These Mercedes-Benz tyre valve caps are crafted from wear-resistant aluminum with a black finish, providing a clean look for your wheels. Each cap features an internal gasket that ensures an airtight seal, which keeps dirt, dust, and moisture from entering the valve mechanism. Designed for a standard fit, they are compatible with most tyre valves and can be installed by simply screwing them on without any tools. The aluminum is treated for corrosion resistance to withstand various weather conditions, while the secure fit ensures they stay in place even when you are driving on rough roads.
