A high pressure hose has an inner tube comprised of a thermoplastic material that defines a fluid carrying passageway. A reinforcing layer is formed by a plurality of steel wires helically wound in opposite directions over the inner tube along its longitudinal axis. An outer layer of thermoplastic material extends over the reinforcing layer and fills the voids in and under the wires of the reinforcing layer so that the thermoplastic outer layer permanently fills the voids in the wires of the reinforcing layer and is fused to the outer surface of the inner tube.
