Thread Tape:
Well, one of the reasons one of the machines I am working on, is the leaks in the system ??
Guess what; THREAD tape every where and lots of it.... Like bunches of grapes and soft fluffy pillows on every fitting, along with signs of leaking and crap oozing out.
A: Most of it has ended up being pushed off the thread and thus nothing more that a lump of ptfe trying to act as an external washer

B: Also some bits in one solenoid..
Application Instructions for PTFE Pipe Thread Sealing TapePlace end of tape on pipe thread 1/8” from end of pipe.
1. Wrap tape around pipe with 70% overlap = 3 layers all the way around the malethread. Stretch tape enough to pull into the thread without causing the threadtape to shred. Overlap back to the starting point.
2. Press tightly on tape and break it. Pipe thread is now ready for joining.
3. Joint should be tightened according to the fitting or device manufacturers’ specifications.
NEVER USE PTFE PIPE THREAD SEALING TAPE ANDPASTE TOGETHER.Seal integrity will depend on the quality of the male and female thread, fluidpressure, and the nature of fluid being sealed. The 70% overlap is acceptable undernormal water use with fixtures in normal repeated use condition. Higher riskapplications may require greater overlap or the use of high density thread sealingtape.
*************
NOTE: In the trade we were also taught that it goes on, so that when tightening the joints, it does not catch and push the tape off and into a bunch...
Hold the end of the tape flat against the pipe threads, flush with the end of the pipe, then turn the pipe clockwise, or as though you were tightening it ( R/H or L/H thread makes a difference.) .
Put 1-1/2 to 2 turns of tape on the pipe, keeping the tape flat and tight against the pipe as you turn, and overlap as per above.
The reason for doing it this way is so the loose end gets pinned down by the action of screwing the pipe in, rather than getting flipped up and pushed off.
Same for when doing the tape mods to Rocky grinders.
WiKi - Over-use, or mis-application of thread tape may be a hazard. As the tape material is so soft, excess or overhangs may easily break off and form a foreign body contaminant that could jam a valve seat etc.
OH so true....
