Purpose and function of the seal

The presented seal is dedicated to the rear right part of the body, where it is responsible for the tightness of the connection between the door and the window. Its task is to limit the ingress of water and dust, as well as to reduce wind noise while driving, which improves acoustic comfort inside the vehicle.

This component also stabilizes the window movement within the door frame, supporting the proper operation of the lifting and lowering mechanism. As a result, it reduces the risk of rattling, play, and unwanted vibrations within the door area.

Construction and technical properties

The seal is made of a flexible rubber material with selected hardness, which allows for an accurate fit to the shape of the door frame and window. The working profile has been designed to:

• maintain stable pressure along the entire length of the edge,
• compensate for minor body deformations while driving,
• maintain flexibility within the typical operating temperature range of the car.

Properly formed edges of the seal support water drainage from the window area, which reduces the risk of moisture inside the door and accelerated corrosion of metal components.

Installation and fit for Ford Focus Mk3

The seal has been designed specifically for the Ford Focus Mk3, ensuring its geometry matches the factory mounting points in the rear right section of the body. Installation involves seating the profile into the provided slots and guides, without the need for structural modifications.

This solution allows for maintaining the factory line of the door and window, and minimizes the risk of leaks resulting from the use of components with an incorrect shape. Proper fit translates into stable window operation and reduction of the "whistling" phenomenon at higher speeds.

Condition of the component and benefits of use

The offered seal comes from dismantling, which means it is a used component, but still functional in the context of its sealing role. Replacing a worn or brittle seal with a functional component of this type allows you to:

• reduce noise coming from the rear part of the body,
• limit the ingress of water and moisture into the door interior,
• improve the comfort of using the rear door window,
• maintain visual and technical consistency with other body components.

For Ford Focus Mk3 owners, this is a practical solution that allows restoring proper tightness without the need to invest in expensive modifications.
