How to use: 1. Before use, check whether the thread type at both ends is consistent with the type of the drawing design (the thread of the connecting member on site).

2. Clean the thread and check whether there are bumps, cracks, inclusions and other defects on the thread surface.

3. Evenly apply special thread sealing grease for petroleum tubing and casing to the threads at both ends. Manually rotate the threads at both

 ends that need to be matched to make the threads fit tightly.

4. Use a tightening device with torque display to rotate the two threads to the torque specified by the API standard to prevent leakage.
