Purpose and vehicle placement

The presented seal is designed for installation in the front part of the body, on the left side of the vehicle. It is responsible for sealing the contact point between the side window and the door frame, which is important both for protection against water and dust and for stable window guidance in the track.

Thanks to its proper fit to the geometry of the driver's door, this component supports the correct operation of the window lifting mechanism and reduces unwanted vibrations when driving at higher speeds.

Technical and functional characteristics

The seal is made of flexible rubber material, selected for its resistance to variable temperatures and typical operational loads. The profile design was developed by the vehicle manufacturer, which results in:

• stable adhesion to the door frame and window edge,
• reduction of air drafts in the area of the A-pillar,
• reduction of cabin noise during highway driving,
• protection against moisture ingress into the door interior.

The properly selected hardness of the rubber compound helps maintain its shape over a long period of use, while maintaining the required flexibility when opening and closing the door.

Benefits of using an original Ford seal

Using an original Ford component allows you to maintain the factory fit of the door and window, without the need for adjusting or trimming the profile. This solution is particularly beneficial for post-collision repairs, door replacements, or when removing the effects of wear and tear on an old seal.

The main advantages include:

• factory geometry matched to the specific body model,
• consistency with other door trim elements,
• reduced risk of leaks in the front side window zone,
• maintaining acoustic and functional comfort at a level close to the factory configuration.

Component condition and service application

The offered seal is a used part, which makes it an attractive solution for budget-friendly service repairs or restoring vehicle functionality after mechanical damage. For workshops and individual users, it represents a practical alternative to new parts, allowing for compliance with the original door construction.

Selecting the right component is facilitated by the manufacturer's markings and interchangeable numbers assigned to the product, allowing for precise verification of compatibility with a specific version of the fourth-generation Ford Mondeo.
