Abstract
A plug is adapted for sealing a disposable filter cartridge. The plug is inserted into the axial opening of the cartridge for temporary retention by the grommet. The plug is then reversed and inserted into the grommet of the spent filter cartridge for sealing the contents. The plug is constructed to resist removal from the spent cartridge. A second plug embodiment seals with a sleeve-like grommet at two axial spaced positions.
