    • Fixed phantom leak
Works as a charm! Product described accurately, replaced worn-out gasket. The gasket fits perfectly on American Standard Model #4149A. Let' see how long this gasket last. Overall, happy with the 1 hour install.

    • 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!

    • Works as well as the original one.
This toilet closet to bowl kit was a perfect fit to repair a leak. I had purchased one from a big box store specifically for my Kohler toilet, but that one leaked. This one appears to be almost exactly as the original equipment one and works perfectly. I highly recommend this particular product vs the big box store brand. ... show more

    • Tank to bowl gasket is formed like the big plastic nut that holds the Flush Value
I liked the fact that the tank to bowl gasket is formed like the big plastic nut that holds the Flush Value to the tank. Feel it's better than universal fit one found at home improvement stores.

    • HARDWARE GREAT....BUT NO 2 INCH VERSION FOR AMERICAN STANDARD TANKS
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
