Genuine Part Gp1059291 Canister Seal

After dealing with a slowly disintegrating gasket for months I finally purchased a replacement. The old one looked like it was made out of polar fleece. Apparently, the original natural rubber seal was damaged by the big clorox chlorine tabs I had put in the tank a while back. Replacing the gasket took almost five whole minutes from start to finish and now the occasional refilling on the toilet tank is gone and the physical effort to push down the flush handle went from a ridiculous number of pounds to a couple of ounces. This new seal appears to be made of a substantially more durable silicone rubber than the natural rubber of the original. The only complaint I have it that I should have replaced it a year earlier when I first noticed increased difficulty pushing down the flush handle and occasional sound of the tank refilling without reason. I bet it wasted thousands of gallons of water. Ugh! Im planning on buying extras and taping them to the underside of the both toilets lids so I dont have an excuse to delay replacing them the next time! If you have a toilet that uses this seal, it is a must-have upgrade even if you dont think you need it. Recommended without reservation.

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.

Not as easy to replace as a standard flapper, but easy enough. Genuine part works exactly like the original and fit perfect. I appreciate that they did not gouge the price too much, although Im sure the production price is like 10 cents. Appreciate the next day shipping when the toilet is not working, needless to say.

It was the perfect size to seal inside the toilet tank. It was the size recommended by the toilet manufacturer. I have no idea how it was installed or what was done. It was installed very quickly and the toilet stopped constantly running.

Took a chance and tried to go cheap - bought a two-pack of aftermarket (non-Kohler) seals that sold for the same price as one Kohler. Wasted my time and money. Both leaked from the start. After taking a wire brush to all contact surfaces to ensure old seal left no remnants. Flipped each to see if I could seal - no dice. Kohler seal came a few days after order. Not a drop leaks anymore. Dont waste time and try to skimp. Go straight to Kohler. Do not pass go. Do not collect $200.

Easy to install

original equipment works ok

I had a condition that my wife researched and found to be called phantom flush. The toilet was slowly leaking and having to refill itself every few minutes. I investigated and found that if I moved the seal around a little on the canister valve, it would stop... but only until someone flushed again. In the end, I realized that the original seal seemed a little stretched out, so I ordered this one. I went with OEM after reading some so-so reviews on the aftermarket seals. This was a little bit costlier, but three months of not having to hear the toilet randomly refilling itself all through the night makes it totally worth it. If this one fails over time, I will absolutely buy it again.

been working good. No problems.

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.
