Sealing Performance and Fitment

Part number 1237201578 is made for Mercedes-Benz 300D and Mercedes-Benz 300TD applications where a front left door seal is needed. The EPDM rubber construction is shaped to match the vehicle opening closely, helping maintain a tight seal against the body and reducing the noise and moisture issues that often come from worn weatherstripping. This part cross-references URO-000942 for the same application.

Common Issues This Part Can Address

• Water entering the cabin through a worn front left door opening
• Wind noise around the driver-side door
• Door squeaks caused by hardened or flattened sealing material
• Dust and airborne debris passing through a degraded seal
• Sticking or drag between the door and body at the seal surface

Installation Notes and Tips

Before installation, inspect the door frame and body flange for old adhesive, corrosion, or deformation that could affect sealing. Clean the mounting surface thoroughly so the new seal can sit evenly along the opening. Verify the chassis range on 1977-1981 Mercedes-Benz 300D models before ordering, since this application is limited to vehicles from chassis 067050 onward.

URO backs this door seal with a 24 Month Unlimited Mileage Warranty. Part number 1237201578 is engineered for guaranteed fitment and uses durable EPDM rubber to support consistent sealing performance over time.
