Swagelok QC4316 Stainless Steel Quick Connector

Swagelok QC4316 Stainless Steel Quick Connector is a member of the QC4 instrumentation quick-connect family, delivering fast, repeatable connections in process, analytical, and laboratory instrumentation lines. Constructed from stainless steel (316-grade variants are standard in QC4 components), it offers robust corrosion resistance for demanding environments. The QC4 series is built for frequent, tool-free connections with minimal air inclusion and spillage, a key advantage for sampling lines, gas and liquid instrumentation, and test rigs. Configurations in the QC4 line commonly feature a 0.2 Cv flow coefficient and support end connections such as 1/4 in. and 6 mm Swagelok tube fittings, enabling quick mating with compatible bodies and stems for inline or panel-mounted installations. This combination enables rapid connect/disconnect with reliable sealing, helping to minimize downtime during setup, maintenance, and experiments in lab or plant environments.
