Wedge 623® RW


The highest wear resistance with unrivaled running reliability and robustness.

The TenarisHydril Wedge 623® RW presents greatest resistance to wear typically needed in the most severe deepwater and high pressure applications. It offers exceptional torque capability and compression efficiency due to the simultaneous engagement of opposing flanks of the dovetail thread. This integral connection is also compliant with the API RP 5C5 CAL-IV testing protocol taking into consideration physical testing on both worn and non-worn casing.


  • Available in sizes 9 7/8" to 16 1/2"
  • TenarisHydril Wedge thread design providing unrivaled running reliability and robustness
  • Internal and external pressure seals (metal-to-metal) in line with API RP96 for deepwater applications:

     -100% external pressure seal for added reliability
     -100% internal pressure rated metal seal maintains gas sealing capability under high axial loads, with enhanced resistance to wear
  • Outstanding torque capability and compression efficiency
  • Tested under the API 5C5 CAL-IV protocol, the Wedge 623® RW connection provides validated reliability under combined loads, even under conditions where wear is present.
  • No drift restrictions after over torque.


  • Dopeless® technology.


  • Offshore/Deepwater
  • HP/HT and deep wells
  • Intermediate casing
  • Liners and tie-backs
