Prevent Cap

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


• 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.
