Sized for 3" flush valves, this blue Gerber flapper seals the larger flush opening found on many modern high-efficiency and commercial toilets, where a standard 2" flapper simply will not fit or seal. It seats on the 3" valve to hold tank water and lifts to deliver the fast, full flush a 3" valve is designed for, and replacing a worn one restores that performance while stopping leaks. Matched to Gerber 3" flush valves, it seats correctly for a reliable seal. For running or weak-flushing toilets built around a 3" valve, it is the correct-size repair part.
