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

This flapper forms a tight seal and stops leaks instantly. Built from thick flexible rubber that holds up well over time without warping. The universal fit works with most 2 inch flush valves and installs in minutes with no tools needed. Compatible with hard water and chlorine-treated systems. Ideal for fixing slow leaks and reducing water waste. A dependable replacement that outlasts generic flappers.

Best flapper in the game. Easy to install, lasts a long time, seals well, and is about as universal as you can get.

Easy to install, exactly what I needed. Worked right out of the package. Even has a little instructions in there if you need help. Great price as well, would buy again if I ever need another.

Installed a few days ago, works great. Unfortunately (and oddly) the chain was too short. I don't have a special type of toiled or toilet tank, so this was strange. Luckily I could repurpose part of the old chain for this one.One star off for not having two or three more links in the chain.

The toilet flapper is a pretty common replacement item. Over time the rubber/plastic material degrades and tiny leaks develop, causing the "running toilet" syndrome.This Korky flapper includes a couple adjustments if the standard setting allows too much or too little water to flush out.It took just a few minutes to remove the old flapper and set up the new one

Awesome replacement for a leaking stopper valve.This is well made, included plenty of chain to tailor the length to my application. I tried cleaning the old one several times but finally replaced it with this and realized I should have done it much sooner than I did.The instructions included tell you how to make adjustments if necessary (meaning it's shutting too slowly or quickly) but this was perfect on the first shot. This will be my go to when replacing the valves in the other toilets.

Perfect fit! Bought a two pack, each one will last about 5 years so I’m pretty much set. Cost next to nothing. No need to adjust anything, I just measured the old one and made adjustments to the chain. Super easy and simple.

Bought to fix my toilet that was running very frequently, install was easy, and seems to have at least partially resolved the issue, it runs much less frequently, unfortunately every once in a while the toilet does still run, not sure if this is still the issue or if the valve needs adjustment. If I figure out a root cause I'll update this.
