Parker 10643-10-10 Female Jic 37 Deg Swivel Fitting

Product Description

The PARKER 10643-10-10 is a straight, female JIC 37-degree swivel fitting designed for use with hydraulic hose assemblies in high-pressure fluid power systems. Built from steel with a threaded connection type, this fitting accepts a 5/8-inch thread size and is compatible with hoses having a 0.625-inch inside diameter. With an overall length of 2.93 inches, it is a compact, line-service component used by hydraulic technicians and industrial maintenance professionals to terminate hose runs with a reliable JIC swivel interface. The Series 43 designation places it within a well-established Parker fitting family suited for demanding hydraulic applications.

This fitting is used in hydraulic plumbing installations across industrial, mobile, and agricultural equipment where JIC 37-degree flare connections are specified. The swivel design allows the hose to be positioned without twisting during assembly, reducing installation stress on the hose. It is appropriate for both shop-built and field-repaired hose assemblies where a female JIC termination is required on a straight-body end. Licensed hydraulic technicians and industrial pipefitters are the typical installers.

Installation Notes

Installation should be performed by a qualified hydraulic technician familiar with JIC flare fitting assembly procedures. Depressurize and bleed the hydraulic system fully before removing any existing fittings or hose ends. The swivel feature allows the body to rotate during hand-tightening to align the hose without inducing twist — ensure the hose is not under torsional load before final tightening. Follow the equipment manufacturer's specifications and applicable fluid power standards for final assembly torque and system pressure testing.
