Score: 72/100Rankings

The Korky 3060BP is a universal 3-inch toilet flapper designed for high-efficiency toilets, featuring durable red rubber resistant to harsh water conditions. Its main trade-off is the need for manual adjustment of the vent band to match OEM water levels. It is best suited for owners of post-2005 HET toilets with 3-inch flush valves.

The iFealClear 3-inch Toilet Flapper is a high-efficiency, water-saving rubber replacement part designed specifically for Gerber 99-788 flush valves in high-efficiency toilets. It features a 3-inch diameter with a single large hole in the cone, blue coloring for visibility, and an adjustable chain with dot markers for easy installation without tools. Ideal for DIY residential bathroom repairs, water conservation upgrades, and quick replacements requiring an exact OEM fit.
