Purpose and function of the seal

The presented seal is dedicated to the rear right door window in the Passat B7 model and works in direct contact with the window edge. Its tasks include:

• stabilizing the window in the guide during raising and lowering,
• limiting the ingress of water and contaminants into the door interior,
• reducing wind noise at higher speeds,
• protecting the window edge against mechanical micro-damage.

Thanks to its fitment for the specific body model, proper adhesion to the window and door panel is maintained, which is important for both driving comfort and the durability of the window lifting mechanism.

Original origin and fitment

The seal comes from the Volkswagen line, which means maintaining factory geometry, profile, and material hardness. The element was designed for the specific door construction of the Passat B7, therefore:

• it fits the rear right side without the need for modifications,
• it maintains the correct contact line with the window and door frame,
• it enables the proper operation of the factory window regulator.

Such fitment reduces the risk of leaks, rattles, or improper window operation, which often occur with universal parts.

Characteristics of the used component

The seal is offered as a used part, which allows for optimizing repair costs while maintaining the manufacturer's original specifications. In practice, this means:

• factory profile shape,
• maintained compatibility with door mounts,
• possibility of installation as a replacement for a worn or damaged seal.

Replacing a worn element with an original, used seal allows you to restore proper sealing in the rear part of the body without the need to invest in new components.

Importance for comfort and operation

A properly selected lower window seal in the rear right door affects several key operational aspects:

• acoustic comfort – reduction of noise and wind whistling in the rear seat area,
• protection of the door interior – lower risk of corrosion and failure of the electrical installation in the doors,
• stable window operation – smooth guidance of the window in the track, without jamming or play.

For users who pay attention to the refinement of the bodywork and want to keep their car in good technical condition, replacing a worn seal with an original element is a sensible solution.
