Description
The Fluidmaster® Universal 2” & 3” Super Flapper is the newest and most universal toilet flapper in our flapper line. The Super Flapper is the go to choice, taking the guessing out of what size flapper is needed in the tank. When you don’t know what size flapper you need this fits both 2” & 3” toilets. This can be converted into a 2” flapper or 3” flapper – the ONLY one of its kind on the market. This Super Flapper sets the standard as the easiest installation possible for a flapper. Depending on your flush needs the water adjustment feature with the easy-to-turn adjustment dial allows for the customization of water usage inside the tank. This universal design is built to adjust and work with most toilets and brands using two-piece toilets and flush valves.
