It is good to the invention provides anti-fuel breathability, simultaneously the fuel hose of interlaminar adhesion.Fuel hose with the layer structure that constitutes by the resin layer of tubulose with the rubber layer of this resin layer adjacency, it is necessary composition that above-mentioned rubber layer uses following (A)～(E), contain as the composition formation of following (F) of composition arbitrarily in the ratio less than 0.1 weight portion with respect to (A) 100 weight portions, simultaneously above-mentioned resin layer uses hexafluoropropylene (HFP)/tetrafluoroethylene (TFE)-vinylidene-perfluoroalkyl vinyl ether quadripolymer to form for the material of main component.(A) diene series rubber; (B) sulphur is vulcanzing agent; (C) be selected from 1,8-diaza-bicyclo [5.4.0] endecatylene-7 salt, 1,5-diaza-bicyclo [4.3.0]-nonene-5 salt, 1,8-diaza-bicyclo [5.4.0] endecatylene-7 and 1,5-diaza-bicyclo [4.3.0]-nonene-5 are formed at least a among the group; (D) carbamic acid slaine and thiazole are at least one side of slaine; (E) magnesium oxide; (F) zine oxide. |
