Claim:
1. A high pressure hose comprising: an inner tube comprised of strong, highly flexible thermoplastic material that defines a fluid carrying passageway, the inner tube having an outer surface and a longitudinal axis; a reinforcing layer comprised of a plurality of substantially parallel high tensile strength steel wires helically wound in opposite directions over the outer surface of the inner tube along its longitudinal axis; the wires of the reinforcing layer intersecting and forming a braided structure surrounding the outer surface of the inner tube, the reinforcing layer of wires inherently leaving voids between and beneath the braided structure of wires and the inner tube; and an outer layer of thermoplastic material extending over the reinforcing layer of wires and extending inwardly to the outer surface of the inner tube below the wires of the reinforcing layer so as to fill the voids in and beneath the braided structure without altering the outer surface of the inner tube, whereby the thermoplastic outer layer permanently fills the voids in and beneath the wires of the reinforcing layer so that the entire surface of the outer layer is fused to the outer surface of the inner tube.
