ConeLok™ Precision Connection

  • Innovative torsion bearing geometry eliminates cumbersome polygon keys
  • Interference fit supports torsional loading on entire surface of connection, not just the corners as in a legacy shear coupling
  • Lessens diametrical stress risers improving fatigue resistance
  • Allows use of larger diameter spud

Large Diameter Spud

  • Spud Diameter not limited by minor diameter of polygon key as in legacy couplings
  • Increased diameter increases bulk strength of connection, and also improves fatigue resistance
  • Large Diameter spud is two times stronger than legacy coupling spud in tension, and 2.7 times as strong in bending

Short Shear Pins

  • Short shear pins reduce effect of stress risers associated with through holes, increasing bulk strength and improving fatigue life
  • Eliminates non-reversible bending in shear pins leading to pin fatigue in reciprocating applications
