Parker S71-3N12-12F Hydraulic Hose Valve Fitting 3/4 in 5000 Psi

Product Description

The PARKER S71-3N12-12F is a stainless steel hydraulic hose valve fitting rated for operating pressures up to 5,000 psi. Designed for 3/4-inch thread connections, this fitting serves as a termination and flow-control interface within high-pressure hydraulic lines. The stainless steel construction provides corrosion resistance in demanding fluid-power environments. It handles a temperature range of -35 degrees F to 250 degrees F, making it suitable for both cold-start and elevated-temperature hydraulic system conditions. Hydraulic system technicians and industrial maintenance professionals are the primary installers of this component.

This valve fitting is intended for use in hydraulic hose assemblies where a secure, leak-resistant connection is required at a valve port. Applications include mobile hydraulic equipment, industrial machinery, and fluid-power systems operating at pressures up to 5,000 psi. The 3/4-inch thread size accommodates standard hydraulic hose and valve port configurations found in a wide range of commercial and industrial installations. Stainless steel construction makes it a practical choice in environments where moisture, chemicals, or corrosive fluids are present.

Installation Notes

Installation should be performed by a qualified hydraulic systems technician. Always depressurize and de-energize the hydraulic system fully before removing or installing any fitting. Use appropriate thread sealant rated for hydraulic fluid compatibility and follow torque guidance from the equipment manufacturer. Inspect mating surfaces and port threads for damage before assembly to ensure a leak-free connection.
