Premium thread for large O.D. casing.
•  O.D. is 1% over API nominal for standard connections.
•  Multiple metal-to-metal seals:
   -14º internal self-bleeding/self-energizing primary seal
   -14º self-bleeding external pressure seal with a 90º shoulder
   -14º reserve-angle torque stop between outer seals
•  Two-step, flush connection(per pending API specification 5A).
•  6 and 4 pitch-buttress threads.
The best large O.D. connection for maximum clearance in high pressure production casing.
•  Plain end tubulars provide maximum clearance
•  Connection tension efficiency, burst and collapse ratings are
   not dependent on API tolerances.
•  Customized thread design for each weight of pipe provides
    maximum tensile efficiency.
•  Assured burst and collapse integrity.
•  Larger bearing surface for heavier weights of pipe.
•  Easy stab-in design prevents cross threading.
•  Excellent anti-galling characteristics under multiple make-ups.
