Korky Ultra Standard 2-Inch Universal Toilet Flapper - Long Lasting Rubber - Easy to Install - Made in USA, 100BP (2 Pack)

Used in Kohler toilets to replace failing flappers. Super easy to swap in and they work perfectly. Cheap and easy solution to running toilets. I always keep an extra around, so the multipack is nice to have. Zero running after you replace them and I have yet to need to replace one of these.

Great replacement for an old, worn out flapper that was just stiff and not sealing anymore. Simple to install, fits well, works great!

Worked perfectly, super easy to install.

They are easy to install and fit great on my toilets. They fixed my toilet that would fill at random times. My only problem was that when I first received them the large adjustment ring was impossible to turn. I installed them and the next day I tried again (after they had been in the water all night) and then I was able to easily turn the ring. I really like that I can adjust them for tank level, so I could have a little more water in my flush than there was before (or a lot, but I don't want to waste water).

This Tank Flapper works Exactly as described. Put it in the tank and No more Leaks. Thanks for a Great product

It was a perfect fit and it took me a couple of minutes to install! It seals the flush opening completely and you can easily set how much water you want to drain just by twisting the dial. It seems well made and well designed at a great price, so I’m glad I bought it!

Took me 2 minutes to apply! Easy peasy! Should last awhile, as this is very durable rubber.

Fit my toliet and work great
