Abstract

An exemplary embodiment, among others, of the present disclosure is directed to a drain closure assembly. Such an assembly has a head of the drain closure assembly that is fastened to a top end of a stem, wherein the bottom end of the stem is insertable in a drain shoe. The assembly further includes a gasket fastened around an outer cylinder of the stem below the head. Accordingly, the gasket comprises a series of concentric annular platforms such that a force applied to a top surface of the gasket causes an upper concentric annular platform having a smaller outer diameter to be compressed before the lower concentric annular platform having a larger outer diameter is compressed, thereby creating a seal between the head of the drain closure assembly and the drain shoe.
