Parker Tubing And Fittings

Tube Fitting,single Ferrule Compression Fitting – CPI™ Series


Parker CPI™ single ferrule compression tube fittings are designed as leak free connections for process, power, and instrumentation applications. These tube fittings utilize a single ferrule for easy make-up and excellent performance in vibration applications. The “spring loaded” effect of the single ferrule creates a constant tension between the fitting body and fitting nut.

CPI™ tube fitting are manufactured from heat code traceable 316 stainless steel. Other materials include 6Mo, Alloy 825, Alloy 625 and Alloy C-276. Straight fittings are machined from cold finished bar stock, while shaped bodies are machined from close grain forgings.

Features and Benefits:

  • Single Ferrule for easy makeup
  • Molybdenium Disulfide coated nuts for low torque make-up
  • Parker Suparcase™ ferrule for superior corrosion resistant
  • Hardened ferrules provide optimum performance
