ABSTRACT:
A flexible hose has a thermoplastic core tube, a reinforcing layer surrounding the core tube, an elastomeric sheath surrounding and bonded to the reinforcing layer, and a plastic fiber protection layer surrounding and adhering to the sheath. The hose can be made by applying a layer of viscous cement to the reinforcing layer applied around the core tube, wrapping the viscous cement layer, with an overlapping seam, with a calendered layer stock of elastomeric material, and applying an abrasion protection layer around the elastomeric material. The hose is self-curing at ambient temperature and can be made on conventional hose manufacturing equipment.
