    Fuel Caps

    with Vent

    Often used with trailers, compressors, and other equipment tanks, these caps meet Department of Transportation requirements. Caps have fusible plugs that will melt when the outside environment reaches their opening temperature.
    Fuel Caps with Vent—Cap with vent will automatically open when the internal pressure reaches between 6.5 psi to 8.5 psi to relieve pressure.
