Reusable hydraulic hose fittings are a type of hydraulic fitting that allows the user to reuse the fitting instead of disposing of it after a single use. These fittings consist of two parts: a reusable fitting and a hose tail. The reusable fitting has a threaded collar that can be screwed onto the hose, and a swivel nut that tightens the fitting onto the mating fitting. The hose tail is attached to the reusable fitting and is designed to fit into the hydraulic system.
