Stainless Steel Tube Union – 3/4" Tube OD | Compression Fitting

The SU-12 is a 3/4" tube OD compression union built for secure, straight-line connections in high-pressure and sanitary systems. Machined from 316 stainless steel, it offers strong corrosion resistance and dimensional precision, making it a solid choice for clean piping assemblies and process-critical instrumentation builds.

Designed for Clean-in-Place (CIP) instrumentation, OEM skids, and hygienic fluid routing, this union fits seamlessly into Swagelok® alternative ompression setups. It provides repeatable, leak-tight sealing in applications that demand precise fluid control and regular maintenance access.

Whether you’re installing gas or liquid lines in a lab, pressure system, or automated process loop, the SU-12 delivers reliable sealing, clean alignment, and long-term performance.
