  • Kink-resistant fuel hose liner
    Patent number: 5573039
    Abstract: Hoses are provided which are resistant to chemical and thermal attack and which include a polymeric liner having an integral resilient member axially located along its wall. The resilient member includes a tensile strength which is significantly greater than the polymeric material of the liner, so as to minimize the incidence of plastic deformation and kinking during manufacture, installation, and use.
