Construction Details

The CPI™ single ferrule design provides consistent sealing performance while minimizing tubing stress during installation. Make-up and remake forces are transmitted axially to the tubing, preventing twisting or distortion and allowing repeated disassembly and reassembly.

Precision-machined 316 stainless steel construction provides outstanding corrosion resistance and long service life in demanding industrial environments.

Suitable for use with a wide variety of compatible tubing materials and wall thicknesses when proper installation procedures are followed.

Important Notes

Working pressure depends on tubing material, wall thickness, temperature, and system design. Pipe thread connections, when present in other fitting styles, may become the limiting pressure factor.

Always verify compatibility between tubing material, fitting material, and process media before installation.
