Parker 1JS43-4-4 Female Seal-lok Swivel Fitting 0.25 in

Product Description

The PARKER 1JS43-4-4 is a female Seal-Lok swivel fitting designed for hydraulic hose assemblies. It features a straight, threaded connection and is constructed from steel for durability in high-pressure hydraulic systems. With a hose inside diameter of 0.25 inches (hose size 4) and a 1/4-inch thread size, this fitting integrates into hydraulic lines requiring a leak-resistant Seal-Lok interface. The overall length is 2.07 inches (53 mm). Licensed HVAC, plumbing, and fluid-power technicians install this fitting when assembling or repairing hydraulic hose circuits.

This fitting is suited for use in industrial, mobile, and commercial hydraulic applications where a female swivel end connection is required on the hose side. The Seal-Lok design provides a face-seal connection that resists vibration-induced leakage. It is rated for compatibility with a broad range of Parker hydraulic hose series, making it a practical replacement or assembly component in high-pressure fluid-power systems.
