Parker 10643-6-4 Hydraulic Hose Fitting Sae 37 Flare

Product Description

The PARKER 10643-6-4 is a straight, threaded hydraulic hose fitting designed to connect a hose end to an SAE 37-degree flare port. Built from steel with a female JIC connection, this fitting serves as a transition between a hose assembly with a 0.25-inch inside diameter and a 3/8-inch threaded port. It measures 2.05 inches in overall length. Hydraulic technicians and fluid power mechanics install this fitting in high-pressure hydraulic circuits where a reliable, leak-free seal at the JIC flare seat is required. The straight body simplifies routing in space-constrained installations.

This fitting is suited for use in mobile hydraulic equipment, industrial fluid power systems, and hydraulic power units where Parker hose assemblies terminate at threaded ports. It is designed for use with a specific range of Parker hose series listed in the compatibility section. Straight-body JIC fittings like this one are commonly installed at pump outlets, valve manifolds, cylinder ports, and inline tool connections wherever SAE 37-degree flare interfaces are specified.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic. Depressurize and isolate the hydraulic circuit completely before disconnecting or assembling any fittings. Inspect the flare seat and threads for damage or contamination before assembly, and ensure the mating port threads and flare geometry match the fitting specifications. Do not overtighten; follow the applicable system design specifications and industry standard practices for JIC flare connections.
