Purpose and function of the seal

The presented seal is designed specifically for the front right door of the Volkswagen Passat CC, taking into account the factory shape of the door frame and the geometry of the window. The component is mounted from the inside, creating a precise guide slot for the window and a barrier against water and contaminants entering the door interior.

Thanks to the properly selected rubber profile and stable support structure, the seal helps to:

• reduce air drafts at higher speeds,
• decrease the penetration of outside noise into the cabin,
• protect the window lifting mechanism from excessive contact with moisture,
• maintain proper vertical window guidance, which reduces play and unwanted vibrations.

Construction and body fitment

The inner window seal for the front right door has been manufactured as a component dedicated to a specific body model, which ensures factory fitment with the door frame. The working profile of the seal is matched to the edge of the glass and the inner part of the door panel, so no additional modifications or adjustments are required after installation.

Properly shaped working edges minimize friction during window movement while maintaining stable pressure against the glass. This allows for smooth operation of the lifting mechanism without overloading the guides and cables. Using an original seal reduces the risk of squeaking, rattling, and leaks typical of poorly fitted replacements.

Benefits of using an original seal

Choosing an original door seal for the Passat CC is a beneficial solution both in terms of technical performance and operation. The component retains its factory geometry, which translates into:

• stable window guidance – lower risk of misalignment and jamming during raising or lowering,
• better acoustic sealing – reduction of wind noise and ambient sounds,
• protection of the door interior – reduced accumulation of water and dirt in the window mechanism zone,
• maintaining a consistent interior appearance – proper adhesion to the upholstery and door frame.

Using original sealing components is also important for the future resale of the car – maintaining factory-quality door and window assembly is often noticeable during vehicle inspections.

The offered seal belongs to the Door seals group and is intended for installation on the front right side of the vehicle. As a used part, it comes from disassembly, which allows for maintaining the original design specifications proper for this model.
