Swagelok 316L-16TB7-6-8 Tube Butt Weld Reducing Union

Swagelok 316L-16TB7-6-8 is a stainless steel tube butt weld reducing union that accepts 1 in. and 1/2 in. outer-diameter tubing. Manufactured from 316L stainless steel, this reducing union provides a permanent, leak-tight weld joint by joining tube ends to the fitting without compression fittings. The part number identifies the 1 in. x 1/2 in. OD configuration, enabling a single fitting to transition between two tube sizes. Designed for process piping where corrosion resistance and structural integrity are important, it accommodates welded connections in systems that route stainless tubing. As a reducing union, it consolidates a size change within one component, reducing the number of joints and potential leak points in tight or high-pressure runs. The butt weld ends are intended for fusion welding to matching tube ends and are compatible with Swagelok’s 316L stainless steel tubing and weld fittings family.
