Purpose and vehicle placement

The presented seal is designed to work in the front right door area, at the contact point between the door panel and the bodywork. It is responsible for:

• sealing the door perimeter at the contact point with the body,
• reducing air drafts at higher speeds,
• limiting the ingress of water and dirt into the interior,
• stabilizing the door position relative to the frame.

Thanks to its proper fit to the Mercedes R170 body structure, the seal works with factory mounting points, which facilitates installation and allows for maintaining the original door fitment geometry.

Technical and functional characteristics

The seal belongs to the Door seals category, meaning it has been developed to operate in variable weather conditions and during repetitive door opening and closing cycles. The flexible profile ensures:

• even pressure along the entire door perimeter,
• compatibility with the factory body line,
• proper interaction with the window and door lock.

The appropriate cross-sectional geometry of the seal also helps reduce vibrations transmitted from the body to the door, which positively affects the overall operation of the door assembly.

Benefits of using an original Mercedes seal

Using a dedicated seal in the Mercedes R170 model allows for maintaining factory tightness and driving comfort parameters. Compared to universal replacements, a properly fitted component:

• minimizes the risk of leaks in corners and near pillars,
• reduces the need for additional hinge and lock adjustments,
• ensures a visually consistent seal line around the door.

For the user, this means stable door closing, predictable behavior during temperature changes, and more comfortable acoustic conditions inside the vehicle.

Condition of the item and service application

The offered seal is an item from the used body parts group, making it an attractive solution for accident repairs, replacing worn seals, or restoring tightness in older vehicles. In practice, it will work well both for local front-right repairs and for broader restoration work within the passenger door area.
