ABSTRACT:
A method of manufacturing a hose includes the step of extruding a tube assembly comprising (i) a first inner non-foamed layer, (ii) a first outer non-foamed layer positioned around the first inner non-foamed layer, and (iii) a first foamed layer interposed between the first inner non-foamed layer and the first outer non-foamed layer. The method further includes the step of positioning a textile reinforcement on the tube assembly. Additionally, the method includes the step of extruding a cover assembly over the textile reinforcement, the cover assembly comprising (i) a second inner non-foamed layer, (ii) a second outer non-foamed layer positioned around the second inner non-foamed layer, and (iii) a second foamed layer interposed between the second inner non-foamed layer and the second outer non-foamed layer.
