Mercedes Exhaust Sealing Ring - Genuine Mercedes 0049979940

Product Information

An exhaust seal ring is a heat-resistant gasket designed to create a tight seal between two sections of the exhaust system, such as between the exhaust manifold and downpipe or other flanged connections. It prevents exhaust gas leaks, reduces noise, and helps maintain proper backpressure for engine performance. Typically made from metal or composite materials, the seal ring endures high temperatures and vibrations while ensuring reliable exhaust flow.

• Loud exhaust noise, especially near connection points.
• Exhaust gas leaks or visible soot marks around the joint.
• Reduced engine efficiency or power, caused by improper exhaust sealing.

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.
