Purpose and Body Fitment

The rear left door seal strip is designed as a component mounted on the edge of the rear driver's side door window. Its placement on the vehicle is clearly defined, making it easy to select the correct part during bodywork repairs or replacement after a collision or due to wear and tear.

The black color of the strip allows for an aesthetically pleasing match with most body styling configurations, including standard versions and more elaborate equipment packages. This ensures the part does not disrupt the vehicle's side profile and maintains its factory finish.

Wiper Function and Window Protection

The seal strip is responsible for maintaining proper contact with the window surface, which limits the ingress of water, dirt, and small particles between the window and the door. A correctly fitted strip:

• stabilizes the window's movement within its guide during opening and closing,
• reduces the risk of scratches on the glass,
• contributes to maintaining a watertight seal around the door frame,
• minimizes noise caused by window vibrations while driving.

Thanks to its construction, which aligns with the manufacturer's solutions, the strip works in conjunction with the window lifting mechanism and other door seals, contributing to acoustic comfort inside the cabin.

Product Characteristics and Condition

The offered seal strip belongs to the OEM class of body parts intended for Mercedes vehicles. The product is used, allowing for an economical replacement of a worn or damaged part while maintaining original geometry and compatibility with the rear left door.

Choosing an original used seal strip is advantageous wherever maintaining factory fitment with the window and door panel is crucial, while also optimizing body repair costs.
