Genuine Part Gp1059291 Canister Seal

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.

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’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.

This seal took five minutes to install, and it fixed my constantly running toilette problem. A new Kohler fixture that in less than a year developed the running water problem. Now its one of the new efficiency models, so I could not run out and drop a conventional Fluidmaster replacement in. I asked my plumber( as he was replacing the old cast iron under my kitchen sink) about it; sounds like a bad seal to me his reply. I matched that with the diagram on the web and concluded it was worth a shot. But, Im not going to run all over town looking for a seal that only fits a specific make and model. Amazon has never let me down,so type the part number from the Kohler manual in the search box and bam; six bucks at my door in two days (Prime Member). Next one click. Installed it in five minutes and my water headache was gone. For the dollars involved one of the best purchases I have ever made. My praise is not for Kohler but for Amazon in saving me gas,time and the fear of having to pay a plumber for something that in the older models was a easy fix.

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!!!

In a time where the news can make us feel scared and confused, it’s good to know that there are gaskets like this that still exist in this world. When my wife first informed me that our toilet was running, I experienced a personal moment of pure elation. “Please let me have to replace the canister gasket” I silently muttered over and over to myself as I dipped my bare hands into the mechanical bowels of the place where one does such things. Upon dismantling of my toilet hardware and watching you tube videos over and over again in self imposed perpetual foreshadowing, it was finally time to crack open my most awaited package. After consuming what was in my most awaited package, now being fully nourished, I was ready to tackle the gasket. ITS GASKET TIME, BABY!!!! Let me say, first of all, that in my almost 40 years on this earth, never have I seen a gasket quite of this caliber. From its durable rubber feel, to its bright mustard hue, there was nothing about this gasket that wasn’t magnificent. As I reached in to remove the sad faded reddish pink gasket from the canister, I was struck by just how amazing the new gasket was. It was just so gasketty. I apologize in advacne for any typos but my eeys are blurred with the tears of memory... I trembled with anticipation as I attempted to un-disassemble my toilet tank in the reverse order from earlier. Now, let me assure you that NONE of the following is the fault of the “Golden Gasket”. In fact, when discussing the situation with my plumber afterwards, he reassured me that this gasket was indeed the finest he too had ever seen, was in perfect working order, and was in no way responsible for me snapping off an essential part of the inner toilet tank that prevented it from properly filling. It’s about 62/38 as to whether he meant what he said or was just agreeing with me because he thought I was a bit crazy, but that’s not important. The important thing is “GASKET”. Just that. I imagine that, by reading this review, you too are as fanatical about gaskets as I am. I mean, why else would you possibly be reading a review of a replacement product for a toilet tank? Exactly!! Gaskets. In conclusion, this yellow ring did its job and now I don’t have to hear anyone complain about the toilet running. Yay gaskets...

This was a perfect replacement. Don’t gamble and buy one of the off-brand replacements. Save your time and money and buy OEM.

On time good product

original equipment works ok

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.
