l SUCKER ROD
-Hollow/Solid Sucker Rod
-Sinker bar (Heavy Weight Sucker Rod)
-Polish Rod
-Surface Anti-Corrosive Sucker Rod
A sucker rod is a steel rod, threaded at both ends, used in the oil industry to join together the surface and downhole components of a reciprocating piston pump installed in an oil well. The pump jack is the visible above-ground drive for the well pump, and is connected to the downhole pump at the bottom of the well by a series of interconnected sucker rods.
