Seal Purpose and Function

The presented seal is specifically designed for installation in the rear left part of the body, in the door and side window area. It is responsible for maintaining proper sealing between the window and the door frame, which translates to preventing water and dust ingress and reducing wind noise during driving.

Thanks to its factory profile and appropriately selected material flexibility, the component ensures stable vertical window guidance, supporting the correct operation of the lifting and lowering mechanism. A properly selected seal also helps reduce window vibrations, contributing to acoustic comfort inside the vehicle.

Original Volkswagen Fitment

The seal comes from the Volkswagen range, meaning it adheres to factory dimensional and structural standards. The original profiling of the edges and contact points with the door frame and window facilitates installation and minimizes the risk of leaks after replacement.

Using original components in such critical areas as the window-body contact zone helps maintain the structural integrity of the door and preserves the driving comfort parameters intended by the manufacturer, including noise levels and protection against external factors.

Benefits of Replacing a Window Seal

Replacing a worn or damaged rear left window seal with a functional part offers a range of practical benefits:

• Reduced water ingress into the door and cabin,
• Decreased wind noise and creaks from the window area,
• More stable window guidance in the track,
• Support for the correct operation of the window lifting mechanism,
• Maintaining a neat seal between the window and the door frame.

For users who want to consistently use original solutions, this is a particularly beneficial option, allowing for the technical consistency of the entire door system to be maintained.

Item Condition and Service Application

The offered seal is a used item, making it an attractive service alternative for drivers looking for original components within a reasonable budget. This type of part is suitable for both standard repairs after mechanical damage and for replacing a worn seal to improve acoustic comfort and interior protection.

By retaining its factory shape and being intended for a specific mounting location in the rear left part of the body, the component allows for service replacement without the need for modifications to the door or window structure.
