Swagelok 316L-16TB7-3 Stainless Steel Tube Butt Weld Union Tee

Swagelok 316L-16TB7-3 is a 316L stainless steel tube butt weld union tee sized for a 1-inch run, part of Swagelok’s family of union tees. The fitting features two butt-weld ends and a third branch connection, enabling a secure branch off a running line in process piping. Constructed from 316L stainless steel, it offers excellent corrosion resistance and is suited for high-purity and chemical-service applications, including environments common in chemical processing, semiconductor fabrication, and pharmaceutical settings. The 316L-16TB7-3 family includes reducing configurations such as 316L-16TB7-3-16-8, which provides a 1-inch run with a smaller 1/2-inch branch, allowing taps off the main line without additional adapters. When paired with Swagelok-compatible tubing, these fittings are designed to maintain system integrity in cleanroom and other demanding industrial environments where cleanliness and corrosion resistance are critical. This part is intended for permanent, leak-tight connections in stainless steel piping systems and integrates with Swagelok’s range of 316L fittings, tubes, and tooling to support high-purity fluid handling.
