504 Sure-fit Super Flapper, Red, 2 Inch

The Fluidmaster 504 Sure-Fit Super Flapper is a universal replacement flapper designed to restore proper flushing in toilets. This flexible, one-piece flapper fits most 2-inch brass or plastic flush valves found in toilets with 3.5 gallons per flush or larger, whether or not the valve has mounting ears. Replacing a worn flapper helps restore toilet efficiency and reduce water waste.

The 504 is engineered to withstand harsh water conditions, including chlorine and mineral buildup that can break down lesser flappers over time. It features built-in Microban protection—not just a surface coating, but protection integrated into the flapper's construction—to prevent bacterial growth and material degradation. Installation is quick and straightforward, and the product includes a strong, kink-free metal chain and an adapter ring for overflow pipes without mounting ears, making it compatible with most toilet designs, including American Standard actuator units.
