Midland Industries 650444 Straight Swivel Nut Jic Connector

Product Description

The MIDLAND INDUSTRIES 650444 is a straight swivel nut connector designed for hydraulic line assemblies requiring a male JIC to female JIC inline connection. Built from steel, this fitting belongs to the 6504 Series of JIC swivel extenders. It features a 7/16-20 thread form on both ends and is rated for a maximum operating pressure of 4500 psi at temperatures up to 375 degrees F. The swivel nut design allows the female end to rotate freely during assembly, reducing torque transfer to adjacent fittings and simplifying installation in tight or fixed-line routing situations. Licensed plumbers, hydraulic system technicians, and fluid power mechanics install this type of fitting in mobile and industrial hydraulic circuits.

This connector is suited for hydraulic systems where a straight, same-size JIC-to-JIC inline extension or swivel union is needed. Typical applications include mobile equipment, industrial machinery, and fluid power systems using 37-degree flare JIC fittings. The 4500 psi pressure rating makes it appropriate for medium- to high-pressure hydraulic circuits. With compact dimensions of approximately 1.5 inches in length and 0.6 inches in width, it fits into space-constrained plumbing runs without requiring additional adapters.

Installation Notes

This fitting is installed by licensed hydraulic technicians or fluid power mechanics following applicable fluid power system standards. Depressurize and bleed the hydraulic circuit completely before removing or installing any fitting. Inspect the 37-degree flare seats on mating components for nicks or damage before assembly. Do not exceed the rated operating pressure of 4500 psi in service.
