Application and body fitment

The presented window belongs to the Automotive Glass category and is intended for installation in the rear right side of Mercedes Vito and Mercedes Viano vehicles of the W639 generation. Its placement on the passenger side allows for precise fitment into the factory mounting opening, which facilitates the work of body shops or services specializing in vehicle conversions and body repairs.

The original geometry of the glass ensures proper adhesion to seals and body elements, which reduces the risk of leaks, wind noise, and unwanted vibrations while driving. This is particularly important in commercial and passenger vehicles that frequently cover long distances under full load.

Characteristics of AS3 tinted glass

The AS3-rated tinted glass has been designed to increase passenger comfort in the rear of the vehicle. This type of window:

• reduces the amount of sunlight entering the interior,
• limits cabin heating on sunny days,
• improves privacy for passengers and transported cargo,
• supports the protection of interior elements against fading.

As a result, the rear zone of the vehicle becomes more functional for both family use and professional transport, where protecting goods from excessive sunlight is important.

Condition of the item and benefits of choosing a used part

The offered window is a used component, which allows for an economical vehicle repair while maintaining the manufacturer's original specifications. Choosing this solution is particularly beneficial when you want to maintain a consistent appearance of the side bodywork and match the tint shade to the other windows in the vehicle.

A used factory window is also a good compromise between repair cost and quality – the component comes from production intended for the Mercedes brand, which helps maintain proper body rigidity and the correct operation of seals and mounting strips.

Professional selection and OEM compatibility

To ensure that the window will be properly fitted to your Vito or Viano, it is worth paying attention to the OEM part number and available interchangeable numbers, which you can find in the technical specifications section. This helps avoid installation problems and guarantees compliance with the factory body construction.
