Parker 10143-4-6 Male Rigid Hydraulic Hose Fitting

Product Description

The PARKER 10143-4-6 is a male rigid straight hydraulic hose fitting designed for high-pressure fluid conveyance in industrial and mobile hydraulic systems. Manufactured from steel with a male NPTF threaded connection, this fitting provides a pressure-tight seal at a maximum working pressure of 10,000 psi. It accepts a 3/8-inch (0.375-inch ID) hose and uses a 1/4-18 NPTF thread for connection to ports, valves, or manifolds. The overall length is 2.28 inches. Licensed hydraulic technicians and fluid power mechanics install this fitting during hose assembly and system plumbing on both stationary and mobile equipment.

This fitting belongs to Parker Series 43 and is rated for use across a wide range of Parker hydraulic hose lines. It is suited for industrial machinery, construction equipment, and other high-pressure hydraulic circuits requiring a reliable, leak-resistant threaded hose end. The straight body configuration makes it appropriate for installations where a direct inline connection is needed without angular offset. The 3/4-inch hex size allows standard wrench tightening during assembly.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic. Depressurize and bleed the hydraulic system fully before removing or installing any hose fittings. Use the 3/4-inch hex and an appropriate torque wrench to tighten to the fitting manufacturer's specified torque value for NPTF connections. Inspect the mating port threads and hose end for damage or contamination before assembly to ensure a leak-free seal.
