Parker CPIFF-8P-5 Hydraulic Check Valve 5000 Psi

Product Description

The PARKER CPIFF-8P-5 is a straight hydraulic hose check valve designed to allow one-directional fluid flow while preventing backflow in hydraulic systems. Built from steel and featuring a threaded NPSF connection, this valve handles a maximum working pressure of 5000 psi and operates across a wide temperature range of -15 degrees F to 400 degrees F. With an overall length of 4.78 inches and a 1-inch hose size, it is sized for mid-to-large hydraulic lines. It is part of the CPIFF series and is installed by hydraulic system technicians in mobile equipment, industrial machinery, and fluid power circuits.

This check valve is suited for applications requiring reliable backflow prevention in high-pressure hydraulic circuits. Its straight geometry and threaded NPSF connection make it compatible with standard hydraulic hose assemblies in industrial and mobile hydraulic systems. The steel construction supports demanding duty cycles where pressure spikes and temperature extremes are common. Typical installation scenarios include hydraulic power units, cylinder circuits, and pump outlet lines where preventing reverse flow is critical to system integrity.

Compatibility

Designed as an OEM-style replacement or new-install component for 1-inch hydraulic hose assemblies using NPSF threaded connections in high-pressure hydraulic circuits rated to 5000 psi.

Installation Notes

Installation should be performed by a qualified hydraulic systems technician. Depressurize and de-energize the hydraulic system completely before removing or installing any valve components. Verify thread type and torque fittings to the system manufacturer specifications using appropriate hydraulic fitting tools. Ensure flow direction markings on the valve body are oriented correctly before final assembly.
