Features
Swagelok® VCR fittings offer the high purity of a metalto-metal seal, providing leak-tight service from vacuum to
positive pressure.
Minimal clearance
required for removal
Side-load retainer gasket for
easy installation and minimal
clearance for removal
VCR
FITTINGS
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.
Test port at two locations for
easy leak testing
Markings identify manufacturer,
material, and when applicable,
the appropriate process
designator, in accordance
with Swagelok Ultrahigh-Purity
Process Specification (SC‑01),
(MS-06-61), page 1180.
Standard surface finish on
glands and bodies is a roughness
average of 10 µin. (0.25 µm) Ra
No “virtual leak” zones
Precision manufactured gasket
for maximum performance
Female threads are silver plated
to prevent galling, ensure easy,
consistent assembly

➀ 20 % minimum elongation allowed.
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.
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.

Ultrahigh-Purity Processing
Components are cleaned to remove oil, grease, and loose
particles. For more information, see Swagelok Standard
Cleaning and Packaging (SC-10) (MS-06-62), page 1174.
A variety of VCR face seal glands and bodies is available
with controlled surface finishes, electropolished, and
specially cleaned to meet ultrahigh-purity system
requirements. For more information, see Swagelok UltrahighPurity Process Specification (SC-01) (MS-06-61), page 1180.
