Genuine Part Gp1059291 Canister Seal

Easy to install

We had a bathroom renovation two years ago and the new toilet had a canister flush valve. I heard the sign of a flapper valve leak, spontaneously refilling, and discovered the canister in its place. I watched a clip on YouTube that explained simple maintenance of the canister. I ordered this part and when it arrived it took just a few minutes to replace the o-ring. When I turned the water on, the spontaneous leak was gone.

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 little gasked is a $7 miracle. My toilet started running and after a few weeks, no matter how much handle jiggling I did, it was clear that I needed to make a repair. The water was running as often as not. Looking into the tank I saw the old pink gasket and MAN was it in bad shape. Probably the chemicals in the water did it in, as its a relatively new toilet. This new gasket arrived and I was able to get the old one off/put the new one on in less than 5 minutes. The hardest part was disconnecting the chain (what a pain!!). Once I got past that step, the rest was simple. I do highly recommend that if your old gasket was in rough shape, that you take a moment before putting the new one on to scrub away any residue that might be left over. There was quite a bit on mine, but nothing a scrubber sponge didnt quickly handle. Happy Flushing!

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.

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.

I wanted to have an extra gasket for my toilet.

Fit like a charm

Our home was built in 2013 and the builder put in Kohler products throughout the house. Fast forward to 2021 and some toilet flush mechanisms were getting harder to flush and it turns out that these gaskets need to be replaced to maintain a tight and smooth seal between the tank drain and filll cylinder, especially if you have hard water or big changes in temperature. In our case, the hard water basically dissolved the original gaskets and it was sticking to the tank drain hole when flushing. The new one is super easy to install taking only 2 to 4 minutes. After the install, the flush mechanism is super smooth and water seal is tight. Stick with original Kohler parts for exact measure and perfect fit.

The toilet valve was going on for about 30 seconds every half hour all day and night. I’d get up an hear the toilet running, then it would stop. Read about replacing this seal, a 10 minute job, and now the toilet works like it should. I noticed that the old seal had developed a small bubble which allowed a tiny amount of water to leak, eventually triggering the valve to fill the tank. This seal fixed the problem...no plumber needed!
