This is the seal that fits under the tank, correct?

Yes, it will fit underneath, but if you have a leaky toilet, it most likely will not solve your issue. It's a real good idea to buy the whole kit for about $15 since there's another seal located just above this one that is causing your leaks.

I was happy with the results
5/5

This part fit and worked perfectly and saved me from having to buy a new toilet. Kohler toilets and parts are so many and it's difficult to tell which one and which part you need unless you've got it in your hands. Glad to hear that.
