Power Steering/SMG Reservoir Cap Seal - E82, E36, E46, E9X, E34, E39, E60, E63, E38, E83, E53, Z3

This seal fits under the cap on the power steering or SMG fluid tank for E82, E36, E46, E9X, E34, E39, E60, E63, E38, E83, E53, Z3 models. It's quite common to have wet or dampness around the cap of SMG and PS systems but too much may be a sign of a failed o-ring seal (or could indicate system pressure is too high). Sometimes replacing the seal is the best first step to addressing the PS or SMG fluid leak on the tank. 

Made of oil-resistant EPDM synthetic rubber.
