Fuel Caps for Light and Heavy Duty Applications
Fuel caps prevent fuel vapor leakage from the filler neck, which is a major source of hydrocarbon emissions, and play a major safety role in preventing the flow of fuel from the tank filler neck when a car is in an accident, including rollovers. Studies demonstrate that a defective or missing fuel cap can allow up to 114 liters (30 gallons) of fuel to evaporate into the atmosphere every year. For all these reasons, using a high-quality fuel cap is vital to safety, fuel economy and the environment. fuel caps are designed and manufactured to prevent such fuel loss.
offers more than 60 different types of fuel caps and more than 50 types of locking fuel caps, all engineered to minimize fuel vapor loss while maximizing safety and ease of use.
Fuel Caps
standard fuel caps pass all state and federal emissions requirements. The caps are specifically designed with pressure and vacuum relief valves to prevent evaporation of fuel.
