Purpose and function in the vehicle

The presented rear right window seal is a part of the Window seals and mouldings group, designed specifically for the Mercedes W251 body. It is mounted in the rear right part of the vehicle and works with the door window, creating a precise guide and a barrier against external factors.

Its tasks include, among others:

• preventing water and dust from entering the door interior and the cabin,
• reducing wind noise at higher speeds,
• stabilizing the window in the guide during lifting and lowering,
• protecting the window edge against excessive mechanical wear.

Construction and fitment for Mercedes W251

The seal profile has been developed for the specific dimensions and geometry of the rear door on the right side of the Mercedes W251, which ensures secure fitment with the door frame and proper adhesion to the glass. The appropriately shaped sealing strip works with factory mounting points, making the installation process predictable for an experienced mechanic or bodywork specialist.

The original Mercedes origin means maintaining the proper stiffness and flexibility of the material, which is essential for maintaining tightness over the long term of vehicle operation.

Service application and benefits of replacement

The component is particularly suitable for:

• post-accident repairs of the rear right side of the body,
• eliminating leaks around the rear door window,
• refurbishing the window guide system on the rear passenger side,
• reducing noise and vibrations coming from the door area.

Replacing a worn or deformed seal with an original component allows you to restore the factory level of tightness and acoustic comfort, and also reduces the risk of corrosion inside the door caused by moisture ingress.

Product characteristics and condition

The seal comes from dismantling, which means it is a used part that retains the functionality required for further operation. For vehicles serviced with original components, this is a reasonable cost-effective solution that allows you to maintain the consistency of the body elements used without having to resort to replacements with uncertain fitment.

Due to its factory origin from the Mercedes brand, the seal is structurally compatible with the window guide system and the kinematics of the lifting mechanism in the rear right part of the body, which facilitates installation and minimizes the risk of problems with door closing.
