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 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.
