PURPOSE:To obtain a rubber hose equipped with all of required characteristics for fuel by constituting an inner pipe rubber layer of an inside layer composed of a compound based on a blend polymer (a) of acrylic rubber and a fluorocarbon resin and an outside layer composed of a compound based on a blend polymer (b). CONSTITUTION:A rubber hose is equipped with an outer pipe rubber layer 3 and the inner pipe rubber layers 1a, 1b positioned inside said layer 3, and the inner pipe rubber layer is constituted of the inside layer 1a composed of a compound based on a blend polymer (a) of acrylic rubber and a fluorocarbon resin and an outside layer 1b composed of a compound based on a blend polymer (b) other than the above-mentioned blend polymer (a) and the blend polymer (b) contains at least epichlorohydrin rubber. When a compound based on the blend polymer containing the epichlorohydrin rubber is used as the compound for forming the outside layer of the inner pipe rubber layer, the vulcanization adhesiveness of the inside and outside layers is excellent and the deterioration of the low temp. characteristic of the whole of the inside layer can be prevented.
