The Danco 40079B Flush Valve Spud Gasket is an essential plumbing repair component designed to stop leaky toilets. This gasket fits inside the toilet at the base where the tank drains into the bowl, creating a watertight seal that holds water in the tank and keeps the tank solidly attached to the bowl. Replacing a worn-out gasket prevents leaks between the tank and the bowl.
