ABSTRACT:
A multi-layered hose according to the present invention comprises a rubber outer layer and a resin or metal inner layer which is integrally formed at the inner periphery surface of the rubber outer layer. The thickness of the resin inner layer formed at the inner periphery surface of the edge portion is thinner than that of the resin inner layer formed at the inner periphery surface of a main portion of the hose. Therefore, when a mating pipe is inserted into the hose edge portion, the mating pipe is satisfactorily adhered to the inner surface of the hose edge portion, thereby obtaining excellent sealing.
