The EPDM rubber material is selected for durability in heat and sunlight, making it a practical replacement for worn or compressed original sealing material.

Installation Notes and Tips

Inspect the door frame and sealing channel before installation so the new seal seats evenly. Clean away old adhesive, dirt, and hardened rubber residue to support proper adhesion and fit. Confirm alignment along the full perimeter of the front left opening on the Mercedes-Benz 300SD before closing the door.
