Plating
VCR female nuts are silver plated. Avoid chemical processes
used for cleaning, electropolishing, and passivation that will
remove plating. If the plating is damaged or removed, thread
galling may occur, damaging fitting components and preventing
a proper seal.

■ Dimensions, in inches (millimeters), are for reference only
and are subject to change.
■ The E dimension refers to the smallest nominal inside
diameter of the part (see ordering tables).
Testing
The VCR fitting design has been helium leak tested to a
maximum leak rate of 4 10–9 std cm3/s with silver-plated
and copper gaskets and to a maximum leak rate of 4 10–11
std cm3/s with unplated gaskets.
VCR Metal Gasket Face Seal Fittings
Ultrahigh-Purity
Ordering Information
A variety of VCR face seal glands and bodies is available
with controlled surface finishes, electopolished, and specially
cleaned to meet ultrahigh-purity system requirements. For
more information, see Swagelok ® Ultrahigh-Purity Process
Specification (SC-01).
To order fittings manufactured according to Swagelok
Ultrahigh-Purity Process Specification (SC-01), add P to the
ordering number.
Example: 6LV-4-VCR-3-4TB7P
Side-load retainer gasket for easy installation
and minimal clearance for removal
Designator
Roughness
Average, Ra
P
5 µin. (0.13 µm)
Test port at two locations
for easy leak testing
Standard surface finish on glands
and bodies is a roughness average
of 10 µin. (0.25 µm) Ra
Markings identify manufacturer, material, and
when applicable, the appropriate process
designator according to Swagelok UltrahighPurity Process Specification (SC-01)
No “virtual leak” zones
Precision manufactured gasket
for maximum performance
Female threads are silver-plated to
prevent galling, ensure easy assembly
and consistent make-up
Material heat code is
stamped on glands and
all shapes to ensure raw
material traceability
VCR components offer the high purity of a metal-to-metal seal,
providing leak-tight service from vacuum to positive pressure.
The seal on a VCR assembly is made when the gasket is
compressed by two beads during the engagement of a male
nut or body hex and a female nut.
