Crimp hydraulic hose fittings with NPTF connection join hydraulic hoses to compatible NPTF (National Pipe Tapered Fuel) threaded equipment or hoses. They are typically used in hydraulic hose assemblies to convey fuel in automotive applications. They have a crimped end that attaches to hydraulic hoses and an NPTF threaded end that attaches to equipment. The NPTF connection (or dryseal thread) forms a tight seal when mated with the opposite gender. A crimping device seals the fitting for a permanent connection. These fittings are made of steel for strength, durability, and wear-resistance in high-pressure applications, or carbon steel that is hard and resilient, but more susceptible to corrosion unless alloyed with other metals for resistance.
