Purpose and Function of the Window Seal

This seal is designed for installation in the front right door area, where it works with the window lifting mechanism and door upholstery. Its functions include:

• sealing the contact between the window and the door frame,
• reducing air drafts at higher speeds,
• minimizing wind noise and vibrations,
• protecting the door interior from water and small debris.

By maintaining its original geometry, the seal profile works seamlessly with the factory door construction, promoting stable window operation and improving cabin acoustics.

Benefits of Using an Original Mercedes Seal

Using a genuine Mercedes part ensures technical consistency with other door components. The original profile and rubber compound hardness promote proper window pressure and even force distribution during window operation.

Key advantages include:

• compatibility with the W164 front right door construction,
• maintaining the original window-to-frame sealing line,
• reducing the risk of leaks common with ill-fitting aftermarket parts,
• preserving the aesthetic seal between the window and door upholstery.

For the user, this translates to more stable window operation, reduced cabin noise, and better interior protection from external elements.

Installation Characteristics and Application

The seal is intended for installation in the front right door area, where it interacts with the frame, window, and trim elements. Its dedicated placement on the vehicle simplifies identification of the correct side and mounting position, which is crucial for bodywork servicing.

This part is particularly suitable for situations where:

• there are air drafts with the window closed,
• water streaks appear around the upper edge of the door,
• an increase in cabin noise is noticeable on the passenger side,
• the existing seal is deformed or mechanically damaged.

Choosing a seal dedicated to a specific body model reduces installation time and avoids issues with profile fitting to the door edge.

Item Condition and Usage Aspects

This seal is a used part, allowing for factory-like performance at a more favorable cost compared to new parts. Its original Mercedes origin helps maintain proper flexibility and geometry in the working areas where it contacts the window.

This solution is particularly beneficial for maintenance repairs where a combination of correct fit, predictable long-term performance, and cost-effective bodywork servicing is essential.
