The inner and outer rubber hose of the inlet and outlet gas or multi-channel cooling water of automobile intercoolers includes the body of the rubber hose. The inner surface of the body of the rubber hose is vulcanized and bonded with an inner rubber layer. The inner rubber layer is made of the modified material after the blending of fluoropubmer and silicone rubber. Through the utility model on the inner surface of the silicone tube set on fluorine polymer material, make it has outstanding resistance to ozone, corrosion resistant, flame retardant and excellent oil resistance, can contain alcohol, salt, including amine and alkyl phenol compound medium such as work, due to the high temperature of fluoropolymer oil permeability is only 1/100 of the silica gel, so can effectively improve the hose closure, can effectively slow down the aging, rubber hoses, improve its service life.
