Intended Use and Body Fitment

This seal is designed for the front, right side of the vehicle, specifically the passenger door of the Seat Ibiza 6J. The profile shape and edge geometry are adapted to the factory body lines, maintaining the car's original sealing and appearance after replacement. Installation in place of the original seal requires no body modifications or interference with the door structure.

The component works in conjunction with the factory window guide, keeping the window stable as it opens and closes. The appropriately selected stiffness and flexibility of the material limit window vibrations and minimize the risk of unwanted noises during driving.

Sealing Function and Protection Against External Factors

The external side window seal plays a crucial role in protecting the door interior and cabin from water, dust, and minor contaminants. A correctly selected pressure profile ensures:

• Reduced water ingress into the door interior,
• Decreased wind noise at higher speeds,
• Protection of the window edges from scuffing,
• Stable window guidance at the upper range of its operation.

This improves acoustic comfort in the cabin and reduces the accelerated wear of window regulator components caused by moisture and dirt.

Technical Specifications and Compatibility

The seal is designed specifically for the Ibiza 6J body, taking into account factory installation tolerances. The appropriate width and working profile integrate with the door structure and window line, allowing for even pressure along its entire length. The product belongs to the Seat group, which helps maintain technical consistency with other body components.

The item falls under the Window Seals and Trim category, meaning it is designed for direct contact with the window and varying weather conditions. The construction is adapted for multiple window opening and closing cycles, typical of daily vehicle use.

Condition, Installation, and Service Application

The offered seal is a used part, making it an attractive service solution for situations where the existing seal is mechanically damaged, aged, or deformed. Replacing this component is particularly recommended when symptoms such as increased wind noise from the passenger door side, visible leaks, or issues with smooth window operation occur.

During installation, pay attention to the correct seating of the seal in the door groove and even pressure along its entire length. Careful installation allows for full utilization of its sealing properties and ensures stable window operation in the long term.
