Gates is synonymous with high-quality products and services that solve problems and add value. Gates is supplier to many car manufacturers, which enables Gates to provide OE-equivalent products to the automotive aftermarket. 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.
