Function and application of the door seal

The presented seal operates at the contact area between the door and the body, creating a flexible barrier between the outer skin and the vehicle interior. Its profile has been designed to:

• limit the ingress of rainwater and mud into the sill area,
• reduce wind noise at higher speeds,
• stabilize the door position relative to the body frame,
• support the maintenance of proper door gap geometry.

As a result, the driver gains more comfortable driving conditions, and the upholstery elements as well as electrical installations in the doors are better protected against moisture.

Construction and fitment for Audi A7 4G

The seal is a component intended for installation on the outer perimeter of the front right door. The cross-sectional shape and length are adapted to the body geometry of the Audi A7 4G generation, which allows for maintaining proper pressure along the entire length of the door perimeter.

This solution enables:

• installation at factory mounting points without the need for modifications,
• maintenance of an even gap between the door and the pillar,
• a visually consistent contact between the door and the body when closed.

Such fitment promotes the preservation of the original door operating characteristics and minimizes the risk of rattles and unwanted noises while driving.

Benefits of using an original Audi seal

Choosing a seal dedicated to a specific Audi model allows you to avoid problems typical of universal solutions. The properly selected profile and hardness of the rubber compound translate into:

• more predictable door closing without excessive force,
• better acoustic insulation of the cabin,
• reduction of air drafts in the area of the pillar and door frame,
• stable performance of the seal over a long period of operation.

For the user, this means higher daily comfort and a lower risk of accelerated corrosion in the sill area and at the door edges.

Characteristics of the used component

The seal comes from dismantling, which in practice means that it is a component with parameters similar to factory assembly, maintaining the construction and geometry intended by the manufacturer. For many users, this is a reasonable compromise between cost and maintaining the original specification of the vehicle.

With proper installation, such a seal allows for effectively restoring the tightness within the front right door, without the need to use replacements with uncertain fitment.
