Save water and stop a running toilet with the Fluidmaster 502 PerforMAX® Water-Saving Flapper.
The 502 flapper is the gold standard of flappers. Not only is it our longest lasting flapper, but it also comes packed with features that ensure you’re getting the best flush every time.
The PerforMAX® flapper is chlorine and hard water resistant and features a solid frame that doesn’t twist for the best seal every time.
