Product Information

Mercedes-Benz Rear Window diagram for CL63 AMG, CL65 AMG, CL600, CL550

The quarter glass seal is a molded rubber weatherstrip designed to create a watertight and airtight barrier around the vehicle’s fixed rear side (quarter) glass. It prevents water leaks, wind noise, and dust intrusion while helping to stabilize the glass within the body frame. Made from durable, UV- and weather-resistant rubber, the quarter glass seal also contributes to cabin comfort and preserves the vehicle’s overall fit and finish.

• Water leaks or moisture inside the cabin – a common sign of a deteriorated or misaligned seal.
• Increased wind noise at highway speeds – caused by gaps or hardened rubber.
• Visible cracks, shrinkage, or deformation – indicates aging material and reduced sealing performance.

About Genuine Mercedes

The original parts used by Mercedes Benz to build your car are available as replacement parts under the “Genuine Mercedes Benz” brand. Manufactured under the direction of Mercedes Benz, expect excellent quality and a premium price since these parts are exclusively available through the Mercedes Benz Dealership network.

You may not realize this, but the parts that make up your Mercedes-Benz are not necessarily manufactured by Mercedes-Benz. No cause for concern, as Mercedes-Benz designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for Mercedes-Benz for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine Mercedes-Benz parts box and find an OEM branded part inside, simply with the addition of a Mercedes-Benz logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
