Purpose and function of the seal

The presented seal is a component intended for installation in the rear part of the vehicle, in the area where the inner door edge meets the roof. Its purpose is to:

• limit the penetration of rainwater into the vehicle interior,
• reduce wind noise when driving at higher speeds,
• stabilize the door edge relative to the body,
• improve the acoustic comfort of the cabin.

Thanks to its properly selected profile, the seal works in conjunction with the door and roof structure, ensuring uniform pressure along the entire contact length.

Construction and fitment for Audi

The seal belongs to the Doors and door panels group, which means it has been designed to work with the factory Audi door structure. The cross-sectional shape and routing geometry are adapted to the original mounting points, which facilitates installation and allows for maintaining the factory fit of the body components.

The element has a specific placement in the rear part of the vehicle, so when selecting, it is worth paying attention to the mounting side and compatibility with the body version. Proper fitment translates into stable seating of the seal and uniform adhesion to the door and roof surfaces.

Performance parameters and operation

The seal operates under demanding conditions – it is exposed to temperature changes, moisture, and mechanical loads resulting from opening and closing the doors. The appropriate material flexibility allows for:

• compensation for minor body deformations while driving,
• maintaining tightness through multiple door opening cycles,
• limiting the transmission of vibrations from the body to the door edge.

A properly selected rear door seal affects the comfort of daily use, especially in terms of protecting the interior from moisture and improving acoustic insulation.

Condition and benefits of using an original component

The offered item is in used condition, which allows for an economical replacement while maintaining characteristics close to factory standards. Using an original seal from this group ensures:

• shape compatibility with the Audi door and roof line,
• proper fit without the need for modifications,
• the ability to restore the original tightness of the rear door zone.

For users who want to maintain the structural integrity of the body and avoid problems with improper closing or leaks, choosing an original seal is a particularly beneficial solution.
