Threaded at 9\/16-18 on the JIC end and 1-1\/16-12 on the O-Ring Boss end, this adapter is rated for 3600 psi working pressure, with a 4500 psi non-adjustable pressure rating. It is used in hydraulic plumbing circuits where a JIC-to-ORB transition is required. Hydraulic technicians and equipment mechanics install this fitting when routing steel or hose assemblies between pumps, cylinders, valves, and manifolds in mobile or industrial hydraulic systems.\u003c\/p\u003e\n\u003cp\u003eThis adapter suits hydraulic applications in construction equipment, agricultural machinery, and industrial fluid power systems. It is part of the 6400 Series, covering Male JIC to Male O-Ring Boss configurations in steel. The compact dimensions allow installation in tight plumbing runs where space is limited. It is appropriate for use in both new plumbing assemblies and field repair applications where a JIC-to-ORB conversion is needed at the port connection.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-inch Male JIC to 3\/4-inch Male O-Ring Boss configuration for common hydraulic port conversions\u003c\/li\u003e\n  \u003cli\u003e3600 psi working pressure rating for standard hydraulic circuit use\u003c\/li\u003e\n  \u003cli\u003e4500 psi non-adjustable pressure rating for high-demand applications\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in hydraulic plumbing environments\u003c\/li\u003e\n  \u003cli\u003e9\/16-18 x 1-1\/16-12 thread specification for precise fitting identification\u003c\/li\u003e\n  \u003cli\u003eCompact size at 1.55 inches length supports installation in confined spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-duty replacement or new-installation fitting for hydraulic systems requiring a Male JIC to Male O-Ring Boss adapter in the 6400 Series configuration.
