Replace your factory plastic valve caps with durable aluminum alloy tire valve stem caps designed specifically for Smart models including Fortwo, Forfour, Forjeremy, Forvision, Brabus Roadster, and the 451 and 453 generations. These caps provide a secure seal to help maintain stable tire pressure and prevent flat tires caused by air leaks.

Each cap features a high-quality sealing ring inside to block dirt, moisture, and road debris from reaching the valve core.

Usage Scenario
