Parker 71-3C12-12F Hydraulic Hose Valve Fitting 3/4 in 7500 Psi

Product Description

The PARKER 71-3C12-12F is a straight hydraulic hose valve fitting designed for high-pressure fluid power applications. Built from steel with a 3/4-inch NPTF threaded connection, it delivers a maximum working pressure of 7,500 psi and handles temperatures from -35 degrees F to 250 degrees F. The straight profile keeps plumbing compact in tight installations. This fitting is installed by hydraulic system technicians and industrial maintenance professionals working on fixed or mobile hydraulic circuits.

The 71-3C12-12F fits 3/4-inch hydraulic hose lines and is suited for industrial hydraulic systems and off-shore drilling equipment. The NPTF thread form creates a pressure-tight mechanical seal without relying solely on thread sealant, making it appropriate for high-cycle, high-pressure service environments. Its 3.05-inch overall length should be confirmed against routing clearances before installation.

Installation Notes

Hydraulic fittings of this type are installed by qualified hydraulic technicians or industrial maintenance personnel. Depressurize and lock out the hydraulic system completely before removing or installing any fitting. Inspect threads for damage before assembly and apply thread sealant only as required by the NPTF connection specification and the system manufacturer's guidelines. Torque to the system designer's specification using calibrated tooling.
