Abstract
A tube coupling comprises first and second coupling components having transversely extending sealing end faces in aligned face-to-face relationship. First and second nut members are arranged to drive the sealing end faces toward each other. An annular anti-twist member is located between the first nut means and the first coupling member for conducting axial forces from the first nut member to the first coupling component. The annular anti-twist member and the second nut member include axially engaged portions for preventing relative rotation therebetween.
