Purpose and vehicle placement

The presented seal is dedicated for installation in the rear right part of the body, in the area of the door and side window. The component's design has been prepared for specific mountings and body geometry, which allows for:

• precise guidance of the window edge in the guide rail,
• stable sealing of the contact between the window and the door frame,
• reduction of air drafts at higher speeds,
• maintaining the proper operation of the window lifting mechanism.

Thanks to its fit for the rear right side of the vehicle, the seal works with the factory door construction without the need for sheet metal modifications or additional profile adjustments.

Technical and functional characteristics

The seal is made of flexible rubber with parameters selected for operation in variable weather conditions. The material used ensures:

• adequate elasticity, facilitating installation in the door frame,
• shape retention over a long period of use,
• resistance to typical operational loads, such as frequent opening and closing of the door.

The seal profile has been designed to create a continuous barrier between the window and the body, which translates into better cabin acoustic insulation and limits the ingress of water and contaminants into the door interior.

Benefits of using an original Mercedes seal

Using an original element from the Window seals and trims group in a Mercedes allows for maintaining the structural consistency of the body. Key advantages include:

• factory fit to the shape of the door and window on the rear right side,
• reduced risk of leaks compared to universal profile replacements,
• maintaining the aesthetic contact line between the window and the door frame,
• support for the proper operation of the window lifting mechanism, without additional resistance.

This solution is particularly useful for post-collision repairs, replacing corroded body parts, or restoring vehicle comfort after years of use.

Condition of the item and practical application

The offered seal is a used part, which allows for economical repair while maintaining the manufacturer's original specifications. In practice, it will work well both for spot replacement of a single seal and for broader bodywork and paint repairs in the rear part of the body. It is recommended to perform the installation while maintaining the correct positioning of the profile in the guides and checking the window operation after installation to fully utilize the factory fit of the component.
