A union for connecting two tubular members. The first tubular member has an external flange, and the second tubular member has a set of external threads. An annular nut surrounds the first tubular member. The nut has an internal flange that surrounds the first tubular member, and a set of threads to engage the threads of the second tubular member. Arcuate segments are circumferentially mated between the internal flange of the nut and the external flange of the first tubular member. A flat conical surface on the inner side of the segment comes into contact with a flat conical surface on the outer side of the external flange. Curved conical surfaces tangentially align with and extend from the flat conical surfaces on the segment and the external flange. Cylindrical surfaces tangentially align and join the curved conical surfaces on the segment and the tubular member.
