Danco 80857 Tank-To-Bowl Spud Gasket, 2-3/8 in ID x 4-3/16 in OD Dia, Rubber, Black

Repair your leaky toilet with the Danco spud gasket for Kohler. The spud gasket fits inside the toilet on the base where the tank drains into the toilet bowl, forming a seal to hold the water in the tank. Replacing a worn out gasket will keep the toilet tank solidly attached and prevent leaks between the tank and the bowl.
