Fuel Hose

摘要

A fuel hose (10) for a fuel pipeline in an motor vehicle has a multilayer structure including a resin barrier layer (12) having low permeability to fuel, an outer rubber layer (14) laminated on an outer side of the barrier layer (12) and an inner rubber layer (16) laminated on an inner side of the barrier layer (12) and defining an inner surface layer of the fuel hose (10). The multilayer structure is formed throughout an entire length of the fuel hose (10). A rubber hardness of the inner rubber layer (16) is higher than a rubber hardness of the outer rubber layer (14).
