Flush OD connection facilitates running
and circulating and eliminates down hole
coupling face hang-up. Boxes machined
onto as-received pipe ends.
Exceptional torque strength developed
through the simultaneous engagement
of opposing flanks of the dovetail thread,
permitting washing and drilling operations.
100% internal pressure rated metal seal
maintains gas sealing capability under
high axial loads.
The shallow angle run out chamfer on the
pin ID promotes uniform stress under the
seal around the full circumference.
