Stainless Steel Union – 5/8" Tube OD Compression Fitting (SU-10)
The SU-10 is a 5/8" stainless steel compression union designed for high-integrity tube-to-tube connections in sanitary and industrial systems. Machined from 316 stainless steel, it delivers exceptional corrosion resistance and mechanical reliability in Clean-in-Place (CIP) instrumentation and hygienic process lines.
This fitting provides consistent, leak-tight sealing and is built to withstand vibration, pressure cycling, and aggressive cleaning agents. It’s commonly used in food-grade, biotech, and pharmaceutical environments where system cleanliness and performance are critical.
As a direct Swagelok® SS-1010-6 equivalent, the SU-10 integrates seamlessly into high-purity assemblies, offering engineers a reliable solution for use with 5/8" stainless tubing in OEM skids, gas sampling setups, and sanitary piping layouts.
Key Benefits
- Seal: Compression union design ensures leak-tight metal-to-metal sealing
 - Durability: Performs under pressure, vibration, and CIP cleaning cycles
 - Maintenance: Reusable and easy to reinstall without seal degradation
 - Compatibility: Fits standard 5/8" stainless steel tubing
 - Material: 316 stainless steel supports sanitary, industrial, and high-purity systems
 
Typical Applications
- Sanitary processing lines
 - Clean-in-Place (CIP) instrumentation systems
 - Gas sampling and monitoring panels
 - Original Equipment Manufacturer (OEM) skids
 - Biotech and food-grade fluid setups
