1. The PTFE tape needs to be wound along the thread direction, which greatly reduces the sealing performance;

2. Do not wrap all the threads around the PTFE tape, otherwise the PTFE tape will enter the pipeline and reduce the sealing performance. We need to start winding from the second thread at the beginning of the thread and leave the first thread out;

3. When winding the PTFE tape, you need to use a little force to ensure that the PTFE tape is not wound when it is not broken, and the PTFE tape wrapped in this way is tight and firm enough to ensure the sealing;

4. As for how many times the PTFE tape is wound, I believe that the master must have his own experience, but here is a reminder to remind everyone that the thickness of the second half of the winding PTFE tape is larger, that is, the front is thin and the back is thick, so as to ensure that the thread is tightened and tightened, and the sealing performance is increased;

5. After the PTFE tape is wound, do not withdraw the threaded pipe once it is tightened, otherwise it needs to be rewound and tightened
