• preventing water and moisture from entering the door and cabin,

With its specific profile and precise fit for its mounting location, the seal contributes to maintaining driving comfort and improving the overall refinement of the vehicle body.

Body Fitment and Installation

This seal has been designed for a specific placement on the vehicle – rear, right side. This means its geometry, length, and shape are tailored to the rear right door window of the ML W166 body, which facilitates installation and ensures a factory-like fit.

Proper installation results in:

• uniform pressure of the seal around the entire window perimeter,
• no need for modifications or forcing the part into place,
• stable seating in the door frame, minimizing the risk of looseness and rattling.

Category Characteristics and Role in Body Finishing

This component belongs to the Cladding, Decorative Strips, and Trim category, which includes parts responsible for finishing and protecting critical areas of the vehicle body. For this seal, the key is the combination of protective function with maintaining a cohesive styling line for the door and window frame.

Replacing a worn or leaky seal with a correctly chosen part allows you to:

• reduce the risk of condensation on the rear right window,
• limit air drafts at higher speeds,
• maintain even gaps between the window and the door frame, which enhances the visual quality of the body.

Product Condition and Benefits of Choosing a Used Part

The offered seal is a used part, representing a sensible compromise between cost and maintaining the original geometry and fit characteristic of parts sourced from vehicle dismantling. In practice, this means the possibility of restoring proper sealing to the rear right window without the need to invest in a new component.
