Purpose and technical function

The rear right door sealing strip has been designed specifically for the body construction of the Mercedes C-Class W204 generation. Its profile matches the door geometry, ensuring:

• controlled airflow in the door area,
• prevention of water and dirt ingress into the interior,
• reduction of vibrations and rattling resulting from door operation,
• stable guidance of the door edge relative to the bodywork.

Its placement on the rear right part of the vehicle allows for precise replacement of the component without interfering with other sealing zones, which facilitates service and reduces workshop time.

Installation parameters and fitment

The component belongs to the Door seals group, meaning its design is focused on the requirements of tightness and flexibility in the area of the moving door leaf. The black color facilitates integration with factory linings and masks potential signs of wear, maintaining a consistent look for the door edge.

The seal is intended for installation on the rear right part of the body, so during replacement, it is worth paying attention to:

• correct positioning of the profile relative to the door edge and pillar,
• even pressure along the entire length,
• cleanliness of the contact surface before installation.

This approach minimizes the risk of leaks and allows for full utilization of the component's sealing properties.

Visual and functional characteristics

The black shade of the seal is neutral and technical, making it compatible with both light and dark door upholstery. The subdued color scheme ensures that the component remains virtually invisible when the door is closed, while providing an aesthetic finish to the edge.

As a part from the Door seals group, the product contributes to:

• acoustic comfort inside the cabin,
• protection against moisture in the sill area and lower parts of the upholstery,
• reduction of corrosion in the area of the door edge and adjacent components.

This is a practical solution for users who want to restore the factory sealing properties of the doors in their Mercedes C W204 without interfering with other body elements.

Condition and service application

The component comes from the secondary market, which allows for an economical replacement of the seal while maintaining compliance with the factory design. For workshops and individual users, this means the possibility of matching a part consistent with the original geometry without the need for door modifications.

The rear right door sealing strip will work well both for standard replacement of a worn element and for body and paint work where restoring tightness after body repair is required. Precise fitment to the rear right zone facilitates installation and reduces the risk of subsequent corrections.
