Purpose and function of the component

The described sealing moulding operates in the rear right area of the body, within the door and side window zone. Its purpose is to:

• limit the ingress of water and contaminants into the door interior,
• stabilize the window edge during raising and lowering,
• reduce wind noise and unwanted glass vibrations,
• maintain an aesthetic contact line between the window and the door frame.

Thanks to its fitment for the specific Mercedes body model, the moulding works with the factory window lifting mechanism, which promotes smooth operation and reduces the risk of jamming.

Construction, color, and fitment

The moulding combines the function of a seal and an external window edge finish. The silver color is characteristic of many Mercedes trim levels and allows for consistency with other decorative body elements. Its placement on the vehicle in the rear right part of the body ensures compatibility with the factory door geometry, which translates into proper adhesion to the window and bodywork.

The original origin from the Mercedes brand means maintaining the correct sealing profile and appropriate rigidity of the moulding, which is important for both tightness and durability after installation.

Condition, application, and benefits of replacement

The item is offered in used condition, which allows for an economical replacement of a damaged or worn moulding while maintaining the manufacturer's original specifications. Replacement is particularly important in situations where:

• water leaks or traces of leakage appear on the window edge,
• there is increased wind noise at higher speeds,
• the old moulding is mechanically damaged or deformed,
• it is necessary to restore the aesthetics of the side body line after body and paint repairs.

Using an original sealing moulding helps maintain proper window guidance, reduces the load on the lifting mechanism, and promotes longer, trouble-free operation of the entire door assembly.

Why choose original Mercedes Door seals

For components such as window mouldings and seals, precise fitment to the specific body is crucial. Original Mercedes solutions ensure:

• shape compatibility with the factory door frame and window profile,
• appropriate hardness and flexibility of the sealing material,
• visual consistency with other mouldings and side finishes,
• easier installation thanks to the preservation of factory mounting points.

If you are planning a comprehensive repair or upgrade of the door area in your Mercedes and need other components from the same group, such as additional mouldings, perimeter seals, or window edge finishes, check the available parts in the Mercedes Door seals category.

Practical installation and maintenance tips

When replacing the sealing moulding, it is worth paying attention to the condition of the window edge and the contact surface in the door. Thorough cleaning and inspection for any signs of corrosion help to fully utilize the properties of the newly installed component. It is also recommended to:

• check the operation of the window lifting mechanism after installation,
• check for leaks after the first wash or heavy rain,
• periodically clean the window edge at the point of contact with the seal.

Such an approach promotes the maintenance of stable window operation and reduces the risk of accelerated wear of the sealing material.
