Stainless Steel Union Tee – 1/2" Tube x Tube x Tube (SUT-8)
The SUT-8 is a stainless steel union tee designed to form a clean, leak-tight junction between three 1/2" tubing lines. All three ports feature compression ends, making it easy to assemble or service without requiring sealants or threaded adapters.
This precision-machined union tee is made from 316 stainless steel for long-term durability, corrosion resistance, and compatibility with Clean-in-Place (CIP) systems. It’s ideal for branching off instrumentation lines, panel tubing, or Original Equipment Manufacturer (OEM) fluid skids where modular assembly and high-integrity connections are essential.
Its dual-ferrule compression design ensures a vibration-resistant, reusable seal with minimal maintenance—even under pressure cycling or temperature fluctuations.
