Vehicle Application and Placement

This door seal is designed for installation in the front section of the vehicle body, suitable for both the driver's and passenger's side. Its placement on the vehicle covers the front left and right sides, simplifying part selection for post-accident repairs or replacement of worn-out seals.

This solution allows for:

• consistent restoration of the sealing line on both sides of the vehicle,
• reduction of aerodynamic noise in the front door area,
• maintenance of proper door wing pressure against the body frame.

Technical and Functional Characteristics

The seal is made of flexible rubber material that operates across a wide temperature range and integrates well with the factory door geometry. The cross-sectional profile is designed to ensure even pressure along the entire perimeter, helping to prevent water and contaminants from entering the interior.

Key functional features include:

• stable door wing guidance during opening and closing,
• reduced risk of rattles and resonances around the door edges,
• maintenance of a consistent contact line between the door and the body.

Thanks to its design, which matches factory solutions, the seal is compatible with standard door hinges, locks, and hardware, without requiring body modifications.

Benefits of Use in Mercedes W415

Using this seal in the Mercedes W415 class allows for the restoration of proper door operation when the original part has become worn, deformed, or mechanically damaged. Replacing the seal is particularly important after bodywork and painting in the pillar and sill areas, where the fit geometry directly impacts acoustic comfort.

The most significant advantages include:

• improved cabin sound insulation against wind noise and minor vibrations,
• prevention of moisture ingress around the sills and door upholstery,
• more uniform door pressure against the body, contributing to smoother lock operation.

This part is from the range of original solutions used in Mercedes vehicles, helping to maintain the structural and visual consistency of the entire door area.

Part Condition and Service Application

The door seal is offered as a used part, making it an attractive alternative for service repairs where precise model fit and cost control are important. This type of component is particularly useful for:

• repairs after collisions in the front door area,
• bodywork restoration with a focus on improved sealing,
• restoring original door operating parameters after years of use.

By retaining the original mounting geometry, installation is predictable for workshops, and the risk of fitting issues is minimized.
