Threaded connection is a simple connection method for valve, it is commonly used in small valves. There are two cases:
1. Direct seal: internal thread and external thread directly play a sealing effect. In order to ensure that the connection air-tight, we can use the PTFE sealing tap to be filled at the jointing thread part. PTFE sealing tape is widely used, it has good corrosion resistance, excellent sealing effect and easy to use. When disassembled, it can be removed completely.
2. Indirect seal: tighten the thread, so that it will press the gasket in the middile which will achieve the sealing effect.
