O-ring face seal fitting
1/8 - 1" | VCO® SWAGELOK

Swagelok® VCO O-ring face seal fittings are designed for rapid assembly in pipe, tube, and welded systems. The "B" Type VCO fitting, for applications in biotechnology and pharmaceutics, uses an L-ring seal that eliminates concavity at the bore.

Unique design allows easy installation where space is limited.
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.
O-ring contained completely for maximum efficiency.
Test ports at two locations for easy leak testing.
Female nut threads silver plated for easy assembly.
Smooth finish on gland face ensures positive seal.

Testing
The VCO face seal fitting design has been helium leak tested to a maximum leak rate of 4 × 10-9 std cm3/s.

Options
Fluorocarbon FKM O-rings are standard. Perfluoroelastomer, Buna N, PTFE, and ethylene propylene O-rings are available.
