Purpose and function of the component

The presented seal is dedicated to the rear right body zone and works with the side window in the passenger door. Its tasks include:

• sealing the contact point between the window and the door panel from the outside,
• draining rainwater away from the door structure,
• protecting the window lifting mechanism from moisture and dirt,
• stabilizing the window edge during regulator operation.

Thanks to its fitment for a specific body model, the seal maintains the correct geometry, which translates into proper adhesion to the window and the bodywork.

Original Volkswagen fitment

The seal comes from the Volkswagen range, which means it maintains factory parameters for shape, flexibility, and profile rigidity. Original manufacturing minimizes the risk of leaks, rattling, or improper window operation, which often occur with aftermarket parts featuring inaccurate profiles.

The component is intended for installation in the rear right part of the vehicle; therefore, when selecting, it is worth paying attention to the installation side and body type to ensure full compatibility with the door frame and window guide.

Condition, installation, and service aspects

The product is in used condition, which allows for an economical replacement of a damaged or worn seal while maintaining the manufacturer's original specifications. Before installation, it is recommended to perform a standard inspection of the working surfaces, mounting slots, and the cleanliness of the water drainage channels in the door.

Replacing the seal usually does not require interference with the door structure; however, it should be performed while ensuring the profile is correctly seated on the sheet metal edge and pressed evenly along its entire length. A properly installed component helps reduce wind noise at higher speeds and lowers the risk of window fogging from the inside.

Benefits of using a dedicated seal

• Better window system tightness – limiting the ingress of water and dirt into the door interior.
• Protection of internal mechanisms, such as guides and the window regulator.
• Improvement of cabin acoustic comfort by reducing wind noise.
• Aesthetic finish of the window edge and door, consistent with the body line.

Selecting the correct seal for the specific side and rear section of the vehicle helps avoid problems with window closure and unwanted noises while driving.
