Parker 10743-4-4 Female Swivel Hose Fitting 1/4 in Npsm

Product Description

The PARKER 10743-4-4 is a straight female swivel fitting designed for hydraulic hose assemblies in industrial and mobile fluid power applications. Manufactured from steel, this Series 43 fitting accepts a 1/4 inch (0.25 inch ID, hose size 4) hose and connects via NPSM threaded engagement. The swivel design allows the hose to be positioned without twisting during assembly, reducing installation stress and simplifying routing in tight plumbing layouts. With an overall length of 1.74 inches, it is a compact, direct-replacement component suited for use by hydraulic technicians and fluid power mechanics working on pressure lines and return circuits.

This fitting is intended for use in hydraulic systems where a female swivel termination is required at a hose end. The NPSM thread standard makes it compatible with standard straight mechanical pipe thread ports. Its straight shape suits inline connections where angular fittings are not required. Licensed hydraulic technicians and industrial maintenance professionals install this fitting type during hose fabrication and system assembly across manufacturing, construction equipment, and fluid handling environments.

Installation Notes

Installation should be performed by a qualified hydraulic technician familiar with fluid power hose assembly practices. Depressurize and isolate the hydraulic circuit completely before disconnecting or installing any fittings. Use appropriate hose crimping or reusable fitting assembly equipment per the hose manufacturer's specifications. Inspect threads and sealing surfaces for damage before assembly and do not overtighten, as NPSM threads rely on mechanical engagement rather than a tapered seal.
