Parker S71-3C12-12F Hydraulic Valve Fitting 3/4 in 5000 Psi

Product Description

The PARKER S71-3C12-12F is a stainless steel hydraulic hose valve fitting rated for 5,000 psi working pressure. It is designed for use in high-pressure hydraulic lines where a valve-type connection point is required. With a 3/4 inch thread size and a temperature range of -35 degrees F to 250 degrees F, this fitting suits demanding fluid-power applications in industrial, mobile, and commercial hydraulic systems. Licensed hydraulic technicians and fluid-power specialists install this type of fitting when building or servicing high-pressure hose assemblies.

This fitting is well suited to hydraulic circuits operating in environments with wide temperature swings or exposure to corrosive media, where stainless steel construction provides the corrosion resistance that carbon steel fittings cannot. Typical installation scenarios include industrial machinery, mobile equipment hydraulic lines, and any system where a valve fitting is needed at a 3/4 inch port. It ships as a single unit and is available in single-piece quantities to support repair and maintenance work.

Key Features

• 5,000 psi pressure rating suitable for high-pressure hydraulic circuits
• Stainless steel construction for corrosion resistance in harsh environments
• 3/4 inch thread size for compatibility with standard hydraulic hose ends and valve ports
• Operating temperature range of -35 degrees F to 250 degrees F
• Valve fitting design allows controlled connection and disconnection of hydraulic lines

Compatibility

Designed as an OEM-style replacement or service fitting for high-pressure hydraulic hose assemblies requiring a 3/4 inch valve-type fitting rated to 5,000 psi.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid-power specialist. Depressurize and fully bleed the hydraulic system before removing or installing any fittings. Use appropriate thread sealant or fittings tape as required by the system design, and verify thread type and pitch before installation to avoid cross-threading. Follow applicable industry standards and equipment manufacturer guidelines when assembling hydraulic lines.
