Swagelok SS-8-VCR-CP VCR Face Seal Fitting Cap

Swagelok SS-8-VCR-CP is a 316 stainless steel VCR face-seal cap designed for 1/2 in. VCR fittings, sold as a two-pack. This cap protects the face-seal area of a VCR connection when the fitting is not in use, helping maintain cleanliness and preventing contamination in high-purity vacuum and process systems. Constructed from 316 stainless steel, the cap is compatible with Swagelok’s VCR metal gasket face-seal fittings, providing a leak-tight closure that preserves system integrity across a range of temperatures and pressures. As part of Swagelok’s family of VCR caps and plugs, it complements other sizes such as 1/4 in. and 3/4 in. caps (for example SS-4-VCR-CP and SS-12-VCR-CP), enabling consistent end-capping across different VCR connection sizes. The SS-8-VCR-CP specifically applies to half-inch VCR fittings, delivering a durable, corrosion-resistant cap that protects the gasket face during storage, handling, or downtime and helps maintain the purity and performance of vacuum systems and process lines.
