ABSTRACT:
The diaphragm of the invention is for expansion tanks comprising a pair of shell halves and is for interposition between such shell halves to seal the joint between the shell halves and to anchor the diaphragm so as to divide the tank into a pair of chambers. The diaphragm includes a central sheet of elastomeric material terminating in a peripheral edge that includes an outer peripherally extending column integral with the central sheet and having a pair of integral flange elements and a central web element extending inwardly therefrom. Each of the flange elements is spaced from the central web element to form an annular slot therewith. The slots are dimensioned so as to releasably and sealingly receive the respective skirts of the shell halves.
