This Swagelok® VCR® Plug fitting is made of 316 Stainless Steel. Swagelok Part Number: SS-2-VCR-P.

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 SS) gaskets.
