A sucker rod coupling is a mechanical device used to connect two sucker rods together in an oil well pumping system. Sucker rods are long, threaded steel rods that are connected end-to-end to form a continuous rod string. These rod strings are used to transmit the pumping motion from the surface to the downhole pump, which is located in the oil well.

SRLSeries powder mixer for plastic extruder units are widely used for mixing, drying, and coloring for all kinds of plastic resin such as PVC , PE, PP. They can also be applied in drying of engineering plastic such as, ABS, PC, etc. This unit is composed of heating and cooling mixers. Hot material from heating mixer is fed into cooling mixer for cooling to eliminate gas and avoid burning.

The sucker rod coupling is typically made of steel and has internal threads that match the external threads on the sucker rods. It is designed to provide a secure and leak-proof connection between two rods, ensuring that the pumping motion is efficiently transmitted down the well.
Sucker rod couplings come in various sizes and designs to accommodate different rod diameters and thread types. They are typically made to withstand high tensile loads and harsh operating conditions, such as high temperatures and corrosive environments.
Proper installation and maintenance of sucker rod couplings are essential to ensure the integrity and performance of the pumping system. Regular inspections and replacements are necessary to prevent coupling failures, which can result in production downtime and costly repairs.
