Kohler’s Class Five flush system delivers a powerful, high-performance flush that clears the bowl completely — but only when the flapper seals and lifts correctly. A worn or warped flapper leads to a constantly running toilet and diminished flush power. This direct OEM replacement restores the precise seal and lift the Class Five system demands.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eGenuine Kohler OEM replacement — designed specifically for Class Five two-piece toilet flush systems\u003c\/li\u003e\n\u003cli\u003eMaintains the exact seal geometry and lift profile required for Class Five performance\u003c\/li\u003e\n\u003cli\u003eStops running toilets caused by a degraded or leaking flapper\u003c\/li\u003e\n\u003cli\u003eChlorine- and mineral-resistant rubber construction for long service life\u003c\/li\u003e\n\u003cli\u003eDirect drop-in fit — no cutting, trimming, or adapters required\u003c\/li\u003e\n\u003cli\u003eRestores full flush power and water efficiency to your two-piece toilet\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhy Replace Your Flapper?\u003c\/h3\u003e\u003cp\u003eThe flapper is the most commonly replaced toilet part — and for good reason. On Kohler Class Five two-piece models, a degraded flapper not only causes a running toilet but can also reduce flush effectiveness. The GP1078441 is the correct OEM flapper for two-piece Class Five toilets, ensuring the valve opens fully and seals completely with every flush. A simple swap can save thousands of gallons of water annually.\u003c\/p\u003e\u003ch3\u003eCompatibility\u003c\/h3\u003e\u003cp\u003eDesigned for Kohler Class Five two-piece toilets.
