Purpose and vehicle placement

The presented seal is dedicated to installation in the rear right part of the body, in the passenger door area. The placement on the vehicle, defined as rear – right side, allows for clear identification of the correct mounting position and reduces the risk of error when selecting the part. This allows the user to focus on precisely seating the seal in the window guide and the door structure.

Technical and functional characteristics

The seal works in direct contact with the door window, stabilizing its movement in the vertical guides and creating a barrier between the interior and the external environment. The properly profiled cross-section supports:

• reduction of air drafts at higher speeds,
• reduction of window vibrations and rattling in extreme positions,
• sealing of the edges in the contact zone between the window and the door frame.

Such properties translate into more stable operation of the lifting mechanism and consistent acoustic comfort in the rear part of the cabin.

Benefits of using an original seal

Using a component from the Door Upholstery group dedicated to a specific Mercedes model allows for maintaining compliance with the factory door geometry. Proper adjustment of length, shape, and mounting points facilitates installation and minimizes the need for additional modifications. In practice, this means:

• more predictable fitment with the door frame and window,
• lower risk of leaks after replacement,
• maintaining the aesthetics of the window edge at a level close to factory standards.

The product in used condition can be an attractive alternative to new components, especially for maintenance repairs where maintaining functionality at reasonable service costs is key.

Practical installation tips

When replacing the window seal in the rear right door, it is worth paying attention to the cleanliness of the contact surface and the condition of the window guides. It is recommended to:

• thoroughly clean the mounting slots of old seal residues and dirt,
• check the free movement of the window after initially seating the new element,
• check the operation of the lifting mechanism in the full range before finally closing the door upholstery.

Such an approach helps to fully utilize the sealing potential and ensures stable window operation in daily use.
