The base gasket performs two essential functions: it seals the interface between the mirror base and the door panel, preventing water and wind noise from entering the cabin; and it protects the painted door surface from abrasion and stress caused by mirror mounting hardware and vibration.

On older vehicles, the original gaskets often become brittle, compressed, split, or missing entirely due to age and environmental exposure. A compromised gasket can allow water ingress, cause paint deterioration at the mirror base, and contribute to wind noise at road speeds. This OE Match gasket restores proper sealing and finish with a direct-fit replacement that installs easily with the original mirror and hardware.
