how to apply teflon tape on pipe threads
1 Start by cleaning the male threads at the end of the pipe with a clean rag. 2  Place the end of the Teflon tape on the second thread in and hold it in place with one hand. 3  Wrap the tape in the same direction of the threads.4  Keep tension on the tape and wrap it several times working away from the end of the pipe. Start at the end (one thread back) and wrap the tape away from the end of the pipe. 2  Use at least 4 to 6 wraps of Teflon tape. 3  For cosmetic purposes, over-wrap past the threads and once the fitting is on peal back any exposed Teflon tape.
