VCO O-Ring Face Seal Fittings
Features
Swagelok VCO O-ring face seal fittings
are designed for rapid assembly in
pipe, tube, and welded systems.
O-ring
contained
completely
for maximum
efficiency
■ Unique design allows easy
Female nut threads
silver plated for
easy assembly
VCO Body
■ No axial clearance is required.
■ Sealing is accomplished with
a captive O-ring in the body
component.
■ Assemblies can be used from high
pressure to critical vacuum, within a
wide range of temperatures.
VCO Gland
VCO Nut
Smooth finish on
gland face ensures
positive seal
Testing
The VCO face seal fitting design has been helium leak tested
to a m
­ aximum leak rate of 4  10­–9 std cm3/s.
Ordering Information and Dimensions
■ Dimensions are for reference only and are subject to change.
■ The E dimension refers to the smallest nominal inside diameter of the part.
