ToughTorq™ PL5 Spin-Through Coupling
The ToughTorq™ PL5 Spin-Through Coupling† has been specially designed for use with high torque rod applications
such as Weatherford® T66/XD and HD sucker rods and Alberta Oil Tool Drive Rods®††.
Spin-through couplings reduce operating costs of progressing cavity pumped wells. The PL5 centralizer
reduces rod and tubing wear, work over frequency, lifting costs and maintenance. PL5 centralizers are field
replaceable and available with high temperature rotor materials rated to 218 °C.
