ABSTRACT:
The present invention relates to a filter bag holder comprising a flexible tubular member having a relatively constant outside diameter throughout a substantial portion of its length to one of its axial ends and having two axially spaced annular ribs protruding from the outside of the tubular member near its other axial end. The constant-diameter end may be attached to a filter bag, and the ribbed end engages in the region between the two axially spaced protruding annular ribs with a rim around an aperture in a partition located between mediums under different pressures.
