Parker 71-3N8-8F Hydraulic Valve Fitting 10000 Psi 1/2 in

Product Description

The PARKER 71-3N8-8F is a straight hydraulic hose valve fitting designed for high-pressure fluid control in industrial hydraulic systems. Built from steel with a threaded NPTF connection, this fitting handles a maximum working pressure of 10,000 psi and operates across a temperature range of -35 degrees F to 250 degrees F. The 1/2 inch hose size and 1/2 inch thread size make it a direct, reliable connection point in demanding hydraulic circuits. Licensed hydraulic technicians and pipefitters install this type of fitting during system assembly, maintenance, and pressure-line repair on industrial and offshore equipment.

This fitting is suited for industrial hydraulic line applications and offshore drilling operations. The Series 71 design from PARKER delivers consistent sealing performance in straight-run configurations where a valve fitting interface is required. The NPTF thread form creates a pressure-tight mechanical seal without relying solely on thread sealant. It is appropriate for use in both new hydraulic system builds and replacement scenarios on existing high-pressure lines.

• Steel construction for durability in industrial and offshore environments
• NPTF threaded connection provides a pressure-tight mechanical seal
• Straight shape simplifies inline installation and routing
• Operating temperature range of -35 degrees F to 250 degrees F
• Series 71 valve fitting with 1/2 inch hose and thread sizing

Compatibility

Designed for use with industrial hydraulic lines and offshore drilling applications as specified by the manufacturer. Verify hose size, thread size, and pressure rating against your system requirements before installation.

Installation Notes

Installation should be performed by a qualified hydraulic technician or pipefitter familiar with high-pressure fluid systems. Depressurize and fully isolate the hydraulic circuit before removing or installing any fittings. Inspect threads for damage before assembly and apply appropriate thread sealant per your system specifications if required by the application. Torque fittings according to your system engineering documentation and applicable industry standards.
