Parker 1JC43-4-6 Female Seal-lok Swivel Short Fitting 9200 Psi

Product Description

The PARKER 1JC43-4-6 is a female Seal-Lok swivel short fitting designed for hydraulic hose assemblies. It accepts a 3/8 inch (hose size 6) hose inside diameter and connects via a 9/16-18 threaded interface. The straight, swivel configuration allows the fitting to rotate during assembly, reducing hose twist and making tight routing easier. Rated at 9,200 psi maximum working pressure, this steel fitting meets the demands of high-pressure hydraulic circuits. It is installed by hydraulic system technicians and fluid power mechanics on mobile and industrial equipment. The overall length is 1.9 inches.

This fitting is suited for use in hydraulic hose assemblies where a Seal-Lok (O-ring face seal) termination is required at one end and a standard hose crimp or reusable connection is made at the other. The short-body swivel design is commonly used in space-constrained installations on construction equipment, agricultural machinery, and industrial power units. The straight shape allows direct in-line routing without angled adapters.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic. Depressurize and isolate the hydraulic circuit completely before disconnecting or installing any fittings. The Seal-Lok interface requires a clean, undamaged O-ring face seal surface and a properly seated O-ring to achieve a leak-free connection. Torque the fitting per the applicable system documentation and inspect for leaks before returning the system to service.
