The Fluidmaster 501 Universal Chlorine-Resistant Toilet Flapper is designed to be a longer lasting and high quality flapper replacement, to fit most 2” flush valves. Built tough to last in any water condition, with chlorine-resistant materials and built-in Microban. Only Fluidmaster has toilet flappers with built-in Microban protection. Not just simply a coating, Microban is specifically built into the construction of our flappers to fight flapper breakdown and combat bacteria. The solid frame ensures a secure seal, by resisting bending, or twisting during flushing, so you never have to jiggle the toilet handle again.
