Swagelok 316QC42 Stainless Steel Quick Connect Fitting is a 316 stainless‑steel quick‑connect in Swagelok’s QC family, engineered for fast, tool‑free connections in instrumentation and process lines. Built for frequent connect/disconnect cycles, it minimizes air inclusion and spillage while delivering a dependable seal when mated with Swagelok tube fittings in demanding environments. In common QC configurations, Swagelok uses fluorocarbon FKM O‑rings on a stainless body to resist chemical attack, and the stainless construction provides robust corrosion resistance in high‑purity gas and liquid services, making it suitable for analytical systems, sample lines, and laboratory instrumentation installations.
