Review on 5-Pack of Kohler-Compatible Canister Flush Valve Seal Replacements (Equivalent to K-GP1059291) - Ideal Replacement Parts for GP1049291 Tank Canister Gasket Kit - By IMPRESA by Michael Miner

Bought a pack of 5 in March 2018 to replace the OEM gaskets in two Kohler toilets installed in October 2016 became. We immediately noticed that they were gaskets of different diameters and widths (see attached photos) but decided to try them anyway. The first seals installed in March 2018 began to leak after just a few months. I installed another set of 5 packs and they only lasted until October 2018. Now I have replaced 2 sets with gaskets from another manufacturer, I hope they work better. I wouldn't buy them again.
