Shear couplings are used to reliably separate the rod string from the bottom hole assembly when the pump seizes or the rod gets stuck. The WireTorq™ Shear Coupling is an innovative solution to enhance shear coupling run life in challenging applications such as horizontal PCP wells with some dogleg severity. This downhole tool decouples bending and torsional forces from the shearing mechanism to improve the overall fatigue life. Sizes Available in standard API sucker rod sizes 7/8" (22 mm) 1" (25 mm) Shear ratings Available in industry standard loads 35,000 LBF (156 kN) 40,000 LBF (178 kN) 45,000 LBF (200 kN) Features • Increased flexibility in torsional direction should improve fatigue life in challenging PCP applications • Integrated torque transmitting key with large bearing surface • Box by Box ends assemble easily with sucker rod • ISO 9001 ensures full material and manufacturing traceability • Threads are formed (cold rolled), not cut, conforming to API 11B • Compact design • Patent pending
