The PARKER 3JC82-4-4 is a female Seal-Lok swivel short fitting designed for hydraulic hose assemblies. It provides a leak-resistant O-ring face seal (ORFS) connection at the hose end, pairing a 4 mm hose size with a 9/16-18 SAE thread. Constructed from steel, this fitting is built to withstand the pressure demands typical of industrial and mobile hydraulic systems. The swivel design allows the fitting to rotate during installation, reducing hose twist and making assembly easier in tight or awkward routing situations. Licensed hydraulic technicians and fluid power specialists are the primary installers of this component.
This fitting is suited for hydraulic lines in industrial equipment, mobile machinery, and fluid power systems where an ORFS swivel termination is required. The short body profile makes it a practical choice in space-constrained plumbing layouts. The 1/4-inch body diameter and 9/16-18 thread size are commonly encountered in light- to medium-duty hydraulic circuits. It is sold individually and is appropriate for new hose builds as well as field repair applications.
Designed as a direct-fit Seal-Lok swivel short hydraulic hose fitting for 4 mm hose size applications with a 9/16-18 SAE thread interface, consistent with PARKER Seal-Lok ORFS fitting standards.
Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and isolate the hydraulic circuit completely before disconnecting or assembling any hose fittings. Inspect the O-ring sealing face for damage or contamination before assembly, and confirm the O-ring is properly seated. Tighten to the fitting manufacturer-specified flats from finger-tight per standard ORFS assembly practice; do not overtighten, as this can damage the O-ring seal face.
