    OE Quality for the Aftermarket

    Our long-standing partnerships working with automotive OEMs on production vehicles enable us to produce aftermarket parts of superior quality, durability, and performance. Gates® Flex Fuel Caps offer a durable construction of wear-resistant thermoplastic compound to ensure tight closing and prevent spills and leaks. Our OEM-caliber fuel caps are rich in features that keep the fuel system operating properly and safely. The Yellow color and E85 designation reminds motorists of the option to use gasoline or E85 ethanol in their vehicles.

    Optimum fuel pressure

    Fuel 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.
