1. The on off tool packer is made of high-quality materials, and the key areas of the on off tool packer are made of thicker materials and surface hardened to achieve excellent strength. 2. The on off tool packer has special features of fatigue resistance, corrosion resistance, and wear resistance, reducing friction. 3. The on off tool packer enables workers to separate the rod column from the pump without stripping it while leaving the pump downhole, which is simple and convenient.

1. The columnar polished rod centraliser adopts a spiral groove structure design to reduce the sand burial and sand jam problems that are easy to occur in sand-containing oil wells. 2. The centralizing sleeve of the columnar polished rod centraliser can be divided into two materials: metal spray welding and nylon for your choice. 3. The columnar polished rod centraliser can prevent the formation of sediments inside the oil well pipe, so as not to increase the time for well maintenance.

1. The sliding sleeve scentralizer adopts a three-curved surface wear reduction design to change the traditional contact mode. The centralizer increases the contact area of the surface, makes the force more uniform, and improves the anti-eccentric wear performance. 2. The sliding sleeve centralizer is a downhole supporting device. The sliding sleeve centralizer can avoid eccentric wear damage between the sucker rod and the oil pipe and protect the integrity of the oil pipe. 3. The sliding sleeve sucker rod centralizer can center the sucker rod in the well to avoid metal-to-metal contact.
