Crimp hydraulic hose fittings with ORS connection join hydraulic hoses to compatible ORS (O-Ring Seal) threaded equipment or hoses. Also called ORFS (O-Ring Face Seal) fittings, they have a crimped end that attaches to hydraulic hoses and an ORS threaded end that attaches to equipment. The ORS connection has an O-ring and straight threads that form a tight seal when joined to the opposite gender. A crimping device seals the fitting for a permanent connection. These fittings are commonly used in high-pressure applications to convey hydraulic fluids, lubricating oils, and fuel in custom hydraulic hose assemblies.
