Parker CPIFF-4P-5 Hydraulic Check Valve 5000 Psi 1/2 Inch

Product Description

The PARKER CPIFF-4P-5 is a straight hydraulic hose check valve designed to allow one-directional flow while preventing backflow in hydraulic systems. Built from steel with a 1/2-inch NPSF threaded connection, this valve is rated for a maximum working pressure of 5,000 psi and an operating temperature range of -15 to 400 degrees F. At 3.25 inches in overall length, it is a compact inline component suited for high-pressure hydraulic circuits. Installation is handled by hydraulic technicians and fluid power specialists working on industrial and mobile equipment applications.

The CPIFF-4P-5 is suited for use in high-pressure hydraulic hose assemblies and plumbing circuits requiring reliable check valve function. The straight body configuration supports direct inline installation without the need for angled adapters. It is commonly used in mobile hydraulics, industrial machinery, and fluid power systems where 1/2-inch hose lines operate at or near 5,000 psi. The NPSF thread type is standard in North American hydraulic fittings and adapts readily to common port configurations found in these systems.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Before servicing, depressurize the hydraulic system fully and ensure all stored energy is released prior to disconnecting any lines. Use appropriate thread sealant compatible with hydraulic fluid and torque fittings per the equipment manufacturer's specifications. Verify flow direction markings on the valve body before completing the installation to ensure correct check valve orientation.
