Parker 13743-5-4 Hydraulic Hose Fitting 45 Degree Elbow

Product Description

The PARKER 13743-5-4 is a 45-degree elbow hydraulic hose fitting designed to connect hydraulic hoses to ports and adapters in high-pressure fluid systems. Built from steel with a Female JIC threaded connection, this fitting accommodates a 0.25-inch (1/4 inch) hose inside diameter and uses a 1/2-20 thread size. It belongs to Parker's Series 43 fitting line. The 45-degree elbow geometry allows routing in confined spaces where straight fittings cannot clear surrounding components. Licensed hydraulic technicians and industrial maintenance professionals install this fitting during hose assembly, system repair, or equipment rebuild.

This fitting is intended for use in mobile hydraulic equipment, industrial machinery, and fluid power systems where a 45-degree hose-end connection is required. The Female JIC threaded interface is widely used in hydraulic circuits across agricultural, construction, and manufacturing equipment. The compact elbow profile helps manage hose routing away from heat sources, sharp edges, and moving parts in tight equipment bays.

Installation Notes

Installation should be performed by a qualified hydraulic technician familiar with fluid power system assembly. Depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. Use appropriate wrenching flats and avoid over-tightening JIC threaded connections, as proper flare-seat engagement determines sealing — thread sealant is not used on JIC fittings. Follow system OEM torque guidelines and applicable fluid power standards during reassembly.
