Cylinder-head gaskets.
Highly effective, reliable, customized.
As key components of modern combustion engines, cylinderhead gaskets help to ensure that engines run efficiently, safely
and economically. They provide a reliable seal for fuel gas, coolants and engine oil. As a load transmission element between
crankcase and cylinder head, they also have a considerable
influence on the distribution of forces within the entire enclosed
system and on the resulting elastic component deformations.
Cylinder-head gaskets from ElringKlinger are a leading brand
worldwide. Whether for cars or commercial vehicles, our
Metaloflex™ and metal-elastomer cylinder-head gaskets offer
the right sealing system for any engine design.

The serpentine stopper makes ideal use of the area for the stopper dictated by engine geometry. A wave-shaped “microbead”
creates a thickening that can replace the previously used laserwelded stoppers while offering almost identical rigidity. The
reason for this is that the numerous windings resulting from
the wave geometry increase stopper rigidity, preventing it from
settling during engine operation and becoming overly elastic. If
the stopper were to become too elastic, it would increase sealing gap oscillations in the engine under ignition pressure and
therefore adversely affect the durability of the system.

Specialty gaskets.
Extremely versatile. Extremely tough.
For the various sealing jobs in engine, transmission, exhaust gas system and auxiliaries (e.g. compressors or pumps), ElringKlinger offers efficient, customized product solutions: Metaloseal™,
Volumesoftseal™, Metaloprint™, soft material, metal-elastomer and elastomer sealing systems. Materials and design are optimally matched to the specific requirements. The integration of additional
functions like heat shields, strainers, sensors and pre-assembly elements complete the ElringKlinger
sealing system range. More than 135 years of experience in sealing technology are the basis for our
extensive development and manufacturing expertise.

Metaloseal™ is a highly effective sealing system based on coated
and uncoated metal carrier materials. In “L” type gaskets (line
sealing), metal beads or elastomer lips reduce the sealing pressure to a line compression. As a result, higher sealing pressures
can be achieved at constant bolt force, or constant sealing pressures at lower bolt forces. Thanks to the wide range of combination options between elastomer and metal carrier material and
the single- or multi-layer structure, this sealing system can be
used for virtually all applications.

This system for sealing highly stressed components consists of a
metal carrier with integrated elastomer profiles. It is particularly
suitable for load-carrying joints. The elastomer materials used
are developed and produced in-house by ElringKlinger. Thanks
to modern injection molding technologies, various materials can
be bonded to a carrier in metal or plastic. As a result, it is possible

Elastomer specialty gaskets can be used on nearly all sealing
joints within the engine. A pressure-boundary flanged connection has to be created for elastomer sealing systems in the case
of load-carrying joints, e.g. by means of a groove in the component. Specifically matched profile geometries ensure maximum
functionality at very low sealing pressures.

The control plates used to seal off the control unit of automatic and
dual-clutch transmissions have to withstand high hydraulic pressures and often highly fluctuating thermal loads. ElringKlinger
offers four different systems, depending on component features
and operating parameters: Metaloseal™, Metaloprint™, metal/
soft material and plastic transmission control plates. Not only is
an excellent seal achieved at all operating points, but drive train
efficiency can also be further enhanced as a result.
