• Fits front left door applications on select Mercedes-Benz sedans

Detailed Fitment and Function

Part number 1267200178 is engineered for the front left door opening on compatible Mercedes-Benz W126-era sedans. It is a practical replacement when the original door seal has hardened, compressed, or begun to leak. This part cross-references URO-001090 for the same application.

Common Issues This Seal Can Address

• Water entering the cabin through the front left door opening
• Wind noise at highway speeds
• Door squeaks caused by worn sealing surfaces
• Airborne dust and debris intrusion around the door frame
• Sticking or drag when opening and closing the door

Installation Notes

Inspect the door frame and pinch-weld area before installation and remove any old adhesive, dirt, or corrosion. Confirm the seal is seated evenly around the opening so the door closes without excessive force. For best results, verify fitment by year, model, and front left position before ordering part number 1267200178.

Quality Assurance

URO backs this door seal with a 24 Month Unlimited Mileage Warranty. The EPDM rubber construction is designed to withstand heat and UV exposure while maintaining a consistent sealing profile over time.
