Flush Valve Seal for Kohler, 3 Pack Upgraded Silicone Toilet Replacement Tank Parts for K-GP1059291 Canister Flush Valve Kit Gasket

The Kohler original flush valve seal began leaking after 7 years. Bought these "New & Improved" replacements & installed one & taped the package of the other two inside the bathroom vanity. Leaks stopped. If truly improved, I'll use the second of three seals in about the year 2030.

This fit perfectly. You can’t put regular flapper on other toilet their toilets are different and this fits.

Works great. Very easy to install.

worked well and seems to last longer than the red seals due to better material

Ordered because I had two toilets that were leaking. Easy to install. One toilet is fixed the other still continues to leak. Will be using the last gasket to see if I can try that one again. I wanted original Kohler parts; but I can't be sure that is what I received or if they are a knockoff brand since they are just in a plastic with no writing on the bag. Anyway; let's hope the last one is the answer to my leaking toilet.

Great quality and price

The seal developed a blister/bubble after four months. Developed bad leak

Stopped that. Quick refill every hour

When I first opened them they looked a tad small, but they work perfectly. Perhaps my old one stopped working because it got stretched and sloppy. So don’t be surprised if it looks a little smaller. Just snap it in securely and it works.

We had several toilets start leaking over a few months, thought the mechanisms were wearing out. After discovering that the seals were actually falling apart, I ordered these from Amazon. Took only a couple minutes to install each one, once I had done the first one of 5. The old OEM gaskets had frayed and disintegrated in various amounts, so removing the remains of each from both plastic pieces actually took most of the time. Putting on these new seals was real simple! Not only that, but we will be using much less water now that the old leaking seals are gone! The toilets are 8 years old, so I learned to consider replacing the seals after maybe 5-6 years instead, with inspections done accordingly. The packages arrived next day, so no complaints there either!

It's a seal , what's to say...

Good quality product

Genuine Koehler gaskets have a smooth surface, these gaskets have tiny ribs, see pictures.This causes the toilet to randomly refill.After changing to a genuine Koehler gasket, everything is fine.Genuine Koehler gaskets are overpriced, but they work.
