Wedge 513®

An integral flush connection designed for production and drilling liners, horizontal and extended-reach wells, and slim-hole applications.

Special applications include drilling with casing, rotating-into-place and during cementing.


  • Available in sizes from 4 ½" to 18".
  • High compression rating provided by the reverse angle stab flank of the dovetail threads makes the Wedge 513® suitable for all liner applications. Compression strength exceeds tension strength.
  • 100% internal pressure rated metal seal maintains gas sealing capability under high axial loads.
  • 100% collapse rated metal-to-metal seal.
  • Wedge 513® is interchangeable with Wedge 523®.
