Purpose and Function in the Vehicle

The trunk rubber seal operates in the rear body section, at the contact point between the trunk lid and the car body. Its purpose is to:

• limit the ingress of water and dirt into the trunk space,
• reduce noise and vibrations transmitted from the outside,
• stabilize and seal the edges of the trunk lid,
• maintain the correct closing geometry of the tailgate.

Thanks to its design conforming to factory solutions, this trunk rubber ensures proper alignment of the rear body parts, which translates to comfort during daily use and the vehicle's aesthetics.

Compatibility with BMW Models

This part has been designed for select BMW series models where the rear body structure requires a dedicated trunk sealing strip. Its appropriate profiling and geometry ensure that the part works with factory mounting points and the lid's contour, facilitating installation and preserving the vehicle's original character.

Due to its origin from the BMW group, this trunk rubber seal is particularly recommended for post-accident repairs, replacement of corroded or deformed seals, and comprehensive restoration of the rear body section.

Technical Characteristics and Installation

The trunk rubber seal is made from a material adapted to operate in variable weather conditions typical for vehicle use. The design intended for installation in the rear of the vehicle ensures:

• stable adhesion to the body edges,
• resistance to typical mechanical loads during lid opening and closing,
• maintaining flexibility across a wide temperature range.

When installed correctly, with a clean and degreased contact surface, the seal allows for the restoration of the vehicle's original rear section sealing level. This solution is particularly beneficial for users who want to restore the trunk's original functional properties in a technically correct and repeatable manner.

Item Condition and Service Application

The offered trunk rubber seal is a used part, making it an attractive cost-effective alternative for service and restoration repairs. It is suitable for both replacing worn seals and for rebuilding the rear body section after bodywork and paint repairs. Choosing an original BMW group component helps maintain the vehicle's structural integrity and reduces the risk of fitment issues.
