Parker 1J943-4-4 Female Seal-lok Swivel Elbow 1/4 in

Product Description

The PARKER 1J943-4-4 is a female Seal-Lok swivel elbow fitting designed for hydraulic hose assemblies. Constructed from steel, this fitting features a 90-degree elbow geometry and a threaded Seal-Lok connection type that provides a reliable, leak-resistant interface between hose and port. It is sized for 0.25-inch inside diameter hose (hose size 4) with a 1/4-inch thread size. The swivel design allows the fitting to rotate during assembly, reducing torsional stress on the hose and simplifying routing in tight spaces. Parker Series 43 construction meets ISO 12151-1 standards. Licensed hydraulic system technicians and fluid power specialists are the primary installers of this component.

This fitting is intended for use in industrial and mobile hydraulic systems where a 90-degree directional change at the hose-to-port connection is required. It is compatible with a broad range of Parker hydraulic hoses, including the 187, 302, 304, 387, 422, 424, 426, 436, 471TC, 471ST, 472TC, 482TC, 482ST, 487, 722, 787, 797, and 881 series hose lines, as well as TC and ST variants where listed. Typical applications include construction equipment, agricultural machinery, and industrial hydraulic circuits requiring a compact elbow termination.

Key Features

• Female Seal-Lok swivel connection provides leak-resistant, torque-free assembly at the port interface

• Steel construction suited for high-pressure hydraulic service environments
• Threaded connection type compatible with standard Seal-Lok port configurations
• Meets ISO 12151-1 for hydraulic fluid power hose fittings
• Swivel body reduces hose twist during make-up and in service

Compatibility

Compatible with Parker hydraulic hoses 187 (TC, ST), 302, 304, 387 (TC, ST), 422, 424, 426, 436, 471TC, 471ST, 472TC, 482TC, 482ST, 487 (TC, ST), 722 (TC, ST), 787 (TC, ST), 797 (TC, ST), and 881 series hoses.

Installation Notes

Installation should be performed by a qualified fluid power technician or hydraulic system mechanic. Depressurize and isolate the hydraulic circuit fully before disconnecting any fittings or hose assemblies. Torque the fitting to the port using the proper flats-on-flats (FOF) method per the fitting manufacturer guidelines — do not use hose torque to drive the swivel nut. Verify thread engagement and inspect for leaks after system re-pressurization. California Proposition 65 warning applies to this product.
