Swagelok S-1610-3 Tube Union Tee 1 Inch Fitting

The Swagelok S-1610-3 is a carbon steel three-port tube fitting (a union tee) sized for 1 in. tube OD, designed to connect three 1 in. runs in a single assembly. The basic ordering number is S-1610-3, and the body is carbon steel for robust, general‑purpose service in tubing systems that use Swagelok tube fittings. This model provides three 1 in. tube OD ports and is part of Swagelok’s family of tube fittings, with stainless steel (SS-1610-3) and brass (B-1610-3) variants available for different service requirements. The 1 in. tube OD sizing ensures compatibility with standard 1 in. tubing across Swagelok’s catalog, and the union tee configuration supports a three-way junction in tubing networks where three runs intersect.
