Built for a Precise OE-Style Seal

Part number 1238260158 is made to match the original sealing shape used on Mercedes-Benz 300D rear lamp assemblies. The EPDM rubber material is selected for durability in exterior automotive use, where exposure to heat, sunlight, and weather can cause lesser seals to harden or crack. By maintaining a consistent seal around the tail light lens, this part helps protect the reflector and lens area from contamination that can lead to clouding or darkening.

This part cross-references URO-013493 for the same application.

Common Problems This Seal Can Help Address

• Water intrusion behind the tail light lens
• Dust buildup around the rear lamp housing
• Clouding or darkening of the lens and reflector area
• Wind noise caused by a worn or flattened seal
• Cracked, hardened, or missing original tail light sealing material

Installation Notes and Tips

Clean the mounting surface before installation so the new seal can seat evenly. Inspect the tail light housing and lens for damage or distortion that could affect sealing performance. Confirm left or right side placement before installation on your Mercedes-Benz 300D, and verify the seal profile matches the original part number 1238260158.
