Older 3.5-gallon Kohler toilets use a specific flush valve, and this 2" flapper is matched to seal it and restore a full, clean flush to those higher-volume tanks. It seats on the valve to hold the tank water between flushes and lifts to release the full charge, so replacing a hardened or warped original stops the seepage that makes the toilet run. Because it is sized to the Kohler valve, it seats correctly without the leaks a mismatched universal flapper can leave. For maintaining older high-volume Kohler fixtures, it is the correct-fit repair part.
