Purpose and vehicle placement

The presented seal is designed for installation on the rear door on the left or right side of the Mercedes ML W164 generation model. The profile design is matched to the geometry of the door opening, which allows for proper adhesion to the bodywork and the door frame.

Its placement in the rear part of the body means the component is responsible for:

• limiting air drafts at higher speeds,
• reducing road noise and wind noise,
• protecting the door edge from direct contact with the bodywork.

Sealing function and acoustic comfort

The door seal plays a key role in maintaining proper cabin tightness. The appropriately selected cross-section and material flexibility allow for even pressure of the door against the body, which translates into:

• efficient water drainage from the sill and pillar area,
• limiting the ingress of moisture into the interior,
• stable door closing without the need for excessive force.

By maintaining proper tightness, acoustic comfort is also improved – the cabin is better insulated from outside noise, which is important both in daily city driving and on the road.

Benefits of using an original Mercedes seal

Choosing a component from the Mercedes brand means maintaining factory parameters for fit and door operation. The most important advantages include:

• a profile consistent with the ML W164 body construction,
• proper guidance of the sealing line along the entire door perimeter,
• reducing the risk of rattles, squeaks, and play resulting from ill-fitting replacements.

The element from this group will work well both when replacing a single seal and during broader work related to refreshing the rear part of the body, e.g., after body and paint repairs.

Characteristics of the used product

The offered seal is a used component, which in practice means it comes from vehicle disassembly and may show signs of normal wear. This type of component is a good choice for drivers looking for a solution with a favorable price-to-functionality ratio, while maintaining the original design and geometry of the part.

Before installation, it is recommended to perform a standard check of the working surface condition and ensure proper seating in the door slot to fully utilize the sealing properties and avoid leaks resulting from incorrect installation.

Modernization expansion and additional materials
