Kohler 1131496 Flush Canister Seal, 2.5 x 2.5 x 0.1 inches

Update Jun 2024: So the seal lasted some 7 years. I thought I heard cycling in middle of the night, looked the next day, and there were three "bb's" on it. An extra 7 yr old replacement was installed and is working fine. Update Sep 2022: The 2018 seal is still working fine. I've been careful not to put cleaners into the tank. Update Nov 2020: So, 2 1/2 yrs later, the seal I bought in 2018 still is working well. I'm glad folks found below helpful. This seal worked to stop what I call cycling (others call it ghosting) on my 4 yr old Kohler dual flush toilet -- where some water silently leaks out of the tank and, after a few minutes, the tank refills to full. If your tank has a white canister in the middle, with tabs at the bottom allowing you to vertically pull it out (vs the canister model which twists out), this seal is a great candidate as a fix. And as others have mentioned below, my old seal had several hard bumps, each the size of 1/4 to 3 BB's -- I'm sure one or more sitting on the plastic pipe fitting were the source of the leak. The main thing I want to add is that the Kohler web site has tools to determine the model toilet and then spec sheets with exploded parts diagrams of the tank workings. Look at the toilet spec sheets closely -- you may see different part nos for the tank and bowl on the sheet. If you can't get to the diagram of the parts, try googling your tank model number and looking for the diagram via the tank data sheet (not easy to get to except via google). And, all else failing, Kohler's customer service is very helpful/responsive. Note also that some tanks allow for upgrade to the newer twist-on canister (a $65 part), but the upgrade requires removal of the tank. Before paying for the whole, updated canister service set and hassle of installing it ... if you have the old style with removal tabs ... definitely first try replacement of just this 1131496 seal. (The newer canister has a different seal at a different location.) All of above will be clearer if you pull the diagram(s) from the Kohler site. Above said, if you do have the pop out canister, it's very easy to use the two tabs to pull it out -- then pull off the old seal, stretch on the new, and to pop the canister back in.

Quick and inexpensive fix for leaking toilets. Installation takes less than 2 minutes. This is always the first thing I try when I hear a toilet in my house occasionally filling when not in use. Only once out of about 10 times it did not resolve the issue. But for the cost and speed of installation it is always worth trying first.

Perfect fit and an easy diy to fix a running toilet.

The fancy flush valve in our Kohler toilet suffered when I added a cleaning "tablet" to the toilet tank. There's a not in the tank that warns against using the tablets but I'm smarter than that. Until the silicone developed bubbles similar to what others report. The original lasted almost three years with my abuse. I bought the replacement and a couple spares, so I can keep using the tablets. Installation was a snap. Turn off the water supply and flush the tank level down. The flush valve releases so it will turn and can be removed. Slide the old disk out, slide the new disk in, put the flush valve back in place with a slight twist until it snaps into place. Turn the water back on. No leaks. Cover goes on the tank. Shouled be good for another couple years.

Worked perfectly on a Caroma two-piece Caravelle toilet. Apparently that is now the "old style." Our two-piece Caravelle is between ten and fifteen years old. It seems these gaskets last about a year, maybe two. The new gasket was translucent, almost clear. The old gasket was milky, a bit mottled, had some rough specs adhered on the surface, and felt waterlogged. Time for replacement. Twisting out the center column in the tank took five seconds. The twist is less than a quarter turn, maybe just one eighth (right hand thread, counterclockwise). Changing out the gaskets took ten seconds. Then twist the center column back in (clockwise). Frankly it took longer for the tank to refill than it took to replace the gasket. Success. Tank is holding water properly. This Kohler replacement part worked perfectly in my Caroma toilet. I also want tho thank those who responded to my question on this gasket. I asked if this Kohler gasket would work in the Caroma toilet. Several responded, saying it would work. It was a good example of the community as a whole being smarter than any one of us. Much appreciated.

Please note that this seal will NOT work with the Glacier Bay dual flush toilet as one other reviewer has pointed out. I wasted a good week only found out the part didn't fit. This Kohler seal is way too small for the Glacier Bay toilet. By the way, you can actually call Glacier Bay for replacement part (this is a Home Depot brand). Not sure if they have life time warranty but they had no problem shipping a couple of replacement seals to me for free.

Toilet no leaky no more!

Works ok

This item fit and worked great on the toilet stopped water from leaking perfect tight seal . 2 thumbs up

just what i need to stop a toilet tank from losing water. Install was very easy, the hard part for me was diagnosing the issue myself, but took a chance by ordering this relatively cheap part.

I actually tried several local stores for items that would fit and none of the universal ones were the right size, so this one as a Kohler part was a perfect fit, could have saved myself multiple store visits and returns by just looking here first.

Just what I needed.

Finally I get a full flush! I was wasting so much water and this simple repair stopped the trickle!
