Construction Details

The CPI™ single-ferrule design creates a spring-loaded sealing effect that maintains constant tension between the fitting body and nut, helping ensure long-term leak-tight performance.

Unlike conventional compression fittings, the ferrule design transmits make-up forces axially rather than radially, minimizing tubing stress and preserving tubing integrity during installation and remakes.

Manufactured from corrosion-resistant 316 stainless steel, this fitting is suitable for demanding industrial and instrumentation applications where reliability is critical.
