Genuine Part Gp1059291 Canister Seal

My toilet was leaking and when I opened the top to change the flapper (as I usually do on my other toilets) I realized that this toilet was different. I, of course started looking for options of changing the innards and ordered the complete cannister from Amazon (of course) I had it the next day and it looked just the one inside my toilet. But while looking up videos on how to change it I stumbled on a video of how to change the seal. The seal was only a third the cost of the cannister, so I ordered it, and it arrived quickly. I changed this out in about 5 minutes and it works perfectly. Not sure how long it will last, but for now its perfect!

Overhauled my toilet due to hissing during refill. Since I was replacing my fill valve figured the canister could use a new seal too. Replacing the seal took about 5 minutes after watching the Kohlers video. Hardest part for me was disconnecting the chain which wasnt cooperating lol. I cleaned the old seal residue from the canister and where it seats to and installed the new seal, now its good as new.

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!

I have a couple Kohler Cimarron and one Kohler Wellworth toilets that use these seals. On the Kohler site, theyre shown as yellow, but this image shows a red seal (like the original). The seals I received were yellow, which allows the user to more easily see that theyre installed evenly and correctly. Ill post a picture of the actual seal later. [...] The instructions on the back of the packaging were super-easy to follow. Its a simple matter of a quarter-turn to unlock the cylinder, then lifting out the cylinder and replacing the seal at the bottom. The seal went on easily and my toilet was fixed in about a minute or two. Nobody should feel intimidated by this process! Anybody can do it. The only issue I had was that the plastic piece that locks the cylinder down seemed to be stuck a bit, so I was afraid I would break it, but it broke loose and came off easily after that. It was a simple quarter-turn to remove it. I bought a couple of these. Shipping was covered by Amazon Prime, whereas on the Kohler site there was a shipping charge. Excellent product with simple instructions on the back. Highly recommended! I now really like this better than the old style flapper seal. Dont pay anybody to do this for you! You can do it!

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.

After disconnecting the water line in tank, I had a little trouble twisting the yellow cap off -- was afraid it would break b4 it turned. But the gasket fit in the groove perfectly. But the tank still leaks -- green food coloring doesnt lie. DK if its another tank part or the valve at the wall. So, will call in a plumber after all. At least I know what the problem isnt.

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.

I purchased this to fix a toilet that was periodically refilling throughout the day due to an insecure seal under the flush canister. Im not much of a handyman, but I took a chance on this since it was only about $5, much cheaper than calling a plumber. It turned out to be an easy fix, and the toilet has not been losing water since installing the new canister seal about a month ago.

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.
