Constructed from steel, it connects two tube ends of 3\/4 inch outside diameter with a rated maximum working pressure of 6000 psi. The ORFS interface provides a leak-free metal-to-metal seat backed by an O-ring, making it well-suited for demanding industrial, mobile hydraulic, and heavy equipment applications. This fitting is installed by hydraulic technicians, pipefitters, and maintenance mechanics working on fluid power systems.\u003c\/p\u003e\n\u003cp\u003eThis union fitting is used in hydraulic systems where a straight inline tube connection is required without welding or flaring beyond the compression sleeve. Typical installations include mobile equipment hydraulic lines, industrial machinery, and high-pressure fluid transfer circuits. The UNF thread standard ensures compatibility with standard inch-series hydraulic fittings and components common in North American equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eO-Ring Face Seal (ORFS) end connections for leak-free performance at high pressure\u003c\/li\u003e\n  \u003cli\u003eMaximum working pressure rated at 6000 psi\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch tube outside diameter\u003c\/li\u003e\n  \u003cli\u003eSteel construction for strength and durability in hydraulic service\u003c\/li\u003e\n  \u003cli\u003eUNF thread standard for compatibility with standard inch-series hydraulic components\u003c\/li\u003e\n  \u003cli\u003eUnion configuration allows straight inline connection of two tube ends\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service fitting for high-pressure hydraulic tube assemblies using 3\/4 inch OD tubing with O-Ring Face Seal connections and UNF thread standard.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified hydraulic technician or pipefitter. Depressurize and isolate the hydraulic circuit completely before disassembly or fitting installation. Inspect the O-ring sealing surface for damage or contamination prior to assembly, and use a new O-ring if reusing the fitting.
