Genuine Part Gp1059291 Canister Seal

My daughter and I were able to easily replace the gasket on my Koehler toilet. I ended up paying a little more for a genuine Koehler gasket and there was a You-Tube explaining how to do the replacement. Very straightforward!

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.

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.

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.

UPDATE—exactly 4 years after I purchased these, they started to fail, water was draining out of the tank and I would hear the toilets periodically refill, which progressively happened more and more frequently. When I removed these to replace them again, I noticed that they had stretched out and were considerably more loose than a brand new replacement. So I am concluding that these have a four year life. ORIGINAL REVIEW: have 4 Kohler cannister toilets in the house we recently purchased and 3 of them had issues—one was very hard to press the flush handle, one had a slow leak into the tank and would refill every half hour or so, one leaked into the tank nonstop and the water just started running until I shut off the water valve. I purchased 3 of these replacement gaskets which all fixed the different problems in every toilet. Highly recommend. I am going to buy another one to replace in the 4th toilet just to avert a problem likely to come. Highly recommend this part BEFORE you bother to replace the entire cannister gizmo. Glad I read the reviews and purchase the authentic part and didn’t do more than I needed to.

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.

If you have a leaky/running off and on Kohler toilet, this part replaces the red ring that is on the bottom of the black tube in the toilet tank. The original red ring came apart easily over the years, and this replaces it. Check out the toilet lid underside for parts options, and if you cant determine it, call Kohler and ask what they recommend, with the part number required. To install this part: switch off water below tank, flush the toilet to drain the water in the tank, open the lid, remove black tube (squeeze widthwise), and scrape off red ring that has eroded. then replace it with this ring. replace lid, and turn on water, and flush! 5 minutes to replace, countless gallons of water saved

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!!!

Works like a charm!

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!
