ABSTRACT:
A one piece gasket for a toilet which eliminates the use of separate sealing washers and spacing devices is disclosed. The one piece gasket is formed with flange portions extending from a central sealing portion and has upstanding connectors (with fastener through bores) extending from the flange portions. The connectors can have an enlarged washer head and a bumper element. The washer heads provide an expansion fit into tank fastener holes for preliminary positioning of the gasket. In a preferred manner, the washer heads are of a frusto-conical configuration.
