Purpose and function of the seal

The presented quarter window seal has been designed specifically for the Mercedes GL X164 generation and is mounted in the rear part of the body on the left side. It is responsible for a tight connection between the glass and the bodywork, which is important both for protection against moisture and for the stability of the glass itself while driving. A properly selected seal reduces the risk of window fogging, air drafts, and unwanted noises coming from the area of the rear side window.

This element belongs to the Car Windows group, but it plays a key auxiliary role – it is responsible for maintaining the correct pressure and flexible adhesion of the glass to the body frame. Replacing a worn or perished seal with an original component allows you to restore factory sealing parameters without the need for structural vehicle modifications.

Technical characteristics and fitment

The seal is made of flexible rubber material, which provides adequate elasticity and resistance to typical operational stresses, such as temperature changes, UV radiation, or body vibrations. The blue color used facilitates the identification of the element during assembly and disassembly and may correspond to the factory finish of a specific trim version.

Placement in the rear zone, on the left side of the vehicle, requires maintaining the correct orientation of the seal relative to the window frame and bodywork. The original profile geometry facilitates the correct seating of the element, and the properly profiled edges work with the quarter window, ensuring even pressure around the entire perimeter. As a result, installation is predictable, and the risk of leaks after replacement is minimized.

Condition, origin, and benefits of use

The offered seal comes from dismantling and is a used item, which allows for combining an attractive price with the preservation of the manufacturer's original specifications. Unlike generic replacements, the factory component ensures a proper fit to the window frame and bodywork, without the need for modifications or additional adjustments. This is particularly important in the case of large SUVs, where the surface area of the windows and the length of the seals have a direct impact on acoustic comfort.

Using the original rear side window seal on the left side allows you to:

• restore the tightness of the glass-to-body connection in the rear part of the vehicle,
• limit the ingress of water and moisture into the interior,
• reduce noise and wind roar in the cabin,
• maintain the aesthetic appearance of the window line in the Mercedes GL X164.

Selection by OEM number and purchase safety

To ensure full compatibility with a specific trim version, it is worth verifying the part's compliance by the OEM number or interchangeable numbers assigned to this model before purchasing. In case of doubt, the vehicle's VIN number will be helpful, which allows for the unambiguous matching of the correct variant of the rear side window seal. A detailed, practical procedure guide can be found in the article Guide: how to choose the right car part by VIN and OEM number, which describes step-by-step the verification method and a list of questions worth asking the seller.
