Purpose and Body Fitment

The presented glass has been specifically designed for Mercedes Vito and Viano models of the W639 generation, intended for the right rear part of the body. Its placement on the vehicle is clearly defined, which simplifies component selection during accident repairs or replacement of a worn side window.

As a body component, the glass works with factory seals and mountings, ensuring bodywork seal integrity and correct glazing geometry. This allows for the maintenance of a consistent vehicle side profile and proper operation of door mechanisms and adjacent elements after installation.

Characteristics of AS3 Tinted Glass

Glass designated with AS3 class is a solution used in areas where stronger tinting is permitted. In practice, this means:

• increased protection against excessive interior sunlight,
• reduced heating of the passenger and cargo space,
• more discreet interior visibility from the outside,
• a consistent, aesthetic appearance of side glazing in versions with factory tinting.

Tinted body glass improves the travel comfort of rear-row passengers and contributes to more stable air conditioning performance, which is particularly noticeable in vehicles used for multiple passengers or deliveries.

Benefits of Using Original Mercedes Glass

Original body glass dedicated to the Vito and Viano W639 ensures factory fitment to the body, which translates to proper alignment with the window frame and maintained seal during operation. Using a component from the same product line as the original factory-fitted part minimizes the risk of installation problems and reduces the need for additional modifications.

The product comes from the used car glass segment, which allows for a reduced repair cost while maintaining the vehicle's original specifications. This solution is particularly beneficial for accident repairs where both compliance with the factory design and a rational approach to the service budget are important.

Condition, Application, and Service Aspects

The glass is offered as a used item, which in practice means the possibility of an economical replacement of damaged glazing while maintaining appropriate performance parameters. This type of component is suitable for both fleet repairs and individual projects where the priority is to combine functionality with cost control.

For installation, it is recommended to use appropriate sealing materials and to have the work carried out by a workshop experienced in fitting glazing to van-type bodies. Properly installed body glass maintains the rigidity of the side structure, seal integrity, and proper water drainage from the window frame area.
