Detailed Description

URO part number 1267200378 is a body sealing component made for Mercedes-Benz SEC coupes with left-side fitment. The EPDM rubber construction is selected for durability in exterior automotive sealing applications, where exposure to moisture, airborne debris, heat, and sunlight can affect performance over time. Its OE-style profile is shaped to support a consistent seal between the door and body, which helps control cabin noise and maintain a tighter closure feel. This part cross-references URO-001092 for the same application.

Compatible With 1982-1983 Mercedes-Benz 380SEC, left; 1984-1985 Mercedes-Benz 500SEC, left; and 1986-1991 Mercedes-Benz 560SEC, left. If you are replacing a worn Mercedes-Benz SEC door seal, part number 1267200378 provides a direct-fit sealing solution for the listed vehicles.

What It Helps Address

• Water intrusion past a worn door opening seal
• Wind noise around the left door area
• Door squeaks caused by aged or hardened rubber
• Sticking or drag at the door-to-body contact surface
• Loss of sealing performance from cracked or compressed weatherstripping

Installation Notes

Verify left-side fitment before installation and compare the new seal to the removed part for profile and length. Clean the mounting surface thoroughly so the clip attachment seats properly and the seal can sit evenly along the door opening. For best results, inspect the door alignment and latch engagement before final closure.

Quality Assurance

URO backs this door seal with a 24 Month Unlimited Mileage Warranty. The EPDM material is heat- and UV-resistant, supporting long-term sealing performance on Mercedes-Benz 380SEC, 500SEC, and 560SEC models.
