Abstract
A tube closure of elastomeric material having specific properties has an open end, a closed end and a side wall defining a tapering outer frustoconical surface. The side wall has a predetermined thickness at its thinnest point, which is determined in connection with the angle of taper of the outer frustoconical surface and the properties of the elastomeric material to provide a seal with high integrity over a range of tube sizes. The closure has a radially extending flange of predetermined thickness by which the closure can be removed from a tube by a pushing force. The closure has an inner surface for sealing against an outer surface of other tubes.
