our application and development
engineers. Design procedures are
straightforward. We require just a few
parameters: Operating temperature,
internal pressure, dynamic behavior,
number of fixing screws, plus a few
details on the materials used for the
surrounding components, their surface
finish, and their geometry.
That's it – our engineers determine
the rest.

Design & construction:
Built to fit
Calculation
Design & construction
While vehicles are not built around the
gaskets, they are still critical components. Attention to product design combined with high-quality materials is the
best foundation for functional, reliable,
high-quality gaskets.
Thinking ahead is part of going the extra
mile for customer at VICTOR REINZ.
During the gasket’s design phase, we
simulate the automated assembly sequence in the production line or during
servicing, and also consider the packaging aspects. Even recycling issues
and clean separation of the materials
used is factored in.
Interfaces:
“Built-in” understanding
Finite Elements Analysis
(FEA): Working smarter
from the start
Ever more often, increasingly complex
designs are required for metal gaskets.
Whether in the exhaust train, in turbochargers, or special gaskets for highpressure diesel fuel pumps – suitable
sealing is ensured by half beads, full
beads, and the patented Wave-Stopper®.
Not an easy task. If requested by the
customer, we conduct FEA calculations
of the entire sealing system, i.e. the
gasket and the components to be sealed.
The advantage: During FEA calculations early in the design phase, all relevant functional parts and critical areas
of the entire sealing system are examined in detail to ensure optimum gasket development in the shortest time.
Moreover, FEA calculations supply valuable details on component stiffness,
distortion, and pressure distribution.
Prototyping
Take metal gaskets, for example: We
use close-to-production tooling from the
start. After the sheets have been coated
on series production plant, and the gasket contour has been cut with lasers,
even the most complex beads can be
stamped with our embossing tools. Of
course, all these tools are produced on
our premises quickly and cost-effectively. Your advantage: Prototypes are of the
same quality as the later series gaskets
– with few deviations. Modern CNC-controlled measurement equipment ensures
optimum quality monitoring.
Subsequently, all relevant data are recorded in a technical document.

In addition, through Dana Sealing Products and its four development centers
in Neu-Ulm, North America, Japan, and
Brazil, we have worldwide access to 27
engine test stands and associated laboratories for analysis and static/dynamic
pre-testing.
All activities are coordinated by the
Competence Center R & D in Neu-Ulm,
to ensure your testing benefits from the
most advanced technology »Made in
Europe«.
Laboratory tests (excerpt)
¬ RPM 1) 510-3D: The setting behaviour (creep resistance) of a gasket is
determined as a function of surface
pressure and temperature. The resulting (derivable) loss of bolt load is
decisive for the sealing behaviour.
¬ RPM 1) 511-S: The distribution of
surface pressure on the surrounding
components is determined by means
of a computer-controlled hydraulic
test stand. With metal gaskets, for
example, a test program with repeated loading/unloading cycles is used
to determine the bead characteristics, which are then compared with
the calculated FEA values from the
simulation.
¬ RPM 1) 528: By means of resonance
pulsers and simulators, various operating conditions (temperature, pressure, dynamics) are simulated, and
conclusions are drawn about the gasket's durability.
¬ RPM 1) 535: Determines a gasket's
sealing potential, depending on the
component's surface roughness, its
flatness, and the bolt force. Seal
tightness is tested with nitrogen or
with liquid media such as engine oil
or antifreeze.
¬ RPM 1) 550: By means of a pressuresensitive film (Fuji film), the distribution of surface pressure over the
gasket is determined, scanned, and
evaluated electronically.
Of course, we conduct any additional
laboratory tests requested by the customer. These range from investigating
the media resistance of the material
used, through porosity, roughness, and
evenness tests of the sealed components, up to special examinations of
residual particles, e.g. if gaskets for
dust-sensitive components such as
high-pressure injection pumps are to
be packaged under cleanroom conditions.

Sealing systems for the entire power train –
everything else is secondary
ABOUT TRENDS
Trends apply for almost everything.
For automobiles just as for the components used to build them – and for
gaskets, of course. Hereby, the trend
is clearly toward pure metal and coated metal gaskets. Apart from the functionality, durability, and maintenance
freedom of these gaskets, another major
reason for this trend is the suitability
for automated assembly, i.e. simple
handling with robots and automatic
manipulators. Naturally, this doesn't
mean that VICTOR REINZ does not offer
fiber composite as an alternative.
Because they remain to be essential
for many applications.
Make sure its VICTOR REINZ
VICTOR REINZ recognizes these demands at an early stage, and responds
to trends with new products. Regardless of the equipment that needs a
gasket – we always have more than
one good solution in stock.
Why you should play it safe
A growing number of automotive manufacturers are placing their trust in
VICTOR REINZ sealing systems. In
addition to meeting all of the above
demands, our gasket materials and
sealing concepts are so reliable that
they perform their tasks throughout
the vehicle’s lifespan. We help you
build better automobiles.
More engine output, higher packing densities, tougher environmental legislation. Sealing systems from VICTOR REINZ
ensure better performance. Regardless of the working conditions.

Gasket selection
With VICTOR REINZ, selection of a suitable sealing concept is really simple.
We require just a few parameters:
Surface texture of the
surrounding components
One important basic requirement for
optimum sealing is the surface texture
of the components to be sealed. Surface
texture is determined according to DIN
EN ISO 4287 and DIN EN ISO 4288 using
the profile method to generate an envelope profile from which the following
values are defined:

Beaded metal gaskets with elastomer coating
PROGRESSION® CS AND PROGRESSION® CS PLUS – STANDARD SOLUTION FOR AN ATTRACTIVE PRICE
Material
PROGRESSION® CS and PROGRESSION®
CS plus are metal gaskets with an elastomer coating on both sides. Moreover,
both sides of the gasket material have
a non-stick surface.
PROGRESSION® CS has a core of 0.25 mm
thick steel sheet, coated on both sides
with a 65 µm layer of nitrile rubber
(NBR). PROGRESSION® CS plus differs
in that its core is of 0.2 mm thick stainless spring steel (material 1.4310) with
a 75 µm layer of NBR on both sides.
PROGRESSION® CS and PROGRESSION®
CS plus gaskets are always beaded.
Therefore, these gasket materials provide perfect solutions e.g. for intake
manifolds and areas subjected to high
mechanical and/or thermal loads, as
well as particularly narrow sealing faces
with low surface pressures. Other typical applications are oil pans, transmission flanges, housings, and pumps.
Properties
Apart from excellent conformability to
uneven sealing surfaces, PROGRESSION®
CS and PROGRESSION® CS plus ensure
outstanding sealing against liquids and
gases. Both gasket materials are resistant against oils, fuels, antifreeze, refrigerants, and biologically degradable
lubricants.
PROGRESSION® CS plus exhibits much
higher elasticity and recovery than
PROGRESSION® CS, and even better
mechanical strength and corrosion resistance.
Application example
For stable systems with low bolt forces
and low thermal expansion, PROGRESSION® CS offers an attractive price/performance ratio, e.g. as a flange gasket
on the engine intake side.
PROGRESSION® CS plus is intended
primarily for systems with high dynamic
loading and high alternating pressures
up to 120 bar, e.g. in the power steering pump.
Application areas
PROGRESSION® CS is the standard solution for static applications with medium bead loads, whilst PROGRESSION®
CS plus is intended for highly dynamic
applications with high bead loads. Both
materials are suitable for working temperatures up to 200 °C.
Trend
PROGRESSION® CS and PROGRESSION®
CS plus are the answer to increasing
pressures and dynamics in modern,
high-performance engines. Both gasket
materials offer numerous possibilities
for integration, and have sufficient reserves for future sealing concepts.

PROGRESSION ® CA – LIGHTWEIGHT WITH A BRIGHT FUTURE
Application areas
PROGRESSION® CA is the preferred gasket material for all lightweight components, and temperatures up to 120 ºC.
Its special advantages become apparent
when used with Al and Mg flanges, as
there is no corrosion.
Material
PROGRESSION® CA is a metal (aluminium) gasket material, with an elastomer
coating on both sides. Moreover, both
sides of the material have a non-stick
surface. PROGRESSION® CA has a core
of 0.20 mm thick aluminium sheet
(Al/Mg alloy), coated on both sides with
a 75 µm layer of nitrile rubber (NBR).
Normally, PROGRESSION® CA is beaded.
Properties
PROGRESSION® CA has outstanding specific properties: Low weight, high thermal conductivity, excellent corrosion resistance. Particularly when used to seal
aluminium components, the identical
thermal expansion coefficient is of decisive importance.
Due to its unique combination of aluminium, elastomer, and beads, PROGRESSION® CA offers all the features
required for good conformability to
uneven surfaces, high sealing integrity
with liquids and gases, high elasticity of
the installed gasket (recovery), plus
good media resistance.
Application example
The high performance potential of PROGRESSION® CA is not only due to the
materials used. Especially because of
low surface pressures and occasional
high values of surface roughness, this
gasket material is used e.g. in charge
air dampers and other mechanical compressors.
Trend
The trend toward lightweight construction
will increase. Engines and individual components of aluminium or magnesium are
determining factors in automotive engineering. PROGRESSION® CA effectively
supports this development. Also in future.

RETALL ® FPM PLUS – TEMPERATURE & MEDIA UNDER CONTROL
Application areas
RETALL® FPM plus is used for sealed
joints that place high demands on mechanical and thermal loading. These
include EGR, intake manifold, engine
ancillaries, and valves.
Material
RETALL® FPM plus consists of a sheet
steel core that is coated on both sides
with a high-quality elastomer. Moreover, both sides of the gasket material
have a non-stick surface. RETALL® FPM
plus has a core of stainless spring steel
(type 1.4310), and a thin elastomer
coating of fluorine rubber (FPM). The
gaskets are always beaded.
Properties
The special coating of RETALL® FPM plus
is a guaranteed combination of high
temperature resistance up to 280 °C,
and excellent media resistance. Other
features are outstanding conformability
to uneven surfaces, very high sealing
integrity with liquids and gases, high
elasticity of the installed gasket (recovery), plus mechanical strength. All of
these sealing properties are due to the
combination of an elastomer-coated
metal core and beads.
Application example
Thanks to its high temperature resistance, RETALL® FPM plus is the preferred
material for valve gaskets in exhaust
gas recirculation (EGR) systems. The
gaskets are fitted with clamping claws,
e.g. for clipping them to oval flanges.
Screw retainers greatly simplify overhead installation.
Trend
The demand for environmentally compatible engines with optimized emission values leads to increasingly high
operating temperatures for EGR systems. RETALL® FPM plus is a gasket
material that has been designed specifically for the demands placed by
EGR systems.

RETALL ® F51 AND RETALL ® F52 – OPTIMUM SEALING WITH PARTIAL COATING
used e.g. in high-pressure fuel pumps,
where peak pressures in excess of
2400 bar are possible, whilst RETALL®
F52 is used e.g. in the control modules
for automatic transmissions.
Material
RETALL® F51 and RETALL® F52 are metal gasket materials, which have been
partially coated with fluorine rubber
(FPM) using the screen-printing process.
RETALL® F51 has a core of corrosionproof stainless steel (type 1.4310), whilst
with RETALL® F52 it is made of carbon
steel or aluminium.
RETALL® F51 gaskets are always beaded.
Properties
The partial coating of RETALL® F51 guarantees extremely low setting behaviour,
e.g. in the vicinity of the head bolts, and
reliable clamping conditions. RETALL®
F51 has good conformability, high elasticity, very good sealing integrity with
liquids and gases, plus outstanding
thermal resistance up to 240 °C continuous temperature.
RETALL® F52 also has good conformability, excellent creep resistance, is resistant to automatic transmission fluids
(ATF), and temperature resistant up to
240 °C.
Thanks to possible coating thicknesses
up to 500 µm, component distortions
can be optimally compensated.
Application areas
RETALL® F51 and RETALL® F52 offer
all the features required for demanding
special solutions. In combination with
special bead designs, RETALL® F51 is
Application example
The combination of pulsating internal
pressures, low bolt clamping forces,
and wide bolt spacing is a challenge
for every gasket. Thanks to the pronounced plastic-elastic behavior of the
partial coating, RETALL® F52 is the ideal
sealing concept for automatic transmission control modules, as it provides
optimum compensation of component
distortions.
Trend
When it comes to contamination from
particles or dust, high demands are
placed on precision components such
as high-pressure fuel pumps. VICTOR
REINZ was the first gasket manufacturer to introduce automatic cleaning &
packaging processes for gaskets, thus
meeting customer demands in terms
of cleanliness.

Beaded metal gaskets with fiber-reinforced elastomer coating
MATRICS ® AND MATRICS ® PLUS – PERFECT CONFORMABILITY
Material
Matrix Coated Steel – MatriCS® for short
– is the unique combination of a sheet
steel core and a fiber-reinforced elastomer coating. MatriCS® has a carbon
steel core, whilst MatriCS® plus uses
stainless steel. A coating of fiber-reinforced, temperature-resistant elastomer
is rolled onto both sides of the sheet
core. Hereby, a primer layer ensures a
perfect and durable rubber-metal bond,
and a non-stick gasket surface guarantees optimum disassembly properties.
MatriCS® consists of a 0.25 mm thick
steel sheet, coated on both sides with
a 0.125 mm layer of high-quality, fiberreinforced nitrile rubber (NBR).
MatriCS® plus differs from MatriCS® in
that the core material is 0.2 mm stainless spring steel (type 1.4310) with a
slightly thicker elastomer coating of
0.15 mm.
Properties
MatriCS® and MatriCS® plus combine
mechanical strength and outstanding
creep resistance with high compressibility and excellent recovery. MatriCS®
and MatriCS® plus stand for high temperature and media resistance, in
particular with regard to mineral and
synthetic oils, fuels, antifreeze, and refrigerants.
With its stainless steel core, MatriCS®
plus offers additional advantages. The
gasket is corrosion-proof, has an even
longer service life, and due to its even
better recoverability, it features optimized dynamic behavior.
Application areas
MatriCS® and MatriCS® plus are designed to withstand high mechanical
and thermal loads. Therefore, these
gasket materials provide universal
sealing solutions for engines, engine
ancillaries, and for drivetrains.
MatriCS® is the standard answer for
rough sealing surfaces, whilst MatriCS®
plus sets new standards in the damping of component dynamics. Typical
applications for MatriCS® are intake
manifolds, oil pans, EGR systems, and
gearbox covers; for MatriCS® plus they
include timing chain covers, oil pans,
and water pumps.
Application example
The strengths of MatriCS® and MatriCS®
plus come to bear especially with flexurally weak components that exhibit
low sealing pressures and poor pressure
distribution. With gearbox covers, for
example, beaded gaskets provide highly reliable and durable sealing even
with low bolt forces and rough sealing
faces.
Trend
Lightweight construction and downsizing concepts require increasingly wide
bolt spacing and higher temperatures.
MatriCS® and MatriCS® plus boost the
performance potential of elastomercoated metal gaskets by means of
significantly improved conformability,
and low setting at high temperatures.

Beaded metal gaskets – now up to 1100 °C
RETALL ® HRS AND RETALL ® HTS – LESS CAN BE MORE
results are obtained at working temperatures up to 650 ºC, and up to 950 ºC
with RETALL® HTS.
Material
RETALL® HRS and RETALL® HTS are
purely metal gasket materials with one
or more layers, made of stainless spring
steel or stainless high-temperature
steel. With multilayer versions, the individual layers are spot-welded and,
depending on the application, they are
beaded.
Application areas
The application areas of RETALL® HRS
and RETALL® HTS depend on the specific requirements. RETALL® HRS is the
best choice for working temperatures
up to 650 ºC and high demands on
elasticity, whilst RETALL® HTS is ideal
for working temperatures up to 950 ºC
but with lower demands on recovery.
Both material types are used mainly
for exhaust manifolds, turbochargers,
EGR flanges, diesel particle filters, and
catalytic converters.
Especially for series production, RETALL®
HRS and RETALL® HTS are the standard
solution for exhaust system applications.
Properties
RETALL® HRS and RETALL® HTS exhibit
high temperature resistance and high
durability. With RETALL® HRS, the best
Application example
RETALL® HRS is preferably used for
two-layer exhaust manifold gaskets.
Special designs with beads and stop-
pers ensure good recovery, as required
by high component dynamics as well
as occasional extreme thermal expansion. Stoppers relieve the beads so that
they are not fully compressed, and the
defined working range is maintained.
The stopper serves as a pre-sealing
element and reduces the dynamics at
the component surfaces.
For applications on and around the turbocharger, the strengths of RETALL®
HTS play a decisive role. The material's
high temperature resistance sets new
standards in this area.
Trend
High dynamics and temperature stresses with increasing exhaust gas back
pressures – these requirement specifications for modern turbocharged engines are met by gaskets made with
RETALL® HRS and RETALL® HTS.
Tip!
For applications with extreme operating conditions, the new RETALL®
HRTS with a high-temperature steel
core can be used. This gasket material withstands temperatures up to
1100 °C, whilst exhibiting good recovery behaviour.

THERMO-GLIDE ® – PERFECTLY TIGHT IN SPITE OF HIGH DYNAMICS AND TEMPERATURES
Application areas
thermo-glide® is particularly suitable
for sealed joints that must provide good
micro-sealing under high dynamic and
thermal loading. Main application areas
are for components subjected to different thermal expansion rates: e.g. exhaust manifold gaskets, turbocharger
gaskets, highly stressed gaskets for
EGR systems, and other gaskets in the
exhaust train.
Material
thermo-glide® is a powder-coated layer
of lubricating lacquer for metal gaskets. The combination of high-temperature-resistant resins and special organic lubricant materials is used to
increase the potential of RETALL® HRS
and RETALL® HTS.
Normally, thermo-glide® is applied to
the gasket surface that is exposed to
the hotter and/or rougher side of the
sealed joint.
Properties
The high-temperature-resistant thermoglide® coating reduces friction and
improves the gasket's conformability
to micro-roughnesses. This ensures
considerably better sealing integrity.
thermo-glide® resists temperatures up
to 1000 °C.
Thanks to the simultaneous use of several wear and friction-reducing lubricants, thermo-glide® exhibits optimal
slip characteristics in a wide temperature range. It provides lasting protection
from surface damage due to cold welding, as the frictional wear of the gasket
and component surfaces under thermal
and dynamic loading is significantly
reduced.
Application example
Modern exhaust manifold gaskets between cylinder head and manifold must
provide perfect sealing in spite of high
temperature variations and frictional
movement. Even during cold tests,
thermo-glide® has very low leakage
values, and in its role as a problemsolving layer, it prevents damage to the
beads caused by frictional movement.
Trend
Increasingly tough emission regulations
place new demands on the sealing integrity of the entire exhaust train. Already today, special bead technology in
combination with thermo-glide® ensures
the compliance with future emission
legislation involving reduced leakage
rates for lower exhaust gas emissions.

Metal/rubber gaskets
FPM 70 – INCLUDING FLEXIBLE MEDIA AND TEMPERATURE RESISTANCE
Material
FPM 70 consists of a metal core with
molded-on FPM elastomer profiles. The
core is made of stainless steel (e.g.
type 1.4303) or galvanized carbon steel.
Media-resistant fluorine rubber with a
hardness of 70 Shore A is used as
elastomer.
Hereby, the fluorine rubber can be surface molded, edge molded, or backbone
molded. The elastomer elements are
always used with controlled compression, whereby travel limiting is ensured
e.g. by means of a groove in the component.
Properties
Regarding media resistance, FPM 70 is
an outstanding combination providing
resistance to fuels, water/antifreeze,
and lubricating oil. The gasket material
is designed for a wide temperature
range from -24 °C up to +230 °C.
Other positive features are low setting
and bolt load loss (also in case of wide
bolt spacing), low clamping force requirements for high sealing potential,
plus high elasticity and durability.
Application areas
FPM 70 is particularly suitable for simultaneous sealing of different media
from each other, e.g. in oil filter cooling modules. Other application areas
are sealed joints in the intake duct,
the throttle flap, or in transmissions.
Application example
The edge-molded version of FPM 70
permits the oil and water channels in
oil filter cooling modules to be sealed
in a simple manner. For applications
previously requiring the use of different elastomer materials, FPM 70 is
today's answer. Hereby, the fluorine
rubber molded onto the metal core
adapts to component distortions without overpressing.
Trend
Gaskets with a large surface also need
to be manufactured cost-effectively in
small quantities. Alternatives to onepiece gaskets are inserts of FPM 70
around coolant or oil channels, which
are laser-welded onto the gasket.

ACM 50 AND ACM 60 – THE COST-EFFECTIVE STANDARD SOLUTION
Material
ACM 50 and ACM 60 consist of a metal
core with molded-on ACM elastomer
profiles. The core is made of stainless
steel (e.g. type 1.4303) or galvanized
carbon steel. Acrylic rubbers with a
hardness of 50 Shore A or 60 Shore A
are used as elastomer.
Hereby, the acrylic rubber can be surface molded, edge molded, or backbone
molded. The elastomer elements are
always used as force shunts, whereby
travel limiting is ensured e.g. by means
of a groove in the component.
Properties
ACM 50 and ACM 60 are characterized
by very good resistance against oil in a
wide temperature range between -30 °C
and +150 °C. Other positive features
are low setting and bolt load loss (also
in case of wide bolt spacing), low clamping force requirements for high sealing
potential, plus high elasticity and durability.
Application areas
ACM 50 and ACM 60 provide a high
sealing potential at low clamping forces.
Similarly, setting tendency and bolt
load loss are low, even with wide bolt
spacing. As a result, this gasket material is preferred for flexurally weak components with low surface pressures,
e.g. for oil pans and valve cover modules.
Application example
The metal/rubber material ACM 50 is
used for backbone-molded gaskets on
valve covers. Ensuring top quality: To
position the core sheet precisely during
the production process, it is held by
means of special locating pins. Apart
from perfect sealing, the subject of NVH
(noise, vibration, harshness) also plays
a decisive role.
ACM 50 – a solution that's not only tight,
but also quiet.
Trend
ACM 50 and ACM 60 provide cost-effective standard solutions not only for
all classical applications, but also customized solutions for modern engine
design. In short – an excellent tip.
Moreover, ACM 50 and ACM 60 are
finding increasing use in applications
with very high demands on durability,
and for components with distortion problems.

HTV 50 – THE SIMPLE SOLUTION FOR SPECIAL PURPOSES
Material
HTV 50 consists of a metal core with
molded-on silicone elastomer profiles.
The core is made of stainless steel
(e.g. type 1.4303) or galvanized carbon
steel. Silicone rubber with a hardness
of 50 Shore A is used as elastomer.
HTV stands for High Temperature Vulcanization.
The silicone rubber is edge-molded to
the metal core. Hereby, the moldings
are always used as force shunts, whereby travel limiting is ensured e.g. by
means of a groove in the component.
Properties
Due to its outstanding flow properties,
HTV 50 is very simple to apply and
process, so that retro-vulcanization is
not necessary. Its temperature resistance lies in the range between -40 °C
and +200 °C. Other positive features
are low setting and bolt load loss (also
in case of wide bolt spacing), low clamping force requirements for high sealing
potential, plus high elasticity and durability. The material is conditionally oilresistant.
Application areas
HTV 50 is the ideal solution for all standard applications. In particular for sealing tasks involving covers and electrical
connectors.

XTREME ® PLUS – WHEN EXTREME TEMPERATURES REPRESENT AN ABSOLUTE CHALLENGE
Material
Xtreme® plus consists of a tanged steel
core, onto which a fiber-reinforced mica
layer is rolled from both sides. The core
material is a 0.20 mm thick stainless
steel (type 1.4828) sheet that has been
tanged. Apart from expanded mica,
the coating material contains temperature resistant fibers as well as a small
amount of high-grade elastomers as
binder. Due to the special properties of
the mica material, which prevents the
gasket from burning-in or baking to
the sealing surface, a non-stick coating is not necessary.
The material is available in overall thicknesses of 1.2 mm and 1.6 mm.
Properties
Xtreme® plus withstands high temperatures up to 950 °C, and provides a
high sealing potential over the entire
temperature range. Due to its high compressibility and elasticity, this gasket
material is extremely conformable,
compensates component deformations
in an optimal manner, and exhibits constant material properties also under
changing operating conditions.
Further advantages are high creep resistance, i.e. a low setting tendency,
good media resistance, high gas tightness, and good thermal insulation with
a low coefficient of thermal conductance.
Under extreme mechanical loads, the
optional internal bead permits higher
internal pressures and provides better
cross-sectional sealing.
Wider beads reduce the gasket's setting
behaviour. If required, a one-sided bead
up to the gasket's outer contour increases mechanical strength and improves the gliding properties through
special measures.
Application areas
Xtreme® plus was developed especially
for high-temperature applications, and
therefore provides optimum solutions
for all tasks in the exhaust area. It is
particularly suitable for turbocharger
gaskets, but also for installation between
cylinder head and exhaust manifold, in
the downstream flanges of exhaust
trains, and for components in EGR systems.
Application example
The preferred use of Xtreme® plus is
for turbocharger gaskets. Here, Xtreme®
plus compensates component movements caused by large temperature
variations very well. For special solutions, the gaskets usually have metal
beaded edges.
Trend
Tighter emission regulations have a
decisive influence of engine development, whilst engines are becoming
more compact and have higher outputs.
This leads to higher exhaust gas temperatures and simultaneously higher
combustion pressures. In summary,
the engine has fewer opportunities for
cooling down. The high-temperature
gasket material Xtreme® plus is ideally
suited to meet these demands.

SCREEN-PRINTED GASKETS SH, QE, AND SF – INDIVIDUAL TUNING FOR FLAT GASKETS
Material
Screen-printed gaskets are manufactured by applying polymer compound
beads onto a substrate material, and
subsequent vulcanization of the compact or foamed elastic sealing beads.
Depending on the application and the
substrate material, special bonding
lacquers are used, which also act as
corrosion inhibitors with carbon steel
substrates.
The substrate material can be metal or
composite, i.e. carbon steel, stainless
steel, or aluminium, as well as AFM® –
our asbestos-free composite material
based on synthetic fibers.
Also depending on the application, the
beads have different specifications.
Properties
Screen-printed gaskets achieve significantly better micro and macro-adaptation, and therefore improve the sealing
effect and internal pressure resistance
of flat gaskets. The printed beads can
be applied on one or both sides of the
gasket.
SH-type material exhibits good resistance to mineral oils and greases, has
high mechanical strength, and therefore
permits high line pressures.
QE is resistant to a wide range of media,
is temperature resistant and non-aging.
Moreover, the sealing bead is highly conformable and only requires low clamping pressure to obtain good sealing
results.
Due to the foaming process, SF-type
material is extremely conformable, and
has a medium temperature resistance.
Application areas
Screen-printed gaskets are always used
when conventional gaskets are unable
to provide adequate sealing results.
Even the standard design with constant

sealing/supporting bead heights and
widths ensures good sealing integrity,
especially with flexurally weak components and/or low clamping pressures.
By varying the bead geometry, it is possible to control the surface pressure
precisely, e.g. for joints between different pressures or media.
For timing covers, oil pans, or hydraulic
pumps, screen-printed gaskets enable
practically every bead shape to be implemented without complex tooling.
Application example
Due to uneven pressure distribution as
well as the partially low clamping pressure, flexurally weak components place
high demands on flat gaskets. Elastic
polymer sealing beads can solve these
tasks optimally, for example on timing
covers.
Trend
Innovative engine concepts depend on
gaskets that are matched to the specific
application. Screen-printed gaskets
permit special solutions to be realized
quickly and unconventionally. Due to
the line pressure effect, high-integrity
surface and cross-sectional sealing is
achieved. Consequently, the component
stiffness or clamping pressure required
for a good seal can be lower than with
simple flat gaskets.

Molded rubber gaskets
ACM 50 AND ACM 60 – MAXIMUM SEALING POTENTIAL WITH MINIMUM CLAMPING FORCE
Material
ACM 50 and ACM 60 are molded rubber
gaskets using acrylic rubber. The elastomer elements are always used as force
shunts, whereby travel limiting is ensured e.g. by means of a groove in the
component or with threaded buffers.
Profile geometries matched precisely
to the application are the guarantee for
optimum functionality. ACM 50 and
ACM 60 have different hardness grades.
The hardness of ACM 50 is 50 Shore A,
whilst that of ACM 60 is 60 Shore A.
Properties
ACM 50 and ACM 60 provide a high
sealing potential at low clamping forces.
Similarly, setting tendency and bolt load
loss are low, even with wide bolt spacing. The cost-effective standard solution
is suitable for a wide temperature range
between -30 °C and +150 °C, and has
very good resistance against oil.
Equally convincing are the elasticity and
durability of ACM 50 and ACM 60.
Application areas
The properties of ACM 50 and ACM 60
are perfect for reliable sealing of flexurally weak components, as these
cases only permit limited clamping
forces.
ACM 50 and ACM 60 are used mainly
for valve cover gaskets, but also for oil
pans and timing covers.

Application example
Especially with valve cover gaskets, reliable sealing must be ensured in spite
of wide bolt spacing or unfavorable
creep behavior in the case of plastic
valve covers. In combination with the
special 'H' profile, ACM 50 and ACM 60
achieve an optimum overall performance. Due to its high recovery rate,
a wide working range, and a defined
buckling characteristic, the profile is
pushed up automatically to ensure a
tight seal.
Trend
Also in future, flexurally weak plastic
components will play an important role
in modern lightweight engines. ACM
50 and ACM 60 provide good standard
solutions that can also be used for plastic components with a tendency to
creep. Similarly, this gasket material is
finding increasing use for housing covers made of aluminium or magnesium.

FIRMLY BONDED SEALING COMPOUNDS DX AND F52 – RELIABLE SEALING IN CRITICAL SITUATIONS
Application areas
When applied in the form of a bead, DX
is used to seal highly uneven and rough
surfaces. F52 is used in situations involving high component dynamics and/or
elevated temperatures, and requiring
chemical resistance.
Material
Critical sealing conditions arise in cases
of component deformation, high surface
roughness, and in separation areas.
These difficulties can be solved by applying highly plastic sealing compounds
to the gaskets. During installation, the
compound is compressed, thus ensuring a reliable seal also in critical situations.
For this purpose, either the firmly bonded and cured DX compound based on
polyurethane (PU) or the foamed fluorine
rubber (FPM) F52 compound are used.
Properties
The sealing compounds DX and F52
are temperature resistant up to 120 °C
and 240 °C respectively, and resistant
to various media such as engine oil
and coolants. Both compounds have
good bonding properties.
Due to their outstanding flow characteristics, the compounds extrude into
the smallest cavities, surface roughnesses, and gaps without causing a
partial reduction of the gasket's
mounting surface pressure.

F52
Design versions of firmly bonded sealing compounds DX and F52.
¬ 48
Application example
The firmly bonded sealing compound DX
is used typically for the joints of vacuum pumps, whilst F52 is used e.g. in
critical sealing conditions with oil pans.
Trend
Complex engine designs increasingly
require gaskets with additional seals.
The aim is to eliminate the need to
apply the additional seal during installation, and to deliver the gasket complete with compound as a »modular
solution« instead.

WAVE-STOPPER ® – PUTTING PRESSURE ON THE LINE
pressure image can be created in the
critical areas. Due to the great degree
of design freedom, the Wave-Stopper®
is able to adapt perfectly to changing
component stiffness. This permits pressure peaks to be equalized, and the
pressures on adjacent components are
distributed evenly. Typical application
areas are exhaust manifold, exhaust
pipe, and turbocharger.
Material
Normally, the Waver-Stopper® consists
of several concentric individual waves.
The wave characteristics are influenced
by various design criteria, and the core
sheet thickness. By means of partially
terminated waves, the gasket can be
individually adapted to the component
stiffness and contour.
Properties
The Wave-Stopper® exhibits pronounced
plastic/elastic behavior, which can be
matched precisely to the gasket's working environment. Moreover, the wave
height profiles can be varied, thus permitting a topographic adaptation.
Consequently, the available bolt clamping forces are utilized to better effect,
and component distortions are reduced.
Application example
Wave-Stopper® achieves excellent results in turbochargers with thermal distortion of the sealed joints. Together
with additional beads, the plastic/elastic behaviour ensures adequate sealing
pressure levels under all operating conditions, and thus provides optimum
sealing.
Application areas
The Wave-Stopper® is used primarily
in combination with gaskets that must
achieve high line pressures due to yielding components or because of high temperature stresses. Thanks to the individual adaptability, a highly uniform

CLIPS, CLAWS, AND FASTENERS – FAST, SIMPLE, AND SECURE
Material
Various types are available, such as the
REINZ fixing claw, the REINZ dome, or
other special versions of clips and fasteners.
Basically, all the different types and versions can be used with all beaded metal
gaskets – with and without elastomer
coating.
Properties
Clips and fasteners serve to hold flat
gaskets securely in place. This is always
necessary if the gasket is preassembled
by a systems supplier, or if it must be
prevented from falling during installation
on the assembly line.
Application areas
Clips, claws, and fasteners are used in
countless applications – from A for airbag housing to W for water pump. In
short: Whenever the loss of gaskets from
preassembled engine components must
be prevented, or their installation on the
assembly line is to be simplified.
Application example
Positioning and securing. Occasionally,
combinations of different types of clips,
claws, and fasteners are used, for example in complex oil filter cooler modules. During installation, the gasket must
be positioned precisely (dome), before
it can be secured overhead (clip or claw)
to prevent it falling.
Trend
Faster, simpler, and safer are today's
key words. Detailed solutions using innovative fasteners are extremely useful
during efforts to simplify installation or
assembly, thereby reducing overall costs.

Integral clips ensure simple (overhead) installation.

A vision for the future
HELPING CREATE FUTURE
ENGINE CONCEPTS
TWO EXAMPLES OF THE
AUTOMOTIVE FUTURE
By constantly evaluating market and
technology trends, VICTOR REINZ is
helping make visions become reality.
In fact, many of today’s engine standards are based on innovative solutions from VICTOR REINZ. So it's no
wonder that VICTOR REINZ has developed a strong reputation for ongoing,
outstanding product innovations in the
automotive industry.
SENSORICS ®
The amount of vehicle electronics continues to increase. Measurement and
control will play an essential role in
modern engines. For example, integrated sensors enable fuel consumption
and emissions to be reduced significantly. However, this also involves new demands on sealing technology for modern
engine designs. In future, sensors in
the head gasket will measure temperature and pressure directly in the combustion chamber, to supply data about
the combustion process to the engine
management system. Electronic components inside the engine control fuel
injection, the ignition, and/or the valves,
which means that the electric signals
must be fed to the outside via the gasket.
Solutions for the automotive future come
from VICTOR REINZ. The active cylinder
head gasket SensoriCS® for pressure
and temperature measurement, and the
Window Gasket for the feedthrough of
electronic signals are just two outstanding examples of VICTOR REINZ innovation.
With VICTOR REINZ, automotive visions come true.
In the future, a cylinder head gasket
will no longer be simply a sealing element – it will be an intelligent component in the overall engine system. In
fact, at VICTOR REINZ the future is
now: SensoriCS® – the intelligent MLS
head gasket with integrated pressure
and temperature sensors – helps provide an intelligent engine management
and cooling system.
Pressure measurement Δp
To further reduce emissions and improve
fuel consumption in future IC engines,
measuring the combustion pressures is
a must. This measurement will permit
the engine management system to influence the combustion process far more
precisely. Through active control factors
including injection time and quantity, as
well as EGR ratio, the engine operates
only in the optimum map area, so that
emissions and fuel consumption are reduced. What's more, this system enables
the engine's combustion parameters to
be adapted effectively and flexibly to
different fuel qualities.

Also here, temperature sensors supply
data to the engine management system,
directly from inside the engine – permit-
ting the coolant flow to be controlled
for optimum exploitation of the generated heat. Exact, requirement-dependent
heat management of the coolant circuit
enable the engine and catalytic converter to reach their ideal operating temperatures much faster. Similar application possibilities are also possible in the
areas of optimized combustion and onboard diagnostics. These technological
advances will provide higher engine
efficiency while simultaneously reducing
harmful emissions, lowering fuel consumption, and lengthening the service
life of critical components.
WINDOW GASKET
The VICTOR REINZ Window Gasket allows the simple feedthrough of electronic signals without additional holes, e.g.
in the engine block, and the risk of leakage channels. This unique concept
permits the installation of one or more
cable harnesses as well as the use of
variable plug-in connections, such as
power leads for solenoids, switches,
fuel injection, or sensors. Moreover,
through the use of thermoplastics for
the substrate in combination with hightemperature resistant elastomers for
the sealing elements, the design exhibits excellent performance. Typical
application areas for this new technology are valve cover seals, oil pan gas-
kets, gearbox gaskets, and similar sealing functions. The Window Gasket avoids
potential leakage paths due to conventional installation methods, reduces
component complexity, is easy to install,
and ensures simple disassembly and
reassembly, for example during repair
operations.
