Perfect Sealing
Gates fuel caps offer a durable construction of a wear-resistant thermoplastic compound to ensure tight closing and to avoid spills and leaks. Gates' standard fuel cap range includes locking and non-locking caps. The locking fuel caps fix securely and make tampering with your fuel tank impossible. All fuel caps are easy to install.

Optimum Fuel Pressure
On the inside, the caps can have two different breathing systems: vented or non-vented. A non-vented fuel cap is recommended when your fuel tank is ventilated through the filler neck, whereas the vented fuel cap is equipped with a special breathing valve so that it can be used on non-ventilated fuel tanks.

Cleaner Environment
In order to reduce air pollution as much as possible Gates supplies a special ecological cap. It is fitted with a venting valve system which prevents evaporation of harmful car fuel gases and complies with the EEC directive No. 70/221. In case of an accident the safety valve prevents fuel leaking from the tank.

Caps with controlled pressure release technology allow pressure built up in the fuel tank on hot days to be released gradually when the cap is opened. This prevents fuel from erupting and spraying out on the motorist. Below are the three types of controlled pressure release cap styles (not all styles are available for all applications):

Push Vent

The color of the cap can be used to identify the vehicle's fuel compatibility. The physical cap is the same, regardless of color.
