  • Good, quality product for 3" toilet tanks

Quality product. Bought as spare - gasket is molded to fit the large nut for a tight fit - the bolt gaskets are very good also, giving a better, more positive seal than flat rubber washers. Don't need to tighten alot!

Hardware works for my American Standard toilet, which includes a washer with sleeve, that anchors the toilet thru the hole much better those without the sleeve. But it didn't include a 2 inch connection, inaddition to the 3 inch, since I found out mine was a 2inch, which I didn't find out until installation ( which I got then separately from another brand.) That's why I gave it a 3, instead of 5. Should have noted another version, with 2 inch. ... show more
