1. How many turns of raw tape are usually wrapped
PTFE raw tape is generally wrapped around the joints of pipe fittings to achieve a sealing effect. Many friends do not know the specific number of turns of wrapping, so how many turns of raw tape is appropriate?
In fact, the number of turns of raw tape is not fixed, because different pipe fittings require different numbers of turns. There is no rigid regulation for the specific number of turns. It is usually determined by the thread clearance. As long as it can be tightened and leak-free, it is fine. According to experience, it is generally necessary to wrap more than ten turns to ensure the sealing effect.
In addition, the number of turns of raw tape depends on the thickness of the material itself. For example, if a faucet with 10 turns of raw tape is normally wrapped, 8 turns may be enough if a thicker raw tape is used.
When using PTFE raw tape to wrap pipe fittings, the specific number of turns depends on the thread clearance of the pipe fittings and the material of the raw tape. When wrapping, the number of turns should be appropriate. Wrapping too much may affect the sealing effect; in addition, if the number of turns is too large, the pipe fittings will be bloated and may not be able to be inserted.
3. Will there be water leakage if the PTFE tape is not wrapped enough?
Answer: Yes.
Some friends use raw tape to wrap pipe fittings for convenience, and think that it is good to wrap three or five times, and do not need to continue wrapping. However, in fact, the raw tape may not have a good sealing effect, and water leakage will occur soon.
