Parker S71-3N8-8F Hydraulic Hose Valve Fitting 5000 Psi

Product Description

The PARKER S71-3N8-8F is a straight hydraulic hose valve fitting engineered 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 operating temperatures from -35 degrees F to 250 degrees F. The straight body profile keeps plumbing layouts compact and clean. Licensed hydraulic technicians and pipefitters working on industrial hydraulic lines, offshore drilling equipment, and related high-pressure systems will find this fitting a direct-fit solution in Parker Series 71 configurations.

This fitting is suited for industrial hydraulic lines and offshore drilling applications where corrosion resistance and reliable pressure containment are critical. The stainless steel construction holds up in wet, chemically aggressive, and saltwater-exposed environments typical of offshore and marine hydraulic systems. At 1/2 inch hose size and 1/2 inch thread size, it fits mid-range hydraulic circuits commonly found in both mobile and stationary high-pressure equipment.
