Parker 71-3N6-6F Hydraulic Hose Valve Fitting 3/8 in 10000 Psi

Product Description

The PARKER 71-3N6-6F is a straight hydraulic hose valve fitting designed for high-pressure fluid control in industrial and heavy-duty hydraulic systems. Built from steel with a 3/8-inch NPTF threaded connection, this fitting is rated to a maximum working pressure of 10,000 psi and handles operating temperatures from -35 degrees F to 250 degrees F. Its straight geometry and threaded shaft type make it a reliable choice for securing hose-to-valve connections in demanding environments. Licensed hydraulic technicians and industrial mechanics install this fitting as part of Series 71 Parker hydraulic assemblies where leak-free, high-integrity connections are required.

This fitting is suited for industrial hydraulic lines and off-shore drilling applications where pressure integrity and material durability are critical. The 3/8-inch hose size and 0.375-inch coupler diameter make it appropriate for mid-range hydraulic circuits operating at full rated pressure. It is typically installed inline between a hydraulic hose and a valve body, providing a secure threaded interface that withstands both pressure spikes and temperature cycling encountered in mobile and stationary hydraulic equipment.

Installation Notes

Installation should be performed by a qualified hydraulic technician or industrial mechanic. Always depressurize and bleed the hydraulic system fully before removing or installing any fitting. Inspect threads and sealing surfaces for damage before assembly, and apply appropriate thread sealant compatible with the hydraulic fluid in use. Follow applicable industry standards and equipment manufacturer torque guidance for NPTF threaded fittings.
