Stop a running toilet with the Fluidmaster 500 Universal Toilet Flapper.

Unlike flexible flappers, the 500 flapper features a solid frame that doesn’t twist for the best seal every time – so you never have to worry about jiggling the toilet handle again! The 500 Universal Flapper is best suited for use with 3.5+ gallons per flush toilets.

Only Fluidmaster has toilet flappers with built-in Microban® protection. Not just simply a coating, Microban® is specially built into the construction of our flappers to fight flapper breakdown and combat bacteria.

  • Fits most 2” flush valves
  • Solid frame for the best seal every time – no twisting
  • Built-in Microban®
