ABSTRACT:
A flexible hose for fuels comprises a rubber inner layer, at least a reinforcement fabric layer and a covering rubber layer and, moreover, at least a fuel vapor low permeability material layer. With respect to prior flexible hoses for fuels, the inventive flexible hose has the advantage that it drastically lowers the gas leakages through the flexible hose wall, so as to meet the requirements of the enforcing rules in this field.
