The Kohler Genuine 1037307 Tank Gasket is an essential component in a toilet’s tank assembly. Let’s explore its details:

• Function: The tank gasket provides a watertight seal between the toilet tank and the bowl. When you flush the toilet, water flows from the tank into the bowl through the flush valve. The tank gasket ensures that water doesn’t leak from the tank. 
• Design: The design of the tank gasket ensures that it fits properly between the tank and the bowl. It may have a round or oval shape, depending on the toilet model.
• Installation: Installing a tank gasket involves placing it between the tank and the bowl during toilet assembly. Follow the manufacturer’s instructions carefully to ensure proper alignment and sealing.
• Maintenance: Regular inspection is essential to check for any signs of wear or damage. If you notice leaks around the tank, it might be time to replace the gasket.
• Replacement: If you experience water leakage from the tank, consider replacing the tank gasket. Always use genuine Kohler parts for reliable performance.
