Abstract
A tube coupling comprises first and second coupling components each having flow passages terminating in openings formed in transversely extending sealing end faces positioned in aligned face-to-face relationship. First and second threaded nut members are associated with the coupling components and cooperate to drive the sealing end faces together. An annular drive member is located between the first nut member and the first coupling member for conducting axial forces from the first nut member to the first coupling component while preventing relative rotation between the first coupling component and the second nut member. To accomplish this function the drive member has a tapered exterior which wedges in a tapered recess in the second nut member.
