Parker NS-371-6FP Female Pipe Rigid Coupler Fitting 3/8 in

Product Description

The PARKER NS-371-6FP is a female pipe rigid coupler fitting designed for hydraulic hose assemblies in demanding fluid power applications. Built from steel with a straight configuration, it accepts a 3/8-inch hose and uses NPSF threaded connection at 3/8-18 thread size. The fitting is rated to a maximum working pressure of 2500 psi and supports flow rates up to 10 gallons per minute, making it suitable for moderate- to high-pressure hydraulic circuits. Licensed plumbers, hydraulic technicians, and equipment mechanics install this type of fitting when assembling or servicing hydraulic lines that terminate at a fixed female pipe port.

This fitting is used in applications involving hydraulic hand tools, mining equipment, and utility equipment where a secure, rigid threaded female pipe connection is required. The NPSF thread form provides a pressure-tight mechanical seal in hydraulic circuits. Its straight body geometry simplifies routing in tight installations where a swivel or angled fitting is not needed. The compact overall length of 2.1 inches minimizes dead volume and keeps the assembly profile low in space-constrained equipment bays.

Key Features

• NPSF threaded connection ensures a pressure-tight fit in female pipe port applications
• Maximum working pressure of 2500 psi suits moderate- to high-pressure hydraulic systems
• Maximum flow rate of 10 gallons per minute for typical hydraulic hand tool and utility circuits
• Steel construction provides durability in mining and utility service environments
• Straight body shape with 2.1-inch overall length keeps installation compact
• 3/8-inch hose size and 3/8-18 thread size match common hydraulic line and port standards

Compatibility

Designed for use with hydraulic hand tools, mining equipment, and utility equipment requiring a 3/8-inch female pipe rigid coupler fitting with NPSF thread in the Parker NS series.

Installation Notes

Installation is typically performed by a licensed hydraulic technician or equipment mechanic. Depressurize and bleed the hydraulic system fully before removing or installing any fitting. Inspect the mating port threads for damage or contamination before assembly. Do not exceed the rated working pressure of 2500 psi in service.
