Tank lid for closing off the tank connector of motor vehicles

摘要

A lid for closing off the tank connector of a motor vehicle is provided. An annular, elastic seal is disposed in a groove in an outer periphery of the lid. The seal serves for sealing the gap between the rim of the lid and the outer surface of the vehicle. At least part of the cross-sectional portion of the seal that faces the groove comprises an elastomeric material that is considerably harder than the actual sealing part.
