PlumbCraft Flush Valve Seal Replacement, Fits KOHLER Class Five and Class Six Canister Flush Valves

The original seal I had with the installation kit went bad within a year or so and practically fell apart. I replaced it with one of these. The same type of leaks started happening again after about the same amount of time so I ordered some more seals a few days ago. As I went to remove the one off the toilet today, I noticed it seemed to be very solid still so I ran my finger around the bottom and found there was a build up of gunk that just needed to be removed. Now it works fine again. I didn't want to check like last time because that one just fell apart with minimal touching it so it is good to know this one does hold up well. I would recommend this item since it likely will last 5+ years based on the pliability of the rubber still today. Looks like I have the extra one of these I cannot find and 4 more seals. I guess I will be good on seals until 2044. Haha.

This flush valve seal fits the Kohler system well. My old one lasted just about five years of use. Coincidentally, the warranty is five years. Replacing the old one was an easy job as handy jobs go - just take out, wipe excess debris and install new one (no tools needed, just your hand). I bought one and purchased two more just in case for posterity.

I was ready to go the hardware store with part numbers and going to buy a whole new kit, but looked if I could find this by the part number. In 5 minutes I replaced the seal and everything works fine again. Sure beats calling a plumber or buying a kit for 15 to twenty-some dollars and going through the hassle of replacing parts that are not broken.

When we moved into our house in 2011 we replaced all the toilets with new lo-flush Kohlers. Now, as if on cue all of them had developed leaks around the seals in the flush canister, making the toilet turn off & on by itself erractically. Sometimes waking us up in the middle of the night. Wasteful and noisy. Really annoying. These seals fixed it. Fits perfectly in our 3 Kohler lo-flush canister plumbed toilets. I installed the new seals (no tools needed) in all 3 toilets in less than 6 mins.

Ok it has a 5 year warranty, but who is going to waste their time chasing a few bucks. Fit was fine and installed easily. Worked great for 20 months and then developed a bulge that wouldn’t make the seal. I’ve installed the second one so maybe it will last a little longer. I think I expected it to last longer.

I checked out the dimensions and measurements for this gasket that were included in the description and measured my existing gasket which was worn out, the measurements were a match. Re-installed the old gasket and waited a day for the new one to arrive. Once the new one arrived I applied a very light film of plumbers grease and installed it. Worked perfectly, great product at half the price of the local HW store.

I went with this ove rthe original Kohler made valve. Unfortunately, this didn't do the trick and the toilet still runs. I think its due to a faulty construction which left an uneven surface on the unit I received. The bumpy surface allowed passage of air and thus a running toilet. Going with an original Kohler instead.

I don't know why I waited so long. This solved a persistent leak (toilet refilling a lot), and took 2 minutes to install. Just detect the little chain, remove the old, slide this new one down, and fit it into the groves below the plastic valve.

This part works perfectly which is great. What I dislike (puzzled is probably a better description and this cost one star) is the fact that there seems another qualified option from Kohler itself that costs less. Does anyone have any clue?

it was broken i googled the repair , i looked for part on amazon, it was perfect fit, fixed my toilet and done :) !!

Fit perfectly, no more leaks

Would use this again.

Easy to install with clear instructions. Well priced
