Perfect Replacement for a Kohler Cimarron w/ Red Seal

We have a Kohler Cimarron toilet that has the Red valve seal. This was a perfect fit replacement. Reason we got it was because after 2 years the toilet became very difficult to flush; you really had to put a lot of pressure on the flush handle - it was like it was stuck. Replacing this made all the difference - its back to new. A little tip here, the package comes with instructions on the back so when you come to the part where it shows to rotate the center disc portion of the canister mechanism counter clockwise to loosen, well when I did that it sounded like the plastic was going to snap at the shaft. So here's what you do, just lift the actual canister up enough to reach down below it and grab the center shaft at the base where it connects to the toilet tank. It will feel like a + sign in your hand - take that and turn it counter clockwise to loosen it, and then do the same (clockwise) to tighten it. It's a much sturdier way to take the canister mechanism off and on without feeling like you're going to snap the center shaft off.

This is the CORRECT seal for the RED SEAL REPLACEMENT

Looking for the replacement for that RED seal at the bottom of your Kohler canister? This is the one. I know its yellow, but this is the correct seal to stop the leaky/running Kohler toilet. SO easy to install. 1: Turn off the water at the base of the toilet 2: Flush the toilet (should be empty tank after flush) 3: Un-clip flush chain 4: Twist stem counter clockwise (twist hard till it clicks/pops) 5: Lift out unit from toilet tank 6: Replace red seal with yellow 7: Install in reverse (twisting the stem clockwise to tighten) 8: Re-install flush chain 9: Turn on water The seal package also has instructions that refresh all that i have said above. This is a do-it-yourself type project. I have uploaded pics of the old (red) and new (yellow) washer. Thanks

Worked great once the base this fits against was cleaned

I surfed the web to find out why my Kohler class five toilet would periodically run. The consensus was that this little yellow gasket was worn and needed to be replaced. There was a great Kohler video that explains the steps to make this little fix. I replaced the gasket using the steps and the toilet was STILL running periodically so I flushed it once and checked it a half hour later and realized it was still losing water in the tank. I turned off the water and flushed the tank to empty it. Then looked closely at the side that did not have the gasket and realized there were TINY pieces of plastic from the old gasket that needed to be cleaned off. Once that was done, I turned the water back on and checked it a half hour later and the water level had not decreased. So, that step is not mentioned in the video but it is important when you are replacing this yellow seal.

Works great

I have 4 Kohler cannister toilets in the house we recently purchased and 3 of them had issues—one was very hard to press the flush handle, one had a slow leak and would refill every half hour or so, one leaked nonstop and the water just started running until I shut off the water valve. I purchased 3 of these replacement gaskets which all fixed the different problems in every toilet. Highly recommend. I am going to buy another one to replace in the 4th toilet just to avert a problem likely to come. Highly recommend this part BEFORE you bother to replace the entire cannister gizmo. Glad I read the reviews and purchase the authentic part and didn’t do more than I needed to.

Works like a charm - installs in less steps

Installed mine on a Kohler toilet flush valve (see pic) - in less steps than listed in the instructions here or on youtube. Turn off the water + flush the toilet; grasp hold the canister and twist counter clockwise 1/4 turn till you feel/hear the click; pull it up slowly and install the seal - there IS enough space to maneuver and accomplish this without unclipping the chain or removing the water/refill tube. Then reverse the steps: fit and twist back the canister, turn on the water. That's it!

Fix your leaky Kohler and be happy

This product fixed my Kohler canister type toilet from leaking. The old seal was probably old when we moved into the coop in 2012. It started leaking only in the summers, then this year 2018, it was leaking all the time. I had gotten plumbers to come and look at both toilets that were leaking. They said they had to order parts, charged me $179 for nothing and they wouldn't come back. So I viewed the video on YouTube several times and got up the COURAGE to fix it myself (I'm 72). It took about 2 hours start to finish partly because I had to remove and reinstall a wooden over toilet cabinet. So after an hour it was done and works 100% better than before. Oh, I fixed the other American Standard toilet flapper as well.

Wow! A quick fix that made a world of difference!

After dealing with a slowly disintegrating gasket for months I finally purchased a replacement. The old one looked like it was made out of polar fleece. Apparently, the original natural rubber seal was damaged by the big clorox chlorine tabs I had put in the tank a while back. Replacing the gasket took almost five whole minutes from start to finish and now the occasional refilling on the toilet tank is gone and the physical effort to push down the flush handle went from a ridiculous number of pounds to a couple of ounces. This new seal appears to be made of a substantially more durable silicone rubber than the natural rubber of the original. The only complaint I have it that I should have replaced it a year earlier when I first noticed increased difficulty pushing down the flush handle and occasional sound of the tank refilling without reason. I bet it wasted thousands of gallons of water. Ugh! I'm planning on buying extras and taping them to the underside of the both toilet's lids so I don't have an excuse to delay replacing them the next time! If you have a toilet that uses this seal, it is a must-have upgrade even if you don't think you need it. Recommended without reservation.

Easy in, easy out.

Compared to the in-store $10 gasket for a pair, if there's any available, it's a few dollars less online for 1. Most in-store are the cheaper plastic versions that rotted away from the chemical exposure within a few years for the pair. Went through 2 of the red generic versions, due to the chlorine content reaching 3 to 5ppm in our water supply. From the reports for those who had gone before me, the new gasket formulation had so far sustain over 3 years of chemical exposure and abuses. Alrighty! Got me sold! Let's see how this gasket handles the high chlorinated content. The ring fits perfectly, eliminating any issue with water leakage. In and out in less than 5 minutes, with proper old rubber gasket removal and cleaning.

Very Easy to Change the Seal even if you are a Senior

My plumber charged me $120.00 dollars to change this same seal a couple of moths ago on one of my toilets. Another one of my Kohler toilets had the same problem 2 days ago. I watched a youtube video how to replace the seal on your Kohler Toilet canister. I ordered it 2 days ago on Amazon and received it today. Actually took me about 4 minutes to change out this new seal from the old red one. I didn't even take off the chain. It was very easy to do and I am a women of 66 years. Any ladies reading this review don't waste your money on a plumber like I foolishly did the 1st time. Replacing the red seal with this yellow one is very easy to do.

Kohler Branded Product

I received these toilet seals in Kohler retail packaging. I have 2 Wellworth toilets and both were leaking after over 5 years of service. Replacement was quick and the leaks into the bowls have stopped...what more could I ask for? Replacement was simple (Google if you need more help than the package offers), about 5 minutes per toilet. My biggest problem was that the water shut offs at the walls were corroded and needed to be replaced...that was a longer job and something to watch for as it is hard to change the toilet seal if the water does not shut off.
