Swagelok SS-QC8-B-8PMK2 Quick Connect Fitting

SS-QC8-B-8PMK2 is a stainless steel instrumentation quick-connect body from Swagelok’s QC8 family, designed for fast, leak-tight connections in instrumentation lines. It features a 1/2 in. male NPT thread for mating with standard 1/2 in. NPT components and a flow coefficient (Cv) of 1.3, enabling predictable flow in test, sampling, and analytical setups. As a member of the QC8 quick-connect family, this body is compatible with Swagelok stems and sleeves, and any QC8 stem will fit any QC8 body for interchangeability. The -K2 suffix identifies this item as a Plumbing Service Kit variant, which includes kit components to support field maintenance of the quick-connect assembly. Typical applications include instrumentation loops, where rapid connect/disconnect capability and robust stainless-steel construction are advantageous for calibration, sampling, testing, and analytical work. Verify mating compatibility with your existing stems and sleeves to ensure proper fit and performance.
