Purpose and Function of the Door Edge Seal

The presented seal belongs to the Door Seals category and is intended for installation on the rear edge of the door, on either the right or left side of the coupe body. Its functions include:

• sealing the contact between the door and the body in the rear part of the opening,
• limiting the ingress of water, dust, and dirt into the interior,
• reducing wind noise at higher speeds,
• protecting the paint on the door edge from abrasion.

Thanks to its proper profile and material flexibility, the seal works with the door, ensuring consistent pressure along the entire edge length.

Body Compatibility and Vehicle Placement

This component has been specifically designed for Mercedes models with the C117 Coupe body, guaranteeing compatibility with the factory door and body frame geometry. Its placement on the vehicle covers the rear part of the door on both the right and left sides, allowing the seal to be used:

• as a replacement for a worn seal on one side of the vehicle,
• in pairs – for simultaneous replacement on both sides to maintain door operation symmetry.

This precise fit helps maintain a uniform door-to-body contact line, which is important for both sealing and the vehicle's aesthetics.

Performance Characteristics and Installation Benefits

The door edge seal for this model has been developed to work in conjunction with factory hinges and locks, so after correct installation, it does not require any additional structural modifications. The main benefits of using this component include:

• maintaining proper door-to-body pressure in the rear zone,
• improving driving comfort by reducing external noise,
• increasing interior protection against moisture and corrosion of sill elements,
• preserving the consistent door line appearance characteristic of Mercedes coupes.

As a body component, the seal contributes to the functionality of door closing and provides long-term protection for the sill and edge areas.

Component Condition and Service Application

The offered seal is a used component, making it an attractive service solution for vehicle owners looking to restore proper door sealing at a reasonable cost. It is suitable for both standard replacement of worn seals and for post-accident repairs where it is necessary to recreate the factory sealing system in the rear part of the door.

Since it is an original Mercedes part, compatibility with factory mounting points is maintained, which simplifies workshop tasks and reduces installation time.
