Purpose and fitment for Mercedes Vito W639

The offered window has been designed specifically as a tailgate glass element for the Mercedes Vito W639 model. Its placement in the rear body section ensures proper geometry, correct bending radii, and compatibility with factory seals and tailgate fittings. As a result, installation is predictable, without the need for body modifications or interference with the vehicle's structure.

Technical characteristics of the AS3 tinted glass

The AS3 standard denotes glass with an increased level of tint, intended for areas where thermal comfort and protection against excessive sunlight are a priority. In practice, this translates into:

• reduced amount of sunlight reaching the cargo area,
• limited interior heating of the vehicle while parked,
• better protection of transported cargo from prying eyes,
• a consistent, aesthetic appearance of the rear body section when combined with other tinted windows.

The tinted tailgate window is a functional solution for users who make intensive use of the cargo space – both in private and fleet applications.

Condition, functionality, and benefits of installing used glass

This item comes from a group of used components, which allows for a reasonable repair cost while maintaining factory fitment to the body. A used tailgate window is a particularly beneficial solution in the case of:

• post-accident repairs and mechanical damage to the tailgate,
• replacement after the original glass has cracked or shattered,
• restoring the vehicle to full operational efficiency within a controlled budget.

Using an original glass from dismantling reduces the risk of issues with fitment, leaks, or improper adhesion to the tailgate frame. It is a practical choice for body shops and individual users who expect a predictable installation result.

Application in the rear of the vehicle and operational safety

The tailgate window operates in a demanding area of the body – it is exposed to temperature changes, vibrations, and frequent opening and closing of the tailgate. The appropriate construction of the glass and its fitment to the original hinges and lock contribute to:

• stable seating in the tailgate frame,
• proper cooperation with seals and mounting elements,
• maintaining the tightness of the trunk against water and contaminants,
• maintaining rear visibility in accordance with the purpose of the AS3 tinted glass.

For commercial vehicles such as the Mercedes Vito W639, a correctly selected tailgate window has a direct impact on the comfort of daily operation and the safety of the transported cargo.
