Score: 88/100Rankings

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 Kohler GP85160 is a genuine 2-inch blue toilet flapper featuring an integrated adjustable float, designed specifically for 1.6 GPF two-piece Kohler toilets. It offers a tight seal to prevent leaks and includes durable, chlorine-resistant vinyl construction for long-lasting performance. The product comes with a 5-year warranty and is intended as a direct replacement for failing flappers in compatible models.
