Swagelok VCR 4 Face Seal Fitting, 1/4 in. Gasket, PTFE Plastic, Non-Retained Style Gasket. PN: T-4-VCR-2

This Swagelok® VCR® Non-retained gasket is made of PTFE plastic which maintains a greater flex-life. PTFE are among the most chemically inert materials available. Standard cleaning and packaging (SC-10).

These VCR (Vacuum Coupling Radiation) fittings and components are precision manufactured and offer a leak-tight, metal on metal seal. They can be used for any fluid flow application and provide leak-tight service from vacuum to positive pressure.

Polished surface finish and high purity materials virtually eliminate these fittings as a source of system contamination. The VCR fitting design has been tested to maximum leak rate of 4x10^-9 std cm3/s with silver-plated-copper gaskets, and to a maximum leak rate of 4x10^-11 std cm³/s with unplated (Ni, Cu or 316L SS) gaskets.
