Parker CPI Stainless Steel Union Tee for Fractional Tube

Parker CPI™ Union Tee fittings provide a reliable method for connecting three equal-size fractional tubing lines in instrumentation and process systems. Designed with Parker's proven CPI™ single-ferrule compression technology, these fittings create leak-free connections while maintaining excellent vibration resistance and ease of assembly.

Manufactured from heat code traceable 316 stainless steel, Parker CPI™ Union Tees are engineered for demanding applications in chemical processing, power generation, analytical instrumentation, environmental systems, and other critical fluid handling installations.

Key Features

• Union tee design for connecting three equal-size tube runs
• Parker CPI™ single-ferrule compression connection technology
• Heat code traceable 316 stainless steel construction
• Leak-free sealing performance
• Excellent resistance to vibration and mechanical stress
• No tube twisting during installation
• Supports multiple remakes and maintenance cycles
• Compatible with thin-wall and heavy-wall tubing
• Designed for instrumentation and process control applications
• Available in multiple fractional tube sizes

Construction Details

The CPI™ single-ferrule design creates a spring-loaded sealing action that maintains constant tension between the fitting body and nut, helping ensure long-term sealing integrity under demanding operating conditions.

During assembly, axial ferrule movement eliminates tubing twist and minimizes stress on the tubing, preserving system integrity and reducing installation issues.

Precision-machined components provide reliable make-up, easy disassembly, and consistent remake performance throughout the service life of the fitting.

Material & Compatibility

Standard construction utilizes heat code traceable 316 stainless steel for corrosion resistance and durability in industrial service environments.

Suitable for use with a wide range of tubing materials and wall thicknesses when material compatibility with the process media is maintained.

Important Notes

This listing includes multiple Parker CPI™ Union Tee size variations with equal tube connections on all three ports.

Proper assembly procedures are critical to achieving leak-free performance and should follow Parker Instrumentation Products installation guidelines.

Pressure ratings depend on tubing size, wall thickness, material selection, and operating conditions. Consult Parker technical documentation for application-specific ratings.
