The present invention relates to a hose having a layer consisting of a fluoropolymer onto which an unsaturated monomer has been irradiation-grafted and, a polyolefin outer layer. The hose is useful for transporting petrol in a service station. In one embodiment a fluoropolymer, preferably PDVF, layer is placed beside the irradiation-grafted fluoropolymer. The hose may consist of a irradiation-grafted fluoropolymer inner layer and a polyolefin outer layer, or multilayer hose with either a central irradiation-grafted fluoropolymer layer and polyolefin inner and outer layers, or a polyolefin central layer and irradiation-grafted fluoropolymer inner and outer layers. The irradiation-grafted fluoropolymer layer may be replaced with a layer of a blend of a fluoropolymer, preferably PVDF, and of an irradiation-grafted fluoropolymer. It may also be covered with a fluoropolymer.
