• reduces wind noise at higher speeds,
• helps maintain a stable temperature inside the vehicle,
• minimizes vibrations and creaks resulting from door operation.

The product comes from the Mercedes brand's offering, which helps maintain the factory standard of fit and compatibility with the body structure. This ensures the seal integrates seamlessly with the door line and bodywork, and after proper installation, it does not require any additional modifications.

The offered seal is a used part, which in practice means the possibility of an economical repair while maintaining the original geometry of the component. Before installation, it is recommended to perform a standard inspection of the seal's working surface and thoroughly clean the door edges and adjacent body elements to ensure even adhesion.

When replacing, pay attention to:

• correct positioning of the profile around the entire perimeter of the door,
• thorough pressing in the corner areas,
• checking the door closure after installation, including even pressure along the entire length.
