Parker 1J943-12-12 Female Seal-lok Swivel Elbow 0.75 in

Product Description

The PARKER 1J943-12-12 is a female Seal-Lok swivel elbow fitting designed for high-pressure hydraulic hose assemblies. Machined from steel and configured at a 90-degree angle, this fitting connects a 3/4-inch (0.75-inch ID, hose size 12) hydraulic hose to a port using a Seal-Lok threaded interface. The swivel design allows the hose to be positioned without twisting during assembly, reducing installation strain and maintaining proper routing in tight hydraulic circuits. It is part of Parker Series 43 and is intended for use by hydraulic system technicians, equipment mechanics, and fluid power specialists working on industrial or mobile hydraulic applications.

This fitting is suited for hydraulic hose assemblies found in industrial machinery, mobile equipment, and fluid power systems where a 90-degree directional change is required at the hose-to-port connection. The Seal-Lok face-seal thread design provides a reliable, leak-resistant connection in high-pressure hydraulic circuits. It is appropriate for both OEM assembly and field repair work on systems where Parker 300, 400, 700, and 800 series hoses are specified.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and isolate the hydraulic circuit fully before disconnecting or assembling any hose fittings. Verify thread engagement and face-seal seating per the fitting manufacturer guidelines before returning the system to service. Consult applicable hydraulic system schematics to confirm correct hose routing and swivel orientation prior to final torque.
