There are 2 rubber washers. One on the inside of the wheel and one outside. The outside one also has a plastic washer that is placed between the rubber washer and the threaded collar that holds it all in place. If those aren't on the ones you bought, you may be able to source something at an auto parts store, hardware store or you can call Shrader to see if they sell those separately. Make sure to tighten the collar down really well or the air stem valve may float around on you inside the stem itself.

This current item on eBay pretty much looks like mine:

Yes, they look like that. You can buy a service pack at most auto parts stores that contain the washers and collar, etc for a few dollars. Bring the sensors with you to make sure the replacement parts fit. Schrader is one of the OEM suppliers to Mercedes. I have the Schrader units in my summer tires. I bought them new.
