Abstract
An adapter for a water supply system includes castlellations around the periphery of the mounting hub. The castellations eliminate the continuous sealing surface required for a standard filter end cap to effective seal to the adapter. The mounting hub has ribs on the internal periphery to prevent insertion of filter cartridge end caps with a flat O ring seal or with an O ring seal around the periphery thereof.
