Genuine Part Gp1059291 Canister Seal

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

This was a genuine Kohler replacement part that I received (packaged in Kohler packaging). I am not a handy person AT ALL and even I was able to get this new seal installed on my Kohler toilet to prevent it from running. Kohler has some how to videos and manuals online. the estimated time to switch said 5 minutes, so i anticipated it taking 20 (thats how bad I am), but instead, I did it in less than 5. Glad I tried this myself and didnt call a plumber, I would have felt foolish.

This part was just what I needed to fix a toilet tanks that was not filling up when flushed. I replaced the old red rubber seal with this one and it worked like a charm.

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

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.

Easy to install

Fit like a charm

The ring gasket it replaced was allowing a significant leak in my toilet tank despite no apparent damage. This causing my water softener to go through regeneration cycles approximately 3 times as often. I installed the new ring gasket and no more water leakage. Saving $20/month in softener salt.

First, I bought a cheap 3rd-party seal that was supposed to be compatible, but it leaked because the diameter was actually wrong. Then I bought this official Kohler seal, and it works great.

Had a Kohler toilet that had a leak due to bad o ring. I looked up the part and this was it. I installed it in about 1 min. Problem solved. Very satisfied.
