Purpose and fitment for Audi S4 B7

The presented gasket is dedicated to the rear right door wing of the Audi S4 B7 generation. The profile shape and cross-section geometry are adapted to the factory contour of the door frame, which allows for maintaining proper pressure against the bodywork and quick seating in the original mounting channel.

Thanks to a design consistent with the manufacturer's solutions, the component works with the factory hinges, lock, and door window, ensuring stable door edge guidance and proper closing without the need for additional modifications.

Sealing function and acoustic comfort

The rubber gasket for the rear right door wing plays a key role in protecting the interior from external factors. It is responsible for:

• limiting the ingress of water and moisture into the sill area and the cabin interior,
• reducing wind noise at higher speeds,
• minimizing vibrations and rattles resulting from door operation,
• maintaining a stable contact line between the door and the body.

A properly selected gasket helps maintain acoustic and operational comfort, which is particularly important in a sports-utility model like the Audi S4 B7.

Component characteristics and installation

The rear right door wing gasket is made of flexible rubber material, which allows for adjustment to bodywork embossments and compensation for minor deviations resulting from body flex. The gasket profile has been designed to ensure proper pressure against the door frame when closed, without putting excessive load on the hinges.

The element comes from the Doors and door panels group, which means it has been developed to work with other components in this area – the skin, frame, lock, and window. Installation involves seating the gasket in the factory guide channel, which, when following the correct work sequence, allows for the efficient restoration of door sealing.

Condition, origin, and service application

The offered element is in used condition, making it a practical service solution for Audi owners who want to restore proper sealing of the rear right side of the body without having to resort to more expensive solutions. This type of component is particularly useful for:

• repairs after collisions in the rear right body area,
• eliminating leaks and seepage in the rear door area,
• reducing cabin noise resulting from the wear of factory gaskets,
• renovation and maintaining tightness in vehicles operated in varied weather conditions.

Choosing an original door gasket from this group allows you to maintain technical consistency with other body elements and keep the vehicle's proper performance parameters.
