Purpose and vehicle placement

The presented seal is designed for installation in the rear left part of the body, in the area of the door and side window. It is responsible for sealing the contact point between the window and the door frame, which is important for both acoustic comfort and protecting the interior from water and external contaminants.

Thanks to its dedicated shape and fitment for the specific Audi model, installation is predictable, without the need for modifications or fitting universal replacements.

Function and benefits of use

The rear left door window rubber seal performs several important operational functions:

• limits water ingress into the door interior and cabin,
• stabilizes the window in the guide during driving,
• reduces wind noise at higher speeds,
• protects the window edge from direct contact with the metal frame.

Replacing a worn or perished seal with a functional component restores the proper sealing of the side body section, which translates into a more comfortable and quieter ride and a lower risk of corrosion inside the door.

Product characteristics and fitment

This is a component designed for Audi vehicles, manufactured in accordance with factory design specifications for the A4 B7 model. The rubber profile, mounting method, and geometry are adapted to the specific body version, ensuring proper adhesion to the door frame and window.

The seal belongs to the group of body components that have a direct impact on the durability of the interior and the comfort of using the vehicle. Using a dedicated component instead of universal solutions allows for maintaining the structural and aesthetic consistency of the side bodywork.

Condition and service application

The offered item is in used condition, making it an attractive service solution for users looking for original components at a reasonable price. This type of part is suitable for post-collision repairs, replacing corroded or leaking elements, and for renovation work within the rear left door area.

It is always worth verifying the selection of the correct seal for a specific vehicle based on the car's technical data and the information contained in the product specification.
