Genuine Part Gp1059291 Canister Seal

If you are worried this wont fit, dont be. It replaces the red one and appears to be of better quality. It was easy to install and works perfectly. Will purchase again (hopefully, not too soon)…

I have a low-flow Kohler toilet that had a phantom flush. That is where your valve seal has gotten old and the water leaks out slowly. All of a sudden you hear the toilet start to fill again all by itself in a pattern. That is called the phantom flush. A very slow leak into the bowl that finally results in the water level getting so low in the tank that it flushes itself. Did some research and found out it was time to change the valve seal. Seems like they only last a couple of years (less if you use chemicals in the tank itself for cleaning). Bought this inexpensive little piece. Looked on YouTube for a video on replacing a canister flush valve seal. And voila! Toilet fixed and no repairman bill. Bought 2 of these at the same time so Id have a spare a couple of years down the road when this one fails. $7 is much better than a $75 plumber call! Do it yourself - you can do it if I did!

it fits

I wanted to have an extra gasket for my toilet.

I’ve only had this installed for a week & it’s working great! I am pretty optimistic that it will do better than the last kohler canister seal ring that came with the toilet originally. The toilet wasn’t even 4 years old & the ring (as shown in the pictures/red ring) was shot. So much so that the toilet wasn’t sealing so the toilet ran all night. This does replace the red seals. It seems better quality than the red ones too. I forgot to get a picture of the new yellow seal but it’s smooth & it is like others have said a little over 3 inches diameter (about 3 & a half inches diameter.) We have a class 5 & class 6 Kohler toilets( class 5 shown in pictures) & this Seal fits both (canister type flushers.) Super easy to install. Kohler has an instruction video on YouTube & I believe on Amazon, that helps guide you to replace the seal. I also bought the genuine Kohler toilet chain on Amazon(sold & shipped by Amazon) fantastic price & products are genuine.

I surfed the web to find out why my Kohler class five toilet would periodically run. The consensus was that this little yellow gasket was worn and needed to be replaced. There was a great Kohler video that explains the steps to make this little fix. I replaced the gasket using the steps and the toilet was STILL running periodically so I flushed it once and checked it a half hour later and realized it was still losing water in the tank. I turned off the water and flushed the tank to empty it. Then looked closely at the side that did not have the gasket and realized there were TINY pieces of plastic from the old gasket that needed to be cleaned off. Once that was done, I turned the water back on and checked it a half hour later and the water level had not decreased. So, that step is not mentioned in the video but it is important when you are replacing this yellow seal.

I purchased my home about 6 months ago and noticed the flush knob was ‘sticky’ on two of them. When I would press down on the lever, I’d need to use a bit of force. I didn’t think much of it until one day I noticed one of them running. I thought I was going to need to replace the entire tank mechanism, but a quick google search led me to these gaskets. I opted for this general Koehler part and am glad I did because it worked flawlessly. It fixed both the issue with the toilet running, and with it being ‘sticky’ to flush. Installation was super simple - the included directions were helpful but there are also plenty of YouTube tutorials if you need extra help. The improvement over the old gaskets was so nice that I went ahead and ordered a second to fix the other toilet before the old gasket on that one deteriorated even more. Others have mentioned (and is specifies on packaging) that your old gasket may be red - this yellow one is the right replacement.

My Kohler Cimmeron developed Phantom Flushing after a few years. Replacing this part fixed the problem. There were instruction on how to install on the back of the package, however I needed to watch a handy YouTube to complete the job. It was very easy and Im not at all handy.

This seal works well, easy installation,took me less than 20 minutes to replace. Saved a bundle repairing myself (no that handy) thought I would need a plumber.

product did what promised
