Genuine Part Gp1059291 Canister Seal

Easy to install! Solved our issue with toilet refilling ALL the time! The old one was definitely worn and had bubbles. Lots of youtube tutorials on how to change this out. If your kohler toilet is running refilling a lot give this a shot before replacing!

I noticed that my Kohler (K-4436-AA) toilet would start running randomly throughout the day when it wasnt in use. Reading online it seems that a common problem for running toilets is that the canister seal becomes brittle over time and need to be replaced. There are some great videos on YouTube showing the replacement process for the canister flush valve seal. FYI, The replacement seal is a yellow color while the original seal is red, the product packaging shows that new seal is meant to replace the original red seal. During the seal installation, I confirmed that the yellow seal is indeed a perfect replacement for the original red seal. Additionally, since installing the replacement seal I havent noticed the toilet running randomly anymore. Im hoping that this permanently fixes my running toilet if I notice its running again there is most likely another issue causing the water running.

The hardest part of making the replacement was figuring out how to. The gasket, however, leaks after just 12 1/2 months. The original gasket lasted 15 years. Same water. Same usage. Same brand of gasket.

I wanted to have an extra gasket for my toilet.

My in-suite toilet would every so often sound like it a was automatically flushing itself all through the freakin’ night! It kept me awake! I thought it was the flush mechanism so I changed that! Then I observed that it was this O- ring that needed to be replaced! This item is the original Kohler replacement. Don’t buy the fake ones, you’ll just waste your money. These aren’t so expensive anyways. Save yourself the headache and get this original replacement! Getting my well deserved zzzzs!!!

The ring gasket it replaced was allowing a significant leak in my toilet tank despite no apparent damage. This causing my water softener to go through regeneration cycles approximately 3 times as often. I installed the new ring gasket and no more water leakage. Saving $20/month in softener salt.

Exactly what I needed and cheaper than at the hardware store

Easy to install

it fits

I ordered one of these gaskets along with a whole new flush assembly. On a whim, I tried the gasket alone before replacing the whole assembly, and it was less than five minutes start to finish. Great tutorial videos on YouTube. Great update to a bad factory gasket.
