Stainless Steel 3/8 Union Tee – 316 Stainless Steel Tube Fitting (SUT-6)
The SUT-6 is a 3/8" stainless steel union tee built for instrumentation, fluid transfer, and high-pressure setups. It offers a precise, leak-tight connection for three tube runs in a compact T-shaped layout — ideal for applications where clean design and directional flow are critical.
Made from 316 stainless steel, the SUT-6 resists corrosion in harsh and hygienic environments. It’s built to handle frequent clean-in-place (CIP) cycles and supports process reliability in industries like biotech, food-grade systems, and pharmaceutical production.
With easy installation, repeatable performance, and compatibility with standard fittings, the SUT-6 gives engineers a trusted solution for building or maintaining critical systems that demand sanitary performance and precise fluid control.
Key Benefits
- Seal: Metal-to-metal union design, no sealants needed
 - Durability: Handles vibration, pressure cycling, and frequent cleaning
 - Maintenance: Reusable and simple to disassemble
 - Compatibility: Connects seamlessly with stainless or polymer tubing
 - Material: 316 stainless steel ensures long service life in corrosive environments
