Product Details

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.

Key Features:
  • Fits Kohler 3.5-Gallon Valves -- Matched to the flush valve in older high-volume Kohler toilets for a correct seat.
  • 2" Flapper Seal -- Seats on the valve to hold tank water and stop between-flush seepage.
  • Restores Full Flush -- Renews the complete flush a 3.5-gallon tank is designed to deliver.
  • Cures a Running Toilet -- Replaces a hardened or warped original to end the refill cycle.
  • Correct-Fit Repair -- Sized to the Kohler valve for a reliable seal without universal-flapper leaks.
Where to Use:
  • Building maintenance -- Repairing running and leaking toilets across a property's restrooms.
  • Unit turnovers -- Restoring quiet, sealed toilet operation during apartment prep.
  • Plumbing repair -- Stocking a fast-moving tank repair part for first-visit toilet service.
