Genuine Part Gp1059291 Canister Seal

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.

Had a Kohler toilet that was getting increasingly hard to flush. It was obvious the flapper was sticking somehow, but when I opened the tank I was baffled by the weird design. I went to YouTube and found a video that showed how to twist the center stalk of the “flapper” and remove the long tube. Sure enough the old red seal valve/ring was falling apart and gummy like an old rubber band. Had to run a pocket knife around both sides to remove the crusty bits and then the new yellow gasket just gets stretched on. 2 minutes on YouTube, 5 mins removing the old gasket, and 30 seconds to install the new one.

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!

Easy to install! Solved our issue with toilet refilling ALL the time! The old one was definitely worn and had bubbles. Lots of youtube tutorials on how to change this out. If your kohler toilet is running refilling a lot give this a shot before replacing!

This seal works well, easy installation,took me less than 20 minutes to replace. Saved a bundle repairing myself (no that handy) thought I would need a plumber.

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.

Easier to install than the whole can assembly. If all of your plastics are still in good shape, but the flusher sticks or the water is always running, the this is the easiest fix.

Easy to install

I moved to a new place and the toilet was shut off as it was leaking water. I had not seen the toilet yet and thought it was a normal one so I bought a repair kit and found the toilet was very different from any I had seen before. It did not have a standard flapper so the repair kit would not work. I looked up the brand and model number and found out it used a ring gasket to seal the cylinder. I could not find one in town as all that was available were standard flappers. I found the right gasket here and it installed without a problem after watching a YouTube video on how to remove the cylinder. The old gasket was gooey and sticky but came off and cleaned up without much difficulty. The new seal is working so far with no more running water.
