Parker 1JC43-12-12 Female Swivel Hydraulic Hose Fitting

Product Description

The PARKER 1JC43-12-12 is a straight female swivel fitting designed for hydraulic hose assemblies in industrial and mobile hydraulic systems. Built from steel with a Seal-Lok face seal connection, it accepts hoses with a 0.75 inch inside diameter (hose size 12) and uses a 3/4 inch threaded connection. The swivel design allows the fitting to rotate during installation, reducing torsional stress on the hose and making routing easier in tight or angled plumbing configurations. Overall length is 2.68 inches. This fitting is installed by hydraulic technicians and fluid power mechanics assembling or replacing hose circuits on machinery, equipment, or mobile vehicles.

This fitting is suited for hydraulic hose assemblies in both industrial and mobile applications where a reliable, leak-resistant face seal connection is required. The Seal-Lok interface conforms to ISO 12151-1-SWSA, making it appropriate for medium- to high-pressure hydraulic circuits. It is commonly found in manufacturing equipment, construction machinery, and agricultural or fleet vehicle hydraulic systems where Parker Series 43 end fittings are specified.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic familiar with face seal fittings. Depressurize and bleed the hydraulic circuit fully before removing or installing any fittings. Inspect the Seal-Lok face seal surface and mating port for nicks or contamination before assembly. Follow the equipment manufacturer and Parker assembly instructions for proper torque values, as face seal fittings require specific torque to seat correctly without over-compression.
