Clearance OD 1.5–2% of specified pipe body OD (0.5–1% larger than API maximum) for clearance situations.

Exceptional torque strength developed through the simultaneous engagement of opposing flanks of the dovetail thread.

100% internal pressure rated metal seal maintains gas sealing capability under high axial loads. Patented seal saver protects pin seal from handling damage and acts as a stiffener to improve metal seal functioning.

Features

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™.
