Swagelok SS-16-TSW-9 Socket Weld Union Fitting

SS-16-TSW-9 is a 316 stainless steel tube socket weld union elbow for 1 in. OD tubing. It features Swagelok’s tube socket weld (TSW) ends that form a permanent, leak-tight 90-degree connection when welded to tubing, making it suitable for compact high-purity piping systems. Constructed from 316 stainless steel, the fitting provides corrosion resistance in demanding chemical, pharmaceutical, and semiconductor environments. The 90° elbow configuration allows routing around obstacles while preserving flow characteristics, and the socket weld interface supports cleanability and strong mechanical integrity in tight spaces. Common applications include process lines in chemical processing, semiconductor fabrication, and pharmaceutical manufacturing where a reliable 1 in. socket-weld elbow is required. As part of Swagelok’s weld-fittings family, SS-16-TSW-9 delivers a robust solution for high-purity, industrial piping with a compact footprint.
