About This

• Compatibility: Our flush valve seals are a perfect replacement for Kohler GP1059291 canister flush valve seals. These seals also work as a direct substitute for Kohler canister seals (red and yellow versions)
• Fixed the Leaking Toilet: Replace your old or damaged seal to restore full flushing efficiency to your toilet. Stops weak flushes and leaks caused by a clogged or worn seal—save on water costs
• Premium Silicone Material: Our flush valve seals are made of premium silicone—better than ordinary rubber. They’re more resistant to chlorine and water chemicals, so they won’t corrode easily. Stays shape-stable, rarely forms bubbles, and maintains a tight seal
• Easy to Install: Installs easier than you think—no plumber needed, no special tools required. Our flush valve kit features a lip design that makes fitting the new seal a breeze. Replace flush valve seals in your toilets in minutes
• Great Value Pack: 4-Piece silicone flush valve seals (3.4" outer diameter, 2.7" inner diameter, 0.08" thickness) compatible with Kohler toilet flush valve gaskets (including GP1059291). Perfect for storing as long-term spares
