• Fits 1978-1980 Mercedes-Benz 300SD
• Long-life EPDM rubber resists water, airborne dust, heat, and UV exposure
• OE-style seal profile supports a precise rear glass fit
• Helps reduce wind noise around the back glass opening
• URO 1166700039 for direct replacement use

Sealing Performance and Fitment

Built for the Mercedes-Benz 300SD, this back glass seal is shaped to match the original sealing profile and support a secure rear window installation. The EPDM rubber construction is selected for durability in exterior body sealing applications, where exposure to sunlight, temperature changes, and moisture can affect older seals. If you are replacing a worn rear window gasket on a 1978, 1979, or 1980 Mercedes-Benz 300SD, URO 1166700039 provides a direct-fit sealing solution.

This part cross-references URO-000804 and V30-1552 for the same application.

Common Problems This Seal Can Address

• Water leaking past the rear glass seal
• Dust entering around the back window opening
• Wind noise from a hardened or shrunken gasket
• Cracking, drying, or UV damage in the original seal
• Poor rear glass sealing after body repair or restoration

Installation Notes

Inspect the glass channel and body flange before installation. Remove old adhesive, corrosion, and debris so the new seal can seat evenly. Verify the rear glass and surrounding trim are aligned before final assembly to help maintain a uniform seal.

Quality Assurance

URO backs this back glass seal with a 24 Month Unlimited Mileage Warranty. The EPDM rubber construction is designed for exterior sealing performance and long-term resistance to heat and UV exposure.
