Parker 71-3C6-6F Hydraulic Hose Valve Fitting 3/8 in 10000 Psi

Product Description

The PARKER 71-3C6-6F is a straight hydraulic hose valve fitting designed for high-pressure fluid control applications in industrial and off-shore environments. Built from steel with an NPTF threaded connection, it accepts a 3/8 inch hose and is rated to 10,000 psi maximum working pressure. The fitting measures 2.36 inches in overall length and handles temperatures from -35 degrees F to 250 degrees F. It belongs to Parker's Series 71 valve fitting line and is installed by hydraulic technicians and pipefitters working on high-pressure fluid power systems where a secure, leak-free threaded connection is required.

This fitting is suited for industrial hydraulic lines and off-shore drilling applications where sustained high-pressure performance and reliable sealing are critical. Its straight geometry simplifies in-line installations, and the NPTF thread form provides a pressure-tight mechanical seal without relying solely on a sealant compound. It is a direct-fit component for systems requiring a 3/8 inch hose connection at the valve interface.

Key Features

• 10,000 psi maximum working pressure for demanding hydraulic service
• NPTF threaded connection delivers a pressure-tight mechanical seal
• Steel construction provides durability in industrial and off-shore environments
• Straight configuration for straightforward in-line valve installations
• Operating temperature range of -35 degrees F to 250 degrees F
• 2.36 inch overall length in a compact, space-efficient profile

Compatibility

Designed for use with industrial hydraulic lines and off-shore drilling systems requiring a 3/8 inch NPTF threaded hose valve fitting rated to 10,000 psi.

Installation Notes

Installation should be performed by a qualified hydraulic technician or pipefitter familiar with high-pressure fluid power systems. Depressurize and isolate the hydraulic circuit completely before removing or installing any fitting. NPTF threads are designed to seal on the thread form itself; inspect threads for damage before assembly and follow applicable industry standards for thread engagement and the use of compatible thread sealants. Verify system pressure does not exceed the fitting's rated maximum working pressure before returning the circuit to service.
