Swagelok 316QC42 Stainless Steel Quick Connect Fitting

Swagelok 316QC42 Stainless Steel Quick Connect Fitting is a QC4-series instrumentation quick connect from Swagelok, manufactured in 316 stainless steel for corrosion resistance in demanding environments. Designed to enable rapid, repeatable connections in instrumentation lines, sampling loops, and test manifolds, it preserves cleanability and chemical compatibility critical in lab and process settings. The QC4 family includes both valved stems and stem-only configurations, with representative part numbers such as SS-QC4-D-6M0 (316 SS, with valve) and SS-QC4-S-6M0 (316 SS, stem without valve), illustrating typical 6 mm sizing options used in many installations. O-rings are fluorocarbon (FKM) and standard for 316 SS variants in this family, contributing to reliable sealing across gas and liquid services. As with all Swagelok quick connects, these fittings are designed for fast, tool-free connections and straightforward disconnection, enabling efficient maintenance and reconfiguration of instrumentation loops in chemical processing, pharmaceutical, and research environments.
