Parker PX-00031 Female Jic 37 Swivel Fitting 0.625 in

Product Description

The PARKER PX-00031 is a straight female JIC 37-degree swivel fitting designed for hydraulic hose assemblies requiring a reliable, leak-resistant threaded connection. Constructed from brass, this fitting accepts a 5/8-inch (0.625-inch ID) hydraulic hose and terminates with a 1-1/16-12 UN female JIC swivel thread. The overall length is 2.15 inches. The swivel design allows the fitting end to rotate during installation, reducing hose twist and simplifying assembly in tight or awkward plumbing runs. This fitting is part of Parker's 91N series and is installed by hydraulic system technicians, millwrights, and fluid-power specialists working on mobile or stationary hydraulic circuits.

This fitting is suited for hydraulic hose assemblies where a straight, female JIC 37-degree flare connection is required at the hose end. Typical applications include industrial machinery, mobile equipment hydraulics, and fluid-power systems that use standard JIC 37-degree flare fittings. The brass construction makes it appropriate for compatible hydraulic fluid services where brass is an accepted material. This part is sold in packages of five units, making it practical for service shops and assembly operations that build or repair multiple hose assemblies.

Compatibility

Designed for use with 5/8-inch ID (size 10) hydraulic hose assemblies requiring a straight female JIC 37-degree swivel fitting with a 1-1/16-12 thread. Verify hose and port specifications before installation to confirm fitment.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid-power specialist. Depressurize and isolate the hydraulic circuit completely before disconnecting or replacing any fitting. Inspect the JIC 37-degree flare seat on both the fitting and the mating port for nicks or deformation before assembly, as surface damage will prevent a proper seal. Hand-tighten the swivel nut before applying final wrench torque in accordance with the equipment manufacturer's specifications and applicable fluid-power standards.
