Shear Coupling
Shear Rod Coupling is the key component in the successful performance of Sucker Rod String. ASTA Shear Rod Coupling is designed with special safety integral slot key to protect shear from rotational torque, thus can be properly run into Insert Pump, Tubing Pumps and Progressive Cavity Pumps. ASTA Shear Rod Coupling consists of two couplings (male and female section) which comply with API 11 B specification and one shear pin to joint the both sections. The shear pin is made from alloy steel for long product life.
