Wide Pressure Tolerances

With A-LOK® and CPI™ fittings for lower pressure, and MPI™ fittings for medium pressure from 6,000 to 15,000 psi, our compression fittings continue to offer high sealing integrity in increasingly demanding conditions. Phastite®, our ferrule-less, push-fit connector system, can be used in applications up to 20,000 psi.

Proven Anti-Corrosion

Parker's own case-hardening procedure – Suparcase® – produces a harder surface than nitriding without compromising corrosion resistance. Used in A-LOK, CPI and MPI fittings, Parker Suparcase ferrules provide superior corrosion resistance, longer service life, and lower extended cost due to fewer field changeouts. Parker Suparcase ferrules have been used for more than 30 years – with over 100,000,000 pieces in service without failure due to corrosion or cracking.

Vibration Resistance

Offering single ferrule, double ferrule and ferrule-less, permanent crimp connectors, Parker's broad range of high quality connector technologies offers multiple solutions to the problems of vibration.

• In MPI double ferrule fittings, a long tube support area improves resistance to vibration and line loads.
• CPI single ferrule fittings provide superior vibration performance due to the fittings' unique "bowing" action.
• Without threaded components, Phastite eliminates potential loosening problems in vibration applications.
