Patent ID: 8865280

Claim:
A fuel hose, comprising: a tubular inner rubber layer, a resin layer formed on an outer circumferential surface of the inner rubber layer; and an outer rubber layer formed on an outer circumferential surface of the resin layer, wherein the inner rubber layer comprises a rubber material comprising the following Components (A), (B), and (C), wherein the outer rubber layer comprises a rubber material comprising the following Components (A′), (B), and (C′), wherein the resin layer comprises a resin material comprising the following Component (X) as a main component: (A) acrylonitrile-butadiene rubber, (A′) blend rubber comprising acrylonitrile-butadiene acrylic rubber and ethylene acrylic rubber, (B) a sulfur vulcanizing agent, (C) an amine catalyst to form bonding points, (C′) an amine catalyst to form bonding points, which comprises 1,5-diazabicyclo(4.3.0)non-5-ene salt and 1,8-diazabicyclo(5.4.0)undec-7-ene salt, and (X) tetrafluoroethylene-perfluoro(alkylvinylether)-chlorotrifluoroethylene copolymer and wherein the ratio of 1,5-diazabicyclo(4.3.0)non-5-ene salt and 1,8-diazabicyclo(5.4.0)undec-7-ene salt is from 1/10 to 1/0.1, and wherein in the Component (A′) the blending ratio of acrylonitrile-butadiene rubber to acrylic rubber is in the weight ratio of 90/10 to 80/20.
