    Prevent Cap Assembly

    • For Above-Ground Storage Tanks
    • Gasoline and Diesel Fuel
    • Used as a Fill Cap
    • Convenient to Lock (K408A)

    STOPS or REDUCES:

    • Evaporation Loss
    • Water Condensation
    • Gasoline Weathering
    • Loss of starting quality
    • Loss of delivered Octane Rating
    • Gum Formation
    • Crankcase Oil Dilution

    Gasoline stored in above ground tanks equipped with open vent caps can cost you many dollars in evaporated gasoline. You can reduce such loss by installing a PreVent cap. PreVent maintains about 2.5 PSI in the storage tank, preventing vapors from leaving the tank. Diesel fuel presents another problem - water condensation inside the tank. The PreVent cap will reduce such condensation. Relieves vacuum for pump out rates to 30 GPM.
