Genuine Part Gp1059291 Canister Seal

For me, getting the chain off of the cylinder took a while. Gasket works. I took a leap of faith that this part would fit my Kohler toilet. Whew, it did.

On time good product

I have a Kohler Wellworth toilet with tank 4436 (tank numbers are stamped on the inside of the tank). I pulled up the parts list on the Kohler site and saw that this was the gasket required. My old gasket was red and severely degraded (although I didnt see how bad until I pulled it off and replaced with this yellow one). Toilet tank would slowly empty until the refill was triggered at random times during the day. Replacement was very easy, and I didnt remove the chain, you can access everything without doing that. Very easy repair and saved me a plumbers visit, my friend paid $139 for the same job. I appreciate all the comments left here in the reviews that explained so clearly how to do this.

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 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.

It was the perfect size to seal inside the toilet tank. It was the size recommended by the toilet manufacturer. I have no idea how it was installed or what was done. It was installed very quickly and the toilet stopped constantly running.

I put off changing the gasket for awhile and I wish I hadn’t. It couldn’t have been easier. I watched a short video on how to remove the canister and it came right out. The whole process took less than 5 minutes

The hardest part of this was figuring out which one to order. Once I figured that out & this arrived it took me less than 10 minutes to remove the worn out seal, replace it with this & have the water to the toilet back on & flushing. Wooohooo. I was cursing Kohler when trying to identify which seal needed to buy - now that I know that & how well designed the system is for easy seal replacements I am back in love with Kohler products.

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.

The installation of this replacement seal was easy, but unhooking the valve cylinder in order to install it was the real pain. It stays in place, and the toilet no longer runs, so yeah, it does what it says on the blister pack.
