BMW Door Mirror Seal - Genuine BMW 51337120659

Product Information

A door window seal (also called a weatherstrip or window channel seal) is the rubber lining that fits around the edge of a car’s door window. Its main purpose is to create a tight seal between the glass and the door frame, preventing water, wind, and noise from entering the cabin. It also helps keep the window stable while moving up and down.

• Water leaks inside the cabin during rain or car washes due to gaps or cracks in the seal.
• Wind noise or whistling at higher speeds as air passes through worn or loose seals.
• Difficulty operating the window, with glass binding, rattling, or not aligning properly in its track.

About Genuine BMW

The original parts used by BMW to build your car are available as replacement parts under the “Genuine BMW” brand. When ordering a Genuine BMW part you are guaranteed to get the same part that you would pick up from your local dealerships part department. Genuine BMW parts have been built to BMW’s stringent standards and are the same quality of the original parts used to build your Ultimate Driving Machine.

You may not realize this, but the parts that make up your BMW are not necessarily manufactured by BMW. No cause for concern, as BMW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for BMW 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 BMW parts box and find an OEM branded part inside, simply with the addition of a BMW 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.
