Parker 10543-6-6 Male Rigid Hydraulic Hose Fitting

Product Description

The PARKER 10543-6-6 is a male rigid straight fitting designed for hydraulic hose assemblies in industrial and mobile equipment applications. Machined from steel, this Series 43 fitting connects to hoses with a 0.375 inch (3/8 inch) inside diameter using a male SAE threaded interface. The straight configuration and threaded connection make it a standard choice for high-pressure hydraulic lines where a rigid, non-swivel end connection is required. With an overall length of 2.1 inches, the fitting integrates into tight plumbing layouts without added adapters. It is installed by hydraulic system technicians and maintenance professionals working on mobile machinery, industrial equipment, and fluid power circuits.

This fitting is suited for use in hydraulic hose assemblies on construction equipment, agricultural machinery, industrial presses, and mobile fluid power systems. The male SAE threaded end seats against a mating female port or adapter in the hydraulic circuit. The straight body keeps routing simple where a 90-degree or angled fitting is not needed. Its steel construction handles the mechanical demands of high-cycle hydraulic environments.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and fully isolate the hydraulic system before disassembling any hose or fitting. Inspect the mating port threads for damage before assembly and ensure the SAE thread engagement is clean and free of debris. Follow the equipment manufacturer and applicable fluid power industry standards for assembly torque and hose routing clearances.
