Parker FEM-501-8FP Female Pipe Thread Hydraulic Coupler 1/2 in

Product Description

The PARKER FEM-501-8FP is a no-lock female pipe thread hydraulic coupler designed for use in high-pressure hydraulic systems. Built from steel with an NPSF threaded connection, this straight-body coupler handles a maximum working pressure of 5000 psi and supports flow rates up to 12.00 GPM. It measures 2.96 inches in overall length with a 1/2-inch body diameter and accepts a 1/2-14 thread size. Rated to ISO 16028, it is installed by hydraulic technicians and equipment mechanics working on mobile machinery, skid loaders, and hydraulic tool circuits where a compact, reliable female pipe thread coupler is required.

This coupler is intended for hydraulic tool applications and skid loader attachments operating within its rated pressure and flow envelope. The no-lock design allows for straightforward connection and disconnection in service environments where positive locking mechanisms are not required. Its threaded NPSF interface makes it compatible with standard female pipe thread hydraulic circuitry in both mobile and stationary equipment contexts. It is suited for residential and light commercial equipment service as well as heavier industrial mobile equipment maintenance.

Key Features

• Maximum working pressure of 5000 psi for demanding hydraulic circuit service
• Maximum flow rate of 12.00 GPM supports high-volume hydraulic tool operation
• Steel construction provides durability in harsh mobile equipment environments
• NPSF threaded connection type for secure, leak-resistant pipe thread engagement
• Straight body shape and compact 2.96-inch length simplify routing in tight spaces
• Conforms to ISO 16028 for standardized hydraulic quick coupler interoperability

Compatibility

Designed for use with hydraulic tools and skid loader attachments. Suitable as an OEM-style replacement or new-installation female pipe thread coupler in hydraulic circuits with 1/2-inch, 1/2-14 NPSF threaded connections rated to ISO 16028.

Installation Notes

Installation should be performed by a qualified hydraulic technician or equipment mechanic. Depressurize the hydraulic system fully and relieve any stored pressure before removing or installing couplers. Apply appropriate thread sealant to NPSF threads per the equipment manufacturer's specification, and inspect threads for damage before assembly. Torque fittings to the equipment manufacturer's published specification using calibrated tooling.
