Purpose and function of the seal

The described seal is a component mounted in the rear part of the body, on the right side, on the inner side of the window. Its task is to stabilize the glass pane in the frame and maintain the tightness of the glass-to-body connection. Thanks to its specifically designed profile, the seal helps to limit the ingress of water, dust, and air, which translates into smoother operation of the window mounting and better acoustic comfort in the cabin.

Benefits of using an original Skoda seal

Using an original part from dismantling allows for maintaining the factory fit and geometry of the rear window. In practice, this means:

• proper positioning of the glass in the frame without stress,
• maintaining tightness in the rear body area,
• reduction of rattling and resonance coming from the window area,
• aesthetic finishing of the glass edge from the interior side.

For the user, this translates into stable rear window operation and the maintenance of predictable operating conditions during daily driving.

Installation characteristics

The seal is prepared for installation in a specific location on the body – in the rear part of the vehicle, on the right side. This ensures the correct geometry and profile shape are maintained, which facilitates service work and shortens replacement time. The element is intended for Skoda vehicles of the third-generation Octavia family, allowing for a direct fit to the factory window frame without the need for modifications.

Application of the used part

Choosing a used rear window seal is a reasonable compromise between cost and functionality. The component from dismantling, originating from a vehicle of the same make and generation, retains its original shape and operating parameters, while simultaneously allowing for a reduction in repair costs compared to a new part. It is a practical solution for post-accident repairs, window replacement, or when eliminating leaks in the rear body area.
