Genuine Part Gp1059291 Canister Seal

Hard to rate just yet, as I need to see how well/long it holds up when continually immersed in a chlorine based tank sanitizing tablet. Kohler says not to use tank chemicals as they void the warranty, but the tablets have been a necessary evil for me to eliminate biological build up of rings in the bowl. The OEM seals were orange-red and had deteriorated within about 3 years. They got sticky and made using the flush handle very stiff as the seal was bonding with the plastic cylinder [part of the float system]. Not sure if they began to fail because of the chlorine or some material defect. However, it appears that Kohler has this new replacement seal which may be a different material and may withstand the chemicals better. In any case, the seal was a perfect fit and simple to install although the instructions were not useful. There is a trick to removing and re-installing the 6 solid plastic center shaft so that it is easily removed/re-installed. The trick being to rotate the shaft to unlock/relock it in its base, which is hidden from easy view. You may want to check out u-tube videos on the process if you are not familiar with this Kohler design.

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!

Easy to install

Took 30 seconds to replace. Easy and perfect . No leak down just like new.

Works perfectly and looks great !

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

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.

This part is a perfect OEM replacement. Simple and easy DIY replacement

Do it yourself and save a ton of money. It fixed the leak in minutes.

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.
