Abstract:
1. A method of making a hose, comprising the steps of: providing an innermost tubular member that defines an opening therein and having an inner surface and an outer surface, where the inner surface is smooth throughout, and where the innermost tubular member comprises a fluoropolymer material; forming an inner layer of silicone adjacent to and bonded to the outer surface of the innermost tubular member, the inner layer having an outer surface; providing a wire braided reinforcement layer adjacent to an outer surface of the inner silicone layer, wherein gaps between wires of the reinforcement layer are larger than a diameter of said wires; forming an outer silicone jacket adjacent to the reinforcement layer by applying a liquid silicone mixture onto an outer surface of the reinforcement layer such that said liquid silicone mixture penetrates through said gaps between said wires of the reinforcement layer onto the outer surface of the inner silicone layer and curing the liquid silicone mixture to a hardened state to bond the outer silicone jacket to the outer surface of the inner silicone layer.
