Rated 4.0 out of 5.0 by Toiletfixerman Needs a trim, then seems to work
Contrary to the directions and some previous reviews, the flapper assembly no longer can be unscrewed. So, as others have said, take a sharp utility blade and trim off the inner edge of the circle. Seems to do the trick; definitely fits. American Standard must have changed their design and the aftermarket didn't catch up yet (the affected toilet was installed new 1 year before the old seal began leaking).

Rated 5.0 out of 5.0 by Graniteguy33 Easy fix with this replacement flapper seal!
Fits perfectly! However the product description should list exact dimensions of flapper seal (inside and outside diameter) to insure that you are purchasing the correct size seal for your application. In my case the original seal disappeared down the flapper seal hole (I presume?) and I had nothing to measure against when ordering except the rough dimensions of the remaining flapper assembly. FYI, my original seal was black in color and this replacement seal is blue.

Rated 5.0 out of 5.0 by Me So far so good
. A little tight to install but seals well. Can't beat it for the price and senseless to replace the whole flapper if you just need the washer. Just wish hardware stores stocked them these days, surprised that I had to order!
