ABSTRACT:
A cryogenic fluid conveying device has removable connection of a metal tube and a receptor for the tube. The receptor is formed of a housing member with an aperture therein for conveying the fluid. A tubular member of resilient PTFE has a bore size so as to be slidingly receptive of the rigid tube. A ferrule is disposed on the tubular member which is positioned in the housing member. An annular nut is threaded onto an end of the housing to constrict the ferrule and thereby constrict an annular section of the tubular member. This constriction provides a sealingly tight fit for the rigid tube such that the metal tube can be inserted into and removed from the tubular member.
