Stainless Steel Union Tee – 3/4" Tube OD Instrumentation Fitting (SUT-12)
The SUT-12 is a 3/4" stainless steel union tee built for precision tube-to-tube connections in sanitary and industrial fluid systems. Manufactured from 316 stainless steel, it offers corrosion resistance and structural integrity in Clean-in-Place (CIP) instrumentation environments and other demanding conditions.
This compression-style fitting is a dependable solution for maintaining flow control in hygienic fluid processors, process skids, and food-grade or pharmaceutical piping layouts. Its union tee design allows clean directional flow and layout flexibility without compromising sealing integrity.
Engineers choose the SUT-12 for its reusability, ease of installation, and compatibility with standard instrumentation fittings. Whether you’re constructing an Original Equipment Manufacturer (OEM) build or upgrading an existing sanitary system, it delivers high-performance fluid control in tight configurations.
Key Benefits
- Seal: Compression union provides a tight, leak-free seal with no sealants.
 - Durability: Built to handle high pressure, vibration, and frequent CIP. cycles.
 - Maintenance: Fully reusable and easy to reposition.
 - Compatibility: Works with 3/4" stainless tubing an sanitary valve systems.
 - Material: 316 stainless steel supports cleanroom and hygienic fluid processing.
 
Typical Applications
- Sanitary tubing systems
 - Clean-in-Place (CIP) instrumentation
 - Original Equipment Manufacturer (OEM) builds
 - Process skids and modular fluid systems
 - Hygienic valves and lab instrumentation setups
