Swagelok D-316-QC6 Quick Connect Coupler QC6

The Swagelok D-316-QC6 Quick Connect Coupler is a 316 stainless steel instrumentation quick-connect designed for fast, leak-resistant connections in process and laboratory lines. As part of the QC6 family, it features a valve-enabled stem and a 3/8 in. Swagelok tube-fitting interface, delivering a typical 0.5 Cv flow coefficient that supports predictable gas or liquid transfer during make-and-break operations. The body and stem are constructed from 316 stainless steel, and fluorocarbon O-rings (FKM) are standard for this material set, providing broad chemical compatibility and robust sealing across common instrumentation fluids. This assembly is intended for frequent connections with minimal air inclusion and spillage, making it well suited for instrumentation loops, sampling lines, calibration setups, and test rigs in both laboratory and production environments where reliable, repeatable connections are essential.
