Sucker rod is the common equipment in the oil extraction. It is manufactured through many process including the testing, straightening and forging. The sucker rod is placed between the polished rod and oil well pump. To deliver power. Sucker rod is manufactured from high quality carbon steel and alloy steel, which is conform to the API Spec 11B standard. Sucker rod has various types including the common sucker rod, hollow sucker rod and FRP sucker rod. Commonly we use the sucker rod coupling to connect the sucker rod. The sucker rod also has various specs to fit different environments and applications

Sucker Rod Coupling is a joint for Sucker rod, used in oil well downhole for oil pumping and Production. Yunsheng sucker rod couplings are manufactured from high quality Alloy Steel AISI 5140, fully in accordance with API Spec 11B standard, including class SM coupling, class T coupling, Sub coupling, Full Size, Slim Hole and Over Size, and the thread size are available at 5/8â??, 3/4â??, 7/8â??, 1â?? and 1 1/8â??.
