API 11B Oilfield Sucker Rod and Polished Rod Couplings
Polished rod couplings are designed for connecting of the polished rod to the top rod of the string. Contrary to rod couplings, polished rod couplings have a female cone that eliminates the coupling twist-off in the course of operation.
Sucker rod coupling is used to connect two sucker rods. The grade is API Grade T.
Spray metal couplings are better in anti-corrosion than common sucker rod couplings.
Slim hole and full size couplings are available.
