Description

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
