ABSTRACT:
An expansible tube valve having inlet and outlet body and closures with a generally cylindrical body enclosure between them. A flexible tube embraces a slotted core and integral enlarged beads around the ends of the tube are confined in accommodating annular recesses. Being so confined, the beads serve as retainer means for the tube ends and function also as body seals, being under moderate compression between cylindrical surfaces on the end closures and the interior of the body enclosure.
