Purpose and body fitment

The presented seal is a component from the Window seals and trims group, designed specifically for the rear left window aperture in the Seat Ateca door. Its placement on the rear left side of the vehicle allows for precise restoration of the factory sealing line in this area of the body, without the need for any modifications to the door or window.

The properly profiled working cross-section of the seal allows for the correct guidance of the window edge during opening and closing, reducing the risk of it rubbing against metal frame elements. This maintains the correct geometry of the window regulator mechanism and the stability of its position in the guides.

Sealing function and interior protection

The window aperture seal plays a key role in isolating the door interior and the cabin from external factors. The properly selected density and flexibility of the material ensure:

• limitation of rainwater penetration into the door interior,
• reduction of wind noise at higher speeds,
• stable adhesion of the window to the frame, which reduces vibrations and unwanted noises,
• better protection against dust and fine contaminants.

Such properties translate into more comfortable acoustic conditions in the cabin and a longer service life for components inside the door, including the window regulator mechanism and electrical wiring.

Component characteristics and installation

The seal is a component sourced from a vehicle, which means it has been previously used but retains the functionality required for further service. Its original Seat origin helps maintain the correct shape, elasticity, and mounting points, which facilitates installation in the factory door holes and clips.

When replacing, it is recommended to:

• thoroughly clean the contact surface in the door frame,
• check the condition of the window edge and guides,
• verify the correct positioning of the seal along the entire perimeter of the aperture.

This approach allows you to fully utilize the sealing properties of the component and reduce the risk of leaks reappearing.

Benefits of using an original Seat seal

Using an original window aperture seal for the rear left door of a Seat Ateca provides a number of practical benefits:

• Factory fit – compliance of shape and length with the door structure, with no need for trimming or adjustments.
• Visual consistency with other body components – maintaining a uniform line of seals around the windows.
• Stable performance parameters within the vehicle's typical operating temperature ranges.
• The ability to restore the original level of tightness after replacing a worn component.
