Here is a Shark nv352 vacuum cleaner motor with a broken gasket:
It seems to be 3 3/4" in diameter. I'm not sure of the material. It is not currently pliable.
The motor works perfectly well, but the vacuum cleaner started making a huge whining noise. I think this gasket probably dampens vibration?
Anyway, is it possible to buy a replacement gasket? Is it standard? What is it made of?
It seems to be somewhat stuck on. I imagine I can pry the rest of it off with a screwdriver, but I don't know if I can get a replacement.
I can get a replacement motor on ebay. Do I have to? The motor itself works perfectly well.
EDIT: Is this a gasket, or an o-ring, or something else? It seems to have some depth and shape to it, and I'm noticing youtube videos about cork gaskets seem to indicate they are flat.
