Abstract
An improved double wall hose and the method of forming the hose characterized by the hose comprising a helically wound member having a center part with extensions extending in opposite directions so that when adjacent turns of the member are joined together, a plurality of cavities are formed with one of the cavities containing a helical reinforcing member. Preferably, the reinforcement is of a material harder than the material forming the rest of the member and the turns of the member when joined together provide smooth continuous inner and outer wall surfaces for the hose.
