ABSTRACT:
A liquid separation tube having a tubular membrane inside of a porous support tube and an end part which is insertable into a coupling member has a seal structure which allows the use of a relatively thin adapter which is to be inserted within a packing. In the seal structure, annular grooves are provided on either the outside circumferential wall of the adapter or the inside circumferential wall of the packing and passages are formed through the adapter in the vicinity of the annular grooves so that a pressurized feed solution can expand the packing in the vicinity of the annular grooves to provide a seal between the packing and the tubular membrane.
