Parker 71-3C16-16F Hydraulic Hose Valve Fitting 7500 Psi

Product Description

The PARKER 71-3C16-16F is a straight hydraulic hose valve fitting rated for 7,500 psi maximum working pressure. Built from steel with a threaded NPTF connection, it is designed for demanding fluid-power applications where leak-free, high-pressure performance is required. The fitting accepts a 1-inch hose size and features a 1-inch thread size with a 1-inch coupler interface. At 3.32 inches overall length, it installs directly into industrial hydraulic lines and related assemblies. Licensed hydraulic technicians and pipefitters are the typical installers for this type of fitting.

This fitting is suited for industrial hydraulic lines and off-shore drilling applications where high-pressure steel fittings with NPTF threads are required. The straight body geometry keeps routing straightforward in tight manifold and valve-block configurations. Its temperature range of -35 degrees F to 250 degrees F makes it viable across a broad range of operating environments, from cold-climate field equipment to heated industrial process systems.

Key Features

• 7,500 psi maximum working pressure for high-demand hydraulic circuits
• Steel construction for durability in industrial and off-shore environments
• NPTF threaded connection for a pressure-tight, tapered-thread seal
• Straight body profile simplifies routing and valve-block installation
• Operating temperature range: -35 degrees F to 250 degrees F
• Parker Series 71 design for consistent dimensional and pressure-rating standards

Compatibility

Rated for use with industrial hydraulic lines and off-shore drilling equipment. Designed as an OEM-style hydraulic hose valve fitting for systems requiring 1-inch NPTF straight fittings at 7,500 psi working pressure.

Installation Notes

Installation should be performed by a qualified hydraulic technician or pipefitter familiar with high-pressure fluid-power systems. Always depressurize and isolate the hydraulic circuit completely before removing or installing any fitting. NPTF tapered threads rely on thread-form interference for sealing — inspect threads for damage before assembly and apply thread sealant per the system designer's specification. Verify that all connected components are rated for at least 7,500 psi before returning the system to service.
