Abstract
In liquid chromatography apparatus including rigid tubes and pliable tubes that convey fluids between various sections of the apparatus, fluid tight connections are made between such tubes by having the O.D. of a rigid tube about equal to the I.D. of a pliable tube, inserting an end of the rigid tube into an end of the pliable tube, providing a short tubular member having a threaded bore that tapers from an opening at one end large enough for the pliable tube to enter to an opening at the other end substantially smaller than the O.D. of the pliable tube, but larger than the O.D. of the rigid tube, sliding the tubular member along the rigid tube until its large opening end engages the pliable tube and then rotating the tubular member so that it threads itself over the outer surface of the pliable tube, deforming it and compressing it against the inserted end of the rigid tube.
