Parker 71-3N16-20F Hydraulic Hose Valve Fitting 1-1/4 in 7500 Psi

Product Description

The PARKER 71-3N16-20F is a hydraulic hose valve fitting designed for high-pressure fluid control applications in industrial and mobile hydraulic systems. Constructed from steel, this fitting provides a robust connection point between hydraulic hose assemblies and valves, handling pressures up to 7,500 psi. It accepts a 1-1/4 inch thread size and operates across a temperature range of -35 degrees F to 250 degrees F, making it suitable for demanding service environments. Installation is handled by hydraulic system technicians and industrial maintenance professionals working on equipment where reliable, leak-free connections are critical.

This fitting is commonly used in industrial machinery, mobile equipment, and hydraulic power units where valve-to-hose connections must maintain integrity under sustained high pressure. It suits applications in manufacturing, construction, and heavy equipment sectors. The 1-1/4 inch thread size and 7,500 psi pressure rating position it for mid-to-high-pressure hydraulic circuits found in both stationary and mobile systems. One fitting is included per package.

Key Features

• Steel construction for high-strength, corrosion-resistant performance in hydraulic service
• 7,500 psi maximum pressure rating suitable for demanding hydraulic circuits
• 1-1/4 inch thread size for direct valve-to-hose connections
• Operating temperature range of -35 degrees F to 250 degrees F
• UNSPSC Code 40141734 for procurement and catalog classification

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic hose and valve assemblies requiring a 1-1/4 inch steel valve fitting rated to 7,500 psi.

Installation Notes

Installation should be performed by a qualified hydraulic technician or industrial maintenance professional. Always depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. Inspect threads and sealing surfaces for damage prior to assembly, and apply appropriate thread sealant or follow the fitting manufacturer's torque guidelines as specified in the system service documentation. Verify that the replacement fitting thread type and size match the existing valve port before installation.
