Parker 71-3N16-16F Hydraulic Hose Valve Fitting 7500 Psi

Product Description

The PARKER 71-3N16-16F is a straight hydraulic hose valve fitting designed for high-pressure fluid transfer in industrial and offshore hydraulic systems. Built from steel with a threaded NPTF connection, it handles working pressures up to 7,500 psi and temperatures from -35 degrees F to 250 degrees F. The fitting measures 3.23 inches in overall length and accepts a 1-inch hose size with a 1-inch thread size. It is installed by hydraulic technicians and maintenance mechanics working on high-demand fluid power circuits where a secure, leak-free connection is critical.

This fitting is suited for industrial hydraulic lines and offshore drilling applications where pressure integrity and material durability are required. The straight configuration simplifies in-line hose-to-valve connections in tight plumbing runs. Part of the Parker Series 71 product family, it is a standard catalog component stocked for both maintenance and new-build hydraulic assemblies. Typical installations include high-cycle hydraulic circuits found in heavy equipment, industrial machinery, and offshore drilling rigs.

Key Features

• Maximum working pressure of 7,500 psi for demanding hydraulic service
• Steel construction for durability in industrial and offshore environments
• NPTF threaded connection type for a pressure-tight, leak-resistant seal
• Straight shape simplifies in-line hose-to-valve routing
• Operating temperature range of -35 degrees F to 250 degrees F
• Overall length of 3.23 inches with 1-inch coupler size

Compatibility

Designed for use with industrial hydraulic lines and offshore drilling fluid power systems as stated by the manufacturer. Suitable for 1-inch hydraulic hose assemblies requiring an NPTF threaded valve fitting interface.

Installation Notes

Installation should be performed by a qualified hydraulic technician or millwright familiar with high-pressure fluid power systems. Depressurize and lock out the hydraulic circuit completely before removing or installing any fitting. NPTF threads are self-sealing by design, but inspect threads carefully for damage before assembly to ensure a proper pressure-tight connection. Follow applicable industry standards and equipment manufacturer torque guidelines when making up threaded hydraulic connections.
