A pre-rinse hose for use in the food service industry is provided. A core section is formed from an inner tube extruded from a rubber compound, a layer of textile braid applied to the inner tube and an outer tube extruded from a rubber compound over the textile braid. A steel braid is applied around the outer tube and a cover of polyvinyl plastic material is extruded over the steel braid. A hollow stem is held in each end of the hose by a ferrule which is crimped and compressed over the hose ends. A wrench-faced nut is disposed on each hollow stem to connect one end of the hose to a faucet and the other end to a pre-rinse spray head. A spring is applied around the end of the hose connected to the faucet to reinforce the hose against breakage.
