Parker S71-3C8-8F Hydraulic Hose Valve Fitting 5000 Psi

Product Description

The PARKER S71-3C8-8F is a straight hydraulic hose valve fitting designed for high-pressure fluid control in demanding industrial and offshore applications. Built from stainless steel with a threaded NPSF connection, it handles working pressures up to 5,000 psi and temperatures from -35 degrees F to 250 degrees F. The 1/2 inch hose size and 1/2 inch thread size make it a direct-connect solution for mid-range hydraulic line assemblies. It ships as a single unit and is installed by hydraulic system technicians and pipefitters working on industrial fluid power circuits.

This fitting is rated for use on industrial hydraulic lines and off-shore drilling systems where corrosion resistance and pressure integrity are critical. The stainless steel construction holds up in wet, chemically aggressive, or marine environments. The straight body geometry simplifies in-line installations where a 90-degree or angled adapter is not needed. At 2.77 inches overall length, it fits in compact manifold and valve block assemblies without excessive protrusion.

Key Features

• 5,000 psi maximum working pressure for high-demand hydraulic circuits
• Stainless steel construction resists corrosion in industrial and offshore environments
• NPSF threaded connection for secure, leak-resistant engagement
• Straight body profile supports direct in-line hose-to-valve connections
• Operating temperature range: -35 degrees F to 250 degrees F
• Compact 2.77 inch overall length suits tight valve block and manifold installations

Compatibility

Designed for use with industrial hydraulic lines and off-shore drilling fluid power systems requiring a 1/2 inch hose size, 1/2 inch NPSF threaded connection, and a maximum working pressure of 5,000 psi. 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. Use appropriate thread sealant compatible with stainless steel and hydraulic fluid media. Verify torque requirements with system engineering documentation and inspect for leaks before returning the system to full operating pressure.
