Korky 2017BP Standard 2-Inch 2X Ultra High Performance Universal Long Lasting Rubber-Easy to Install-Made in USA Toilet Flapper, 1 Count (Pack of 1), Red

Super quick install (minutes). Fits Kohler k-4620 perfectly. Instructions for settings are perfect. The Band setting, white circle is open, the black circle is closed (I missed that on the chart). Made in USA. Loved other Korky products (fill valves), and decided to try the 2x lasting for just a few dollars more. Time will tell, 10 year warranty (!) Edit: Weird to rave about a toilet flapper, but this is the best flapper in the house. The water saving feature setting works perfectly without needing a second flush. When other flappers go bad, I will be replacing with Korky!

Works well. Better price than my local box store. Seems to be good quality and sturdy construction.

This did a great job in stopping a slow leak on our toilet bowl. Like the fact that it has adjustments that can be made which helps the device in creating a seal. I would not buy any other very well designed and super easy to install. Perfect fit and worth every penny.

Easy to install to replace years old flapper.

I have tried a lot of brands - Fluidmaster etc. and only the Korky brand works consistently and durably. Period. Excellent product. Others seemed to work but after a few days were leaking. Korky is worth every penny. This is not a paid endorsement.

Extremely easy to install. Didn’t even need to close the toilet valve. Slipped off one side of the old flap and moved it over slightly as I put on one side of the new flap. Did the same with the other side and it was on. I counted the number of loops in the chain of the existing old flapper so the length would match up. Removed the old chain and clipped on the new. Amazed. First time doing this. The best part was it works. Only suggestion is make sure you buy the correct size flapper comes in 2” and 3” and read the back of the package to turn the dial to the correct air hole for your toilet as instructed.

This is a quality product at a reasonable price. I recomend.

Perfect universal flapper. Spend the extra money and do it right with a 10 year flapper. The other flappers that are 1 year or 5 year are junk. This one is the real deal.

It works perfectly

The best, most flappinest flapper available

I have Toto Toilets. Replacement parts are too expensive. This worked perfect fraction of the cost.

This is the flapper you want! It’s universal, 2” flapper with detailed instructions on how to properly check that your toilet is being filled to the right level, it’s adjustable. Perfect, thanks

Fits perfect
