Audi A5 S5 RS5 F5 Tailgate Boot Trunk Lid Gasket Rubber Strip Seal 8W8827705C

Audi A5 S5 RS5 F5 Tailgate Boot Trunk Lid Gasket Rubber Strip Seal is an original body component designed for precise sealing of the tailgate in the A5, S5, and RS5 F5 generation models. Thanks to its factory profile and carefully selected rubber compound, it provides stable protection against water, dust, and noise, while maintaining the flexibility required for repeated opening and closing of the trunk. It is a practical solution for users who want to restore proper sealing of the rear body section without compromising on fitment.

Purpose and function of the tailgate seal

The presented seal is designed as a perimeter component for the tailgate, responsible for isolating the luggage compartment from external factors. Its profile works with the body edge and the tailgate, creating a continuous barrier that limits:

• the ingress of rainwater and moisture into the trunk,
• the penetration of dust, dirt, and small debris from the outside,
• the transmission of aerodynamic noise and road noise from the rear of the vehicle.

A properly selected tailgate seal helps maintain stable conditions in the cargo area, which is particularly important when transporting electronics, upholstered elements, or other sensitive items.

Construction, material, and fitment

The seal belongs to the body component group of Door seals, but in this case, it serves as a tailgate seal. It is made of flexible rubber material with a specific hardness, which ensures:

• proper pressure against the edge of the tailgate and the body,
• resistance to typical operational loads (repeated opening and closing),
• performance in varying temperatures without excessive hardening or cracking.

As a component from the Audi brand, the seal retains its factory shape and geometry, which translates into predictable installation and proper fitment with the original mounting points on the body.

Benefits of using an original Audi seal

Using an original tailgate seal in A5, S5, and RS5 F5 models allows you to restore sealing parameters close to factory standards. Key advantages include:

• Compatibility with the body structure – the seal profile is adapted to the specific geometry of the tailgate and trunk opening, which reduces the risk of leaks typical of universal-shaped replacements.
• Stable adhesion along the entire perimeter – the appropriate elasticity of the material allows for even pressure, reducing the risk of localized leaks.
• Noise reduction in the cabin – proper sealing of the rear body section reduces noise coming from the trunk and rear bumper area.
• Better protection of upholstery elements and electrical wiring in the trunk against moisture.

Characteristics of the used product and installation aspects

The offered seal is a secondary market component, which allows for economical repair while maintaining the original design. In practice, this means it can be fitted to factory routing and mounting points without the need for body modifications. Installation usually involves seating the seal on the edge of the trunk opening according to the factory path, with attention to:

• correct positioning of corners and profile bends,
• absence of twists or kinks in the material along the perimeter,
• continuity of adhesion along the entire length.

Before installation, it is recommended to clean the body edge of dirt and residue from the old seal, which improves adhesion and the durability of the connection.
