3010BP Toilet Flapper, 3-1/4 In., Red Rubber, Fits Kohler Cimarron

The Korky 3010BP is a replacement toilet flapper designed specifically for Kohler Cimarron toilets and other Kohler models with oversized flush valves manufactured after 2004. This larger 3-1/4 inch flapper provides an expanded sealing surface to stop leaks and reduce water loss.

Made from premium red chlorazone rubber, this flapper resists chlorine, bacteria, city water treatment chemicals, hard water, and well water—extending its lifespan even in challenging water conditions. The flexible rubber material conforms to the flush valve for a reliable, tight seal. The universal design allows quick replacement without professional help.
