Kohler 2-Inch Hardbody Toilet Flapper – Premium Replacement Part

Fix Your Flapper Problem – Permanently.

This 2‑inch hardbody toilet flapper is designed to deliver consistent, high‑efficiency flushing performance across a wide range of standard toilet models. Its angled profile positions the flapper closer to the tank floor, allowing greater water displacement at the start of the flush cycle. The extended‑open design ensures the valve remains lifted longer, enabling a higher volume of water to enter the bowl for improved waste removal and reduced double‑flushing. A dedicated silicone seating ring enhances the seal between the flapper and flush valve, minimizing leaks and maintaining tank water levels. Built for durability and broad compatibility, this flapper assembly fits most toilets equipped with a 2‑inch flush valve opening and is ideal for restoring or upgrading flush performance.
