ABSTRACT:
A rotary coupling for connecting tubular members is disclosed including a first tubular base member having external threads and a second tubular member with one end telescopically mounted within the first tubular member. Near the lower end of the second tubular member there is provided an exterior circumferential bead and a bearing member shown as a split ring is provided which encircles the lower end of the tubular member and holds it against relative axial movement. An O-ring seal is also fitted over the second tubular member within the bearing member. A retaining nut encircles the second tubular member and threadably engages the external threads of the first tubular member. When the nut is tightened, the bearing member axially grips the bead, with a lip on the bearing member engaging the bead flexing so that the telescoped members can still rotate relative to each other.
