Sucker rod couplings with wrench square.
Sucker rod couplings with smooth surface
According to different needs, RockySea Petro provides users couplings under different processes. All of the three types have two surface treatment classes: class T and class SM. The class T stands for through-hardened and the class SM stands for sprayed metal. The outer diameter of the sucker rod couplings has FS(full size) and SM(slim hole) types.
The main types of RockySea Petro rod couplings include sucker rod couplings, polished rod couplings and sub-couplings. The Sucker rod coupling has same box thread size in both end. The polished coupling is designed to connecting polished rod and sinker bars. The sub-coupling is also called cross over coupling. It has different box thread size in both ends.
