Parker 10643-20-20 Female Sae 45 Swivel Fitting 1.25 in

Product Description

The PARKER 10643-20-20 is a female SAE 45-degree swivel fitting designed for use with hydraulic hose assemblies in demanding fluid-power applications. Built from steel with a straight, threaded connection profile, this fitting features a female JIC swivel end that allows rotational adjustment during assembly without twisting the hose. It carries a hose inside diameter of 1.25 inches (hose size 20) and an overall length of 3.94 inches (100 mm). The 1-1/4 inch thread size is compatible with standard SAE 45-degree flare hydraulic circuits. Hydraulic technicians and fluid-power mechanics install this fitting in mobile equipment, industrial machinery, and high-pressure plumbing systems where secure, leak-resistant hose termination is required.

This fitting is suited for use on hose size 20 (1-1/4 inch ID) hydraulic hose assemblies in both mobile and stationary hydraulic systems. It is rated for use with Parker hose series including 187, TC, ST, 302, 304, 387, 422, 424, 426, 436, 471TC, 471ST, 472TC, 482TC, 482ST, 487, TC, ST, 722, TC, ST, 787, TC, ST, 797, TC, ST, and 881 hoses. Typical applications include agricultural equipment, construction machinery, and industrial hydraulic power units where a reliable SAE 45-degree flare swivel termination is specified.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid-power mechanic familiar with SAE 45-degree flare fitting assembly procedures. Depressurize and isolate the hydraulic circuit fully before disassembly or installation of any fitting. Use appropriate thread sealant or verify dry-seal thread requirements per system specifications before torquing. Follow applicable hydraulic system safety standards and equipment manufacturer guidelines during assembly and system recommissioning.
