Rated 5 out of 5 by You need this! If you already have one of the 400 series valves installed you want a few of these on hand. It seems like every three years or so the valves start leaking from use and chlorine in the city water. In the past, I would go get a whole new valve for $12-14 and spend a half hour or so laying under the toilet replacing everything then dealing with the obligatory spot leaks. This seal is normally the culprit and can be replaced in just a minute with no tools and its right at the top of the tank. I keep a full 400 kit on hand with the flapper [the other part that gets hard from the chlorine] but most of the time its this seal. Pop a new one in and DONE! Then I pick up another spare on my next run to the store for next time. March 4, 2014
Rated 5 out of 5 by Easy 30-second Fix If you're having issues with your tank refilling after flushing then this is probably the part you need. Both of my fill valves went bad about a month apart, roughly 2-3 years after I installed each of them. It's a shame the part wears out so quickly, but at least it's a cheap and easy repair.

Rated 5 out of 5 by Worked for me!!!! This was much easier and cheaper then replacing the whole valve. Note: My previous seal was not visibly defective. April 26, 2014
