Crimp hydraulic hose fittings with ORB connection join hydraulic hoses to compatible ORB (O-Ring Boss) threaded pipe or hoses. They have a crimped end that attaches to hydraulic hoses and an ORB threaded end that attaches to pipe. The male-threaded ORB connection has an O-ring and straight threads that create a tight seal when joined to female-threaded parts. A crimping device seals the fitting for a permanent connection. These fittings are commonly used in medium- and high-pressure applications to convey hydraulic fluids, lubricating oils, and fuel in custom hydraulic hose assemblies.
