Rated 4.3 out of 5 by 34 reviewers.
Rated 3.0 out of 5.0 by I wish there were 2 Kohler and no AS This valve seal fits the Kohler flush valves with the big black plastic valve. It also includes a seal for an American Standard flush vale that is very similar. I would much rather see 5 Kohler valve seals in a package. I never use the AS seals, but I can't throw them out either. July 7, 2015
Rated 3.0 out of 5.0 by Works we;; but costly I cannot recommend this product vs the alternative if your water closet has this system change it out that is my plan for next time. June 30, 2015
Rated 5.0 out of 5.0 by Perfect Installed easily and sealed perfectly. What more can you want! February 10, 2015
Rated 5.0 out of 5.0 by Good Product lousy install instructions Great Product. Do Not follow the package instructions for installation. They will get you into serious trouble. Access the seal by removing the canister from the bottom NOT the top. November 12, 2014
Rated 1.0 out of 5.0 by Didn't work used on my Kohler toilet and leaked worse than the valve i was replacing. spend the extra $1.25 for the Kohler brand replacement. April 7, 2015
Rated 5.0 out of 5.0 by Perfect fit I have a 5 year old Kohler Cimarron that called for #1016219 (replaced by 1097686 according to the Kohler web site). I couldn't find the OEM part locally, so thought I'd try this. I installed it two weeks ago, and it's working perfectly. It took me about two minutes to replace, thanks to the YouTube video explaining how to remove/reinstall the canister: How To Replace The Seal On A Canister Style Flush Valve from Kohler. July 13, 2013
Rated 3.0 out of 5.0 by Please package separately I've bought about 5-6 of these just for the ring that fits the Kohler and threw the other away. There wasn't a "Kohler only" pack available. It seems a waste of money and material to only offer it this way. March 10, 2015
Rated 4.0 out of 5.0 by Korky's great customer service Have purchased this a few times, didn't last 5 years. Contacted the company, Lavelle and received a quick response. They held their warranty claim & sent me a free replacement immediately . Great customer service, so refreshing today! Would recommend them over & over! USA company too! Thanks Lavelle, July 2, 2014
