Vehicle Application and Placement

The seal is specifically designed for installation in the rear left part of the body, in the passenger door area. The dedicated vehicle placement: rear – left side simplifies the selection of the correct part for body repairs, replacement of corroded or leaking seals, and for bodywork and painting jobs.

The appropriately shaped rubber profile supports proper door closing, reduces rattles and play, and stabilizes the door leaf's position relative to the car body. This provides better protection for the vehicle's interior against the noise of airflow and water entering the sill area.

Technical and Functional Characteristics

The seal belongs to the group of body elements in the Doors and Door Sheet Metal class, directly interacting with the door panel, frame, and glass. The flexible rubber compound ensures adequate elasticity, allowing for multiple door openings and closings without loss of sealing under typical operating conditions.

• Stable guidance of the door edge in the rear left area.
• Reduction of water, dust, and dirt penetration into the vehicle interior.
• Improved cabin acoustic comfort by reducing external noise.
• Support for proper door closing and reduction of unwanted vibrations.

As an original Mercedes part, the seal is matched to the body geometry of the specific generation, minimizing the risk of leaks typical of universal replacements.

Product Condition and Service Application

The offered seal is a used part, making it an economical solution for operational repairs where maintaining the original construction at a reasonable service cost is a priority. This type of part is particularly suitable for:

• addressing leaks in the rear left door area,
• repairs after collisions and bodywork,
• body renovation to improve driving comfort.

Thanks to its factory fit, installation is predictable, without the need for modifications to the seal's shape or length. This is a practical option for workshops and users who service their cars themselves.

Selection by OEM Number and Purchase Support

When selecting a door seal for a Mercedes, it is crucial to compare the OEM number and vehicle placement. If in doubt, it is advisable to consult catalog data or seek service advice to avoid installing a part with a different profile or length. A practical guide describing the process of verifying parts by factory numbers can also be helpful – you can find it in the article Guide: How to Choose the Right Car Part by VIN and OEM Number.
