Seems strong and sturdy and should fit perfectly when the time comes to actually use it.

I tried cheap imitations of the tubber seal and they all failed to stop the slow leak. Once I used the genuine Kohler gasket the problem was solved!

Performs as advertised. It was also very easy to install. Couldn't be happier.

I had to buy a replacement seal after the original seal failed within a year.

Seal had installing instructions on package and were easy to follow. Installed seal very quickly & easily.
