Vehicle Application and Placement

The presented seal is designed for installation in the rear right part of the body, in the area of the body window. It is responsible for:

• sealing the contact between the window and the body in the rear part of the vehicle,
• limiting the ingress of water and moisture into the interior,
• reducing wind noise during driving,
• maintaining the stable position of the window relative to the body frame.

Thanks to its proper profile and fit for the specific W251 model series, the seal works with the factory body geometry, which facilitates installation and helps maintain a consistent look of the vehicle's side line.

Technical and Functional Characteristics

The rear right body window seal has been manufactured as a dedicated part for Mercedes vehicles. The construction is designed to operate under typical passenger car operating conditions – variable temperatures, exposure to UV radiation, and contact with water and road contaminants.

Key functional features:

• profile matched to the window frame in the W251 body,
• designed to work with factory mounting points,
• appropriate flexibility for easy installation and removal,
• maintaining a seal in the rear right body window area.

As a part from the Window Seals and Trim category, the product supports maintaining proper acoustic comfort and reduces the risk of dampness in the upholstery and structural elements in the rear cabin.

Product Condition and Service Application

The offered seal is a used part, making it a practical choice for post-accident repairs, replacement of worn or leaking seals, and for the reconstruction of the side body area. This type of component is particularly useful when:

• the existing seal has suffered mechanical damage (cracks, tears),
• there are leaks in the rear right window area,
• after replacing the window, it is necessary to fit a seal that matches the factory standard.

Using an original part from disassembly allows for maintaining the structural integrity of the body and reducing the risk of fitting problems, which are typical for universal aftermarket alternatives.

Benefits of Using an Original Mercedes Seal

Choosing a seal dedicated to the W251 series offers a range of practical service and user benefits:

• Factory Fit – the seal's geometry matches the original window frame, which facilitates installation and minimizes the need for additional adjustments.
• Stable Sealing of the Rear Body Area – reduction of air drafts and water ingress in the rear right window area.
• Support for Driving Comfort – improved acoustic insulation in the rear cabin, especially at higher speeds.
• Cost-Effective Solution – a used original part is an alternative to new parts, while maintaining compatibility with the vehicle's construction.
