A polymeric rod guide for a sucker rod, said polymeric rod guide having a body surrounding and coaxial with the sucker rod and molded in fixed contact with the rod. The body having a polygonal cross-section and a plurality of blades longitudinally disposed and extending from the body, each blade having a pair of planar longitudinal side walls and an exterior longitudinal edge, each of said blades having a first blade face disposed between a first terminal end of the blade and the exterior longitudinal edge and a second blade face disposed between a second terminal end of the blade and the exterior longitudinal edge, and an area of the body between the longitudinal side wall of a first blade and the longitudinal side wall of an adjacent second blade defines a trough having a plurality of planar surfaces.

Sucker rod guide

A sucker rod including a sucker rod body (); a transition section () having an outer surface disposed circumferentially around the longitudinal axis of the transition section, the outer surface having a longitudinal profile comprising a continuous curve beginning at the cylindrical outer surface of the rod body and having a concave curved portion having a radius (R) and a convex curved portion having a radius (R), wherein Ris less than Rand a diameter of the transition section measured transverse to the longitudinal axis (AA) is continuously increasing with distance from the outer surface of the rod; a wrench square section () having at least four wrench flats (); a pin shoulder section () having a pin shoulder face () adapted to contact an end of a coupling () the pin shoulder face having an outer diameter (D); and a threaded pin connection section () having male threads.
