Purpose and Body Fitment

The seal has been specifically designed for the rear right side of the body, which guarantees proper adhesion to the window edge and the door frame or bodywork. This targeted application allows for the preservation of the original body line geometry and reduces the risk of stress on the glass during daily operation.

This component belongs to the Window Seals and Trim group, meaning it is structurally prepared to withstand varying weather conditions, frequent door opening and closing, and exposure to vibrations from the suspension and drivetrain.

Sealing Function and Interior Protection

The primary function of the seal is to maintain proper watertightness between the window and the body. A correctly designed profile limits:

• penetration of rainwater and moisture into the vehicle's interior,
• the formation of unwanted wind noise at higher speeds,
• the ingress of dirt into the space between the window and the frame.

This ensures that the cabin interior remains better protected against corrosion of metal components and degradation of upholstery in the rear part of the vehicle. A properly fitted seal also contributes to acoustic comfort by reducing airflow noise around the rear window.

Technical Characteristics and Installation

The seal is structurally integrated with the rear right side of the body, which facilitates identification of the correct mounting location. Its geometry is adapted to the specific shape of the window frame in the Ibiza 6J model, allowing for even pressure distribution around the entire perimeter.

In practice, installation involves correctly seating the seal in its guide groove and checking for any twists or localized deformations along its entire length. Proper positioning ensures stable window retention and minimizes the risk of leaks at critical corner points.

Component Condition and Service Application

The offered seal is a used part, making it an attractive service solution for situations where a worn or damaged seal needs replacement while maintaining reasonable repair costs. In many cases, using an original salvaged component can provide a better fit than universal profile aftermarket replacements.

This solution is particularly useful for accident repairs, window replacement after mechanical damage, or for eliminating drafts and leaks that may develop over time in the rear right body area.

Compatibility and Additional Information

The seal has an OEM part number and associated interchange numbers, which facilitates verification of compatibility with specific vehicle configurations in manufacturer catalogs and service systems. This allows for precise selection of the part for a given Seat Ibiza 6J unit, minimizing the risk of ordering errors.
