Purpose and function in the bodywork

The outer window seal on the rear right door is responsible for stable glass guidance and limiting the ingress of water and contaminants into the door interior. A properly selected profile minimizes wind noise at higher speeds and supports the correct operation of the window lifting mechanism. In the case of a used vehicle, replacing a worn seal with a component from the same design group allows for restoring the proper fit of the glass to the door frame.

Benefits of using an original seal

Using a component originating from the same production line as factory body parts ensures:

• proper fit to the shape of the door and window frame,
• correct cooperation with guides and the lifting mechanism,
• reduction of the risk of rattling, play, and leaks in the window area,
• maintenance of a consistent visual line with other trim elements.

For the user, this means stable window operation and more comfortable acoustic conditions inside the vehicle, without the need for structural modifications to the door.

Application in repairs and upgrades

The rear right outer window seal is suitable both for typical replacement of a worn element and for post-accident repairs when it is necessary to restore the original geometry of the window area. Replacing this component is particularly recommended when the following occur:

• water streaks in the area of the upper door edge,
• increased noise in the cabin when the window is slightly open or closed,
• signs of abrasion on the glass edge resulting from improper guidance.

By maintaining the factory profile, the seal allows for service in a manner similar to solutions used in authorized service centers, without the need for modifying the door structure.

Integration with other body components

The element belongs to the Window seals and moldings group, working in conjunction with other door seals and window guides. Proper installation affects the tightness of the entire window perimeter, which is important both for the anti-corrosion protection of the door interior and for the comfort of using the vehicle in daily operation. In the case of extensive body and paint work in the rear part of the body, replacing the seal is a natural step in restoring the original performance parameters of the door.

If you are planning a comprehensive repair or upgrade of the window area in your Seat and need other elements from the same group, such as window moldings, additional seals, or glass edge trims, check the available parts in the Seat window seals and moldings category.
