Stainless Steel Union Tee – 3/4" Tube OD Instrumentation Fitting

The SUT-12 is a 3/4" stainless steel union tee designed for secure, high-integrity tube-to-tube connections in pressure systems, hygienic fluid processors, and industrial applications. Constructed from 316 stainless steel, this corrosion-resistant alloy fitting supports clean in place instrumentation and precise fluid control in demanding environments.

● Material: 316 Stainless Steel (Corrosion-Resistant Alloy)
● Connection Type: 3/4" Tube OD – Union Tee
● Applications: Sanitary tubing systems, CIP loops, process skids, OEM builds, hygienic valves, lab instrumentation

This 3/4" tube tee—also referred to as a compression tee, 3/4" union tee, or instrumentation fitting—is an ideal alternative to Swagelok (equivalent: SS-1210-3). It’s built to perform under pressure while maintaining tight sealing in sanitary stainless steel piping systems.

Engineers and technicians rely on the SUT-12 for hygienic-grade installations where flow direction control and layout flexibility are essential. Whether you’re designing a cleanroom setup or scaling a food and beverage process line, this union tee delivers lasting performance, easy installation, and full compatibility with standard instrumentation fittings.
