Parker 1JS43-4-6 Female Seal-lok Swivel Fitting 3/8 in

Product Description

The PARKER 1JS43-4-6 is a female Seal-Lok swivel short fitting designed for use with 3/8-inch hydraulic hose assemblies. Constructed from steel, it uses Parker's Seal-Lok face-seal connection method, which provides a leak-free joint by compressing an O-ring against a flat face rather than relying on thread deformation. The swivel design allows the hose end to rotate during installation, reducing torsional stress on the hose. This fitting is a standard component in hydraulic plumbing work and is installed by hydraulic system technicians, industrial maintenance mechanics, and mobile equipment technicians.

This fitting is suited for hydraulic systems where a reliable, high-integrity face-seal connection is required at a hose termination point. The short-body configuration is used where space is limited around ports or manifolds. Typical applications include mobile hydraulic equipment, industrial machinery, and fluid power circuits requiring dependable swivel end connections on 3/8-inch hose assemblies. Sold in a package quantity of four.

Installation Notes

Installation should be performed by a qualified hydraulic technician familiar with face-seal fitting assembly procedures. Depressurize and isolate the hydraulic circuit completely before disconnecting or installing any fittings. Inspect the O-ring seating surface and replace the O-ring if damaged before torquing the fitting. Follow the applicable fluid power system standards and equipment manufacturer guidelines for final assembly.
