Parker 1J743-4-4 Female Jic 37 Deg Swivel Fitting

Product Description

The PARKER 1J743-4-4 is a female JIC 37-degree swivel fitting designed for hydraulic hose assemblies in fluid power systems. Built from steel with a Seal-Lok shaft type, this fitting features a 45-degree elbow geometry and a threaded connection type, giving technicians a secure, leak-resistant joint at hose termination points. It accepts a 1/4-inch hose inside diameter and is sold individually. Hydraulic system technicians and fluid power mechanics install this fitting when building or repairing hose assemblies that require a JIC 37-degree flare interface with rotational freedom during assembly.

This fitting is rated for use in industrial and mobile hydraulic applications where a 45-degree elbow orientation helps route hose lines around obstructions or into tight spaces. It is compatible with Parker hose series 187 TC, 187 ST, 302, 304, 387 TC, 387 ST, 422, 424, 426, 436, 471TC, 471ST, 472TC, 482TC, 482ST, 487 TC, 487 ST, 722 TC, 722 ST, 787 TC, 787 ST, 797 TC, 797 ST, and 881. The Seal-Lok design helps maintain a reliable seal under dynamic pressure conditions common in hydraulic circuits.

Compatibility

Compatible with Parker hose series 187 TC, 187 ST, 302, 304, 387 TC, 387 ST, 422, 424, 426, 436, 471TC, 471ST, 472TC, 482TC, 482ST, 487 TC, 487 ST, 722 TC, 722 ST, 787 TC, 787 ST, 797 TC, 797 ST, and 881 hoses with a 1/4-inch inside diameter.

Installation Notes

Installation should be performed by a qualified hydraulic technician familiar with fluid power system safety practices. Depressurize and bleed the hydraulic system completely before disconnecting any fittings or hose assemblies. Inspect the mating JIC 37-degree flare seat for damage or contamination before assembly and ensure threads are clean and free of debris. Tighten to the fitting manufacturer's standard procedure for JIC swivel connections; do not over-torque, as this can deform the flare seat and cause leaks.
