Sucker rod coupling, adapter coupling and polished rod coupling adopt high-quality carbon steel or alloy steel. Normally, there are two wrench squares on the coupling and excircle. We can also provide couplings without wrench square. After heat treatment, the hardness of Grade T coupling is HRA56-62, with good corrosion resistance and abrasion resistance. Sucker rod coupling is used to connect sucker rods with same dimension. Adapter coupling is used to connect sucker rods in different sizes or connect polished rod or sucker rod string. Polished rod coupling is used for connecting polished rod and sucker rod. Pay attention to that the use of sucker rod coupling on polished rod will cause coupling cracking.
