  • Quick-assembly premium connection for pipes of large diameters
  • Opportunity of run-in-hole operations with rotation and casing drilling


Thread profile

  • Easy and deep stabbing
  • Enlarged taper as compared to Buttress
  • Quick assembly
  • Reduced number of turns
  • Two times faster assembly as compared to Buttress thread
  • Reduces risk of cross-threading and prevents the thread from coming off
  • Resistance to scoring wear
  • Tightness due to thread-sealing grease


  • Protection from excessive torque
  • Additional sealing barrier
  • Internally flush connection preventing flow disturbance
  • Ease of assembly until tight, without the make-up torque control
  • Reduces circumferential stresses in the coupling
