Parker 10243-12-12 Hydraulic Hose Female Rigid Fitting

Product Description

The PARKER 10243-12-12 is a female rigid hydraulic hose fitting designed for secure, leak-resistant connections in high-pressure hydraulic systems. Built from steel with a straight, threaded NPTF configuration, this fitting accepts a 3/4-14 thread and connects to hoses with a 0.75-inch inside diameter (hose size 12). Overall length is 2.72 inches. The NPTF thread form creates a pressure-tight seal on the threads themselves, reducing reliance on sealant tape in many applications. Hydraulic mechanics and fluid power technicians install this fitting as part of hose assemblies on mobile and industrial equipment.

This fitting is suited for hydraulic hose assembly work in industrial, agricultural, construction, and mobile equipment applications. It is rated for use with a wide range of Parker hose series, making it a practical stock item for shops that build or repair hydraulic lines. The straight geometry simplifies routing in tight or direct-line installations where angled fittings are not required.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic. Depressurize and isolate the hydraulic circuit completely before disassembling any hose or fitting. Use a properly sized open-end or flare-nut wrench on the 1-1/4 inch hex to avoid rounding. Inspect threads and hose ends for damage before assembly, and verify torque and system pressure ratings against equipment specifications before returning the system to service.
