RFC
Premium thread for small O.D. casing or non-upset tubing.
•  Multiple metal-to-metal seals:
   -14º internal self-energizing primary seal
   -30º torque shoulder and pressure seal
   -90º over-torque shoulder between outer seals
•  Two-step, flush connection.
•  8 pitch-modified buttress threads for the sizes 2-3/8" to 4-1/2"
•  6 pitch-modified buttress threads for the sizes 5" to 5-1/2"
•  Exceeds all API specifications.
The best connection for maximum clearance in high pressure production casing.
•  Swaged and stress relieved plain end tubulars provide
   maximum clearance.
•  Assured high-pressure integrity.
•  Low stress connection for gas and H₂S service.
•  Easy stab-in design prevents cross threading.
•  Excellent anti-galling characteristics under multiple make-
   ups.
•  High torque with reduced turbulence.
•  Low hoop stress with high compressive strength.
