Parker CPIFF-3P-5 Hydraulic Check Valve 5000 Psi

Product Description

The PARKER CPIFF-3P-5 is a straight hydraulic hose check valve designed to allow one-directional fluid flow while preventing backflow in hydraulic lines. Built from steel with a threaded NPSF connection, this valve is rated for a maximum working pressure of 5000 psi and an overall length of 2.6 inches. It fits a 3/8-inch hose size and handles temperatures from -15 degrees F to 400 degrees F, making it suitable for demanding hydraulic system environments. This valve is part of the CPIFF series and is typically installed by hydraulic system technicians and industrial maintenance professionals.

This check valve is used in hydraulic hose assemblies where backflow prevention is required to protect pumps, actuators, or other downstream components. Its straight body profile suits inline installations in tight plumbing runs. The 3/8-inch thread size and NPSF thread form make it compatible with standard American straight-thread hydraulic fittings. It is commonly found in mobile equipment, industrial machinery, and hydraulic power units operating within its rated pressure and temperature range.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Always depressurize and de-energize the hydraulic system completely before removing or installing any valve or fitting. Use appropriate thread sealant compatible with hydraulic fluid and verify that all connections are tightened to fitting manufacturer specifications. Inspect the hose assembly for wear or damage before returning the system to service.
