Parker 71-3C8-8F Hydraulic Hose Valve Fitting 10000 Psi

Product Description

The PARKER 71-3C8-8F is a straight hydraulic hose valve fitting designed for high-pressure fluid control in industrial and heavy-duty hydraulic systems. Built from steel with a 1/2-inch NPTF threaded connection, this fitting handles a maximum working pressure of 10,000 psi and operates reliably across a temperature range of -35 degrees F to 250 degrees F. At 2.77 inches in overall length, it provides a compact, straight-line connection for hose-to-valve interfaces. It is installed by hydraulic system technicians and pipefitters working on high-pressure lines where thread integrity and pressure retention are critical.

This fitting is suited for use on industrial hydraulic lines and off-shore drilling applications where dependable high-pressure performance is required. The NPTF thread form provides a pressure-tight seal without relying solely on a separate sealer, making it appropriate for demanding hydraulic circuits. The straight configuration simplifies routing in applications where hose and port alignment is already in line. It is sold individually and is part of the Parker Series 71 valve fitting family.

Installation Notes

Installation should be performed by a qualified hydraulic technician or pipefitter. Depressurize and isolate the hydraulic circuit completely before removing or installing any fitting. NPTF threads require proper thread engagement to achieve a seal — inspect threads for damage before installation and apply appropriate thread sealant per system requirements. Follow all applicable safety standards and equipment manufacturer guidelines for hydraulic system service.
