Purpose and function of the tailgate seal

The presented seal is a component mounted in the rear part of the body, along the perimeter of the tailgate. Its task is to maintain controlled tightness of the connection between the tailgate and the body, so as to:

• limit the ingress of rainwater and moisture into the luggage compartment,
• reduce the penetration of dust and dirt from the outside,
• lower the level of noise and vibrations transmitted into the vehicle interior.

Thanks to the appropriately selected cross-section geometry and the flexibility of the rubber, the seal works with the factory hinges and the tailgate lock, ensuring even pressure along the entire perimeter.

Construction and material properties

The tailgate seal is made of flexible rubber material, adapted to work in variable weather conditions. The design provided by the vehicle manufacturer ensures:

• stable adhesion to the body edge without the need for additional modifications,
• resistance to typical operational loads, such as frequent opening and closing of the tailgate,
• shape retention across a wide temperature range.

The appropriate seal profile supports proper water drainage outside the trunk outline, which reduces the risk of dampness in the upholstery and equipment elements. Factory fitment for Audi minimizes the risk of leaks typical of universal-shape replacements.

Benefits of using an original Audi seal

Using an original rubber tailgate seal in the Audi A5 8T allows for maintaining sealing parameters close to factory standards. In practice, this means:

• more predictable body behavior in rain and during pressure washing,
• better protection of electrical components and upholstery in the luggage compartment,
• reduction of unwanted rattles and squeaks resulting from clearances between the tailgate and the body.

For users who care about the condition of the body and acoustic comfort, replacing a worn seal with a component consistent with the model's design is a simple way to improve daily operation. Precise fitment to the body facilitates installation and shortens service time.

Installation characteristics and application

The seal is intended for installation in the rear part of the vehicle, in the area of the Audi A5 8T tailgate. The design intended for this model allows for:

• installation in place of a worn component without bodywork modifications,
• maintaining the original contact line between the tailgate and the body,
• proper cooperation with the factory lock and hinges.

The product comes from the Window seals and trims segment, which means it was designed for operation in critical body zones exposed to contact with external factors. The used condition allows for an economical replacement of the component while maintaining the original design specification.
