Wedge 523™


  • 100% collapse rated thread seal created by full form contact of the dovetail threads, also providing a secondary internal pressure seal rated at pipe body.
  • High compression rating provided by the reverse angle stab flank of the threads makes the Wedge 523™ suitable for the more severe compression applications.
  • Compression strength exceeds tension strength. Wedge 523™ is interchangeable with Wedge 513™.
