ABSTRACT:
A threaded union for tubulars used for high-pressure fluid applications includes a unitary nut supported by at least two nut retainer segments received under a top wall of the nut in an annular segment retainer groove in one of the tubulars. The nut retainer segments fully support the unitary nut. The nut retainer segments are held in the annular segment retainer groove by limiting travel of the nut or by securing the nut retainer segments in the segment retainer groove.
