Mansfield 630-0204 2" SmartFasten Tank to Bowl Kit (Black);

Includes tank to bowl gasket, three patent-pending bolts, three nuts and ballcock coupling nut: Hassle Free: The bolt locks in place, so no reaching into the tank while tightening the nuts. Washer Free: A rubber seal is already molded onto the bolt. Rust Free: Since the bolt's head is rubber, water never comes into contact with metal. Please note: The 2" and 3" versions look similar, the only difference is size of the gaskets. Gasket measurements refer to the size flush valve they will fit.
