    摘要： A hose of low fuel permeability has a fuel permeability in a bent state with R50 not more than three times a fuel permeability in a straight state, R50 being a bent state where the hose has its longitudinal axis bent to form an arc having a diameter of 100 mm. Its low fuel permeability is achieved if the resin forming its inner wall layer has a melt viscosity falling within a certain range, which can be obtained by, for example, increasing the degree of polymerization of the resin, or grafting a specific side chain to the main chain in each molecule of the resin, or if the resin has a volume swelling degree falling within a certain range, which can be obtained by copolymerizing a monomer having fuel resistance, or blending a polymer having fuel resistance. The hose maintains its low fuel permeability even if it may be subjected to a large load of bending stress as when it is used to form a fluid conveying line.

    摘要： A tank joint part has a welding member welded to the outer surface of a fuel tank and a main body formed of a material of low fuel permeability and welded or otherwise joined to the welding member. The welding member is formed of modified polyethylene, which is easily weldable or otherwise joinable to the outer surface of the fuel tank and the main body, and in which very fine particles of a layered mineral are easily dispersible. The mineral is dispersed in layers oriented substantially at right angles to the direction of any possible permeation from the tank joint part. The tank joint part ensures a low fuel permeability and a high bonding strength.

    摘要： A fuel hose comprising a rubber layer and a fluororesin layer formed on the inner surface of the rubber layer, in which the adhesion to the fluororesin layer is improved by blending from 2 to 15 phr of a phenol-type resin with the rubber forming the rubber layer. Phenol resins of a specific polymeric structure are particularly preferred as the phenol-type resins. A fluororesin layer formed by melting a fluororesin and allowing it to adhere to the inner surface of the rubber layer by powder coating is particularly preferred. The provision of the fluororesin layer on the inner surface of the rubber layer enables simple and effective adhesion of the thinned fluororesin layer to the rubber layer.
