Purpose and function in the vehicle

The sealing moulding from the Door seals category operates in the rear right part of the body, in the immediate vicinity of the door frame. Its task is to:

• maintain the correct position of the door lining and structure relative to the body,
• limit the transmission of vibrations and unwanted play in the mounting area,
• support the tightness of the door circuit through proper seal pressure,
• reduce noise generated during driving and closing the door.

Thanks to its dedicated placement on the vehicle (rear – right side), the element ensures the correct geometry of the door closing and stable operation of the mechanisms in this part of the body.

Benefits of using the original sealing moulding

Using the correct sealing moulding in the rear right door area of a Mercedes brings measurable operational results:

• Better cabin tightness – limiting the ingress of moisture, dust, and gusts of air into the interior.
• Stable door guidance – reduced risk of rattles, knocks, and play while driving.
• Structural consistency – maintaining the factory operating characteristics of the hinges, lock, and other door components.
• Economical repair – the ability to restore proper door operation without interfering with other sub-assemblies.

This solution is particularly useful for post-collision repairs, door panel replacement, or eliminating noises coming from the rear right side of the body.

Installation characteristics

The rear right door sealing moulding in a Mercedes is designed for specific mounts and the shape of the door frame, which facilitates service and shortens workshop working time. A correctly selected element:

• allows for installation without structural modifications,
• ensures repeatable, stable seating on factory mounting points,
• minimizes the risk of leaks resulting from profile mismatch.

Thanks to this, the repair of the rear right door area can be carried out in an orderly manner, maintaining the vehicle manufacturer's standards.

Condition of the element and practical application

The offered seal is a used component, which in service practice often represents a reasonable compromise between cost and functionality. This type of part will work well in:

• post-accident repairs of the rear right part of the body,
• removing leaks and noises in the door area,
• restoring proper closing and guidance of the door after previous bodywork interventions.

For workshops and individual users, this means the possibility of performing a technically correct repair while maintaining a favorable service budget.
