Genuine Part Gp1059291 Canister Seal

product did what promised

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.

Our home was built in 2013 and the builder put in Kohler products throughout the house. Fast forward to 2021 and some toilet flush mechanisms were getting harder to flush and it turns out that these gaskets need to be replaced to maintain a tight and smooth seal between the tank drain and filll cylinder, especially if you have hard water or big changes in temperature. In our case, the hard water basically dissolved the original gaskets and it was sticking to the tank drain hole when flushing. The new one is super easy to install taking only 2 to 4 minutes. After the install, the flush mechanism is super smooth and water seal is tight. Stick with original Kohler parts for exact measure and perfect fit.

My in-suite toilet would every so often sound like it a was automatically flushing itself all through the freakin’ night! It kept me awake! I thought it was the flush mechanism so I changed that! Then I observed that it was this O- ring that needed to be replaced! This item is the original Kohler replacement. Don’t buy the fake ones, you’ll just waste your money. These aren’t so expensive anyways. Save yourself the headache and get this original replacement! Getting my well deserved zzzzs!!!

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.

Very easy to install. Fixed the problem of my toilet running.

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

Easy to install.

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.

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.
