Technology That Runs Deep
CONVERTIBLE
LTC or Buttress
Specialty Casing Connections

CONVERTIBLE
Convertible ring provides a flush bore, axial
metal seal and a positive torque stop
API Buttress
Threadform
API 8 Round
Threadform
Enhanced Performance from API
Buttress and LTC Threadforms
The close-tolerance convertible coupling and axial ring
provides enhanced bending, torsional and sealing
performance.
Convertible Ring
Provides a positive torque stop for repeated make-up.
SealLube
This anaerobic compound locks the coupling in place
and increases the sealing efficiency of the threads.
Horizontal and Deviated Wells
The close-tolerance coupling in conjunction with the
