How To Use Teflon seal Tape

Teflon tape is a very thin white tape used to wrap the threaded ends of metal and plastic pipes to lubricate the threads and prevent leaks where pipes join. The thin tape fills the minute gap between the male and female pipe threads stopping water leaks. The alternative is to use pipe dope, a paste type material which also seals and lubricates, allowing for a tighter joint. There is also a another variety of Teflon seal thread tape that is yellow. The yellow tape is heavier and is for use on gas line connections. Never use regular, white, Teflon thread seal  tape on gas connections.

• Clean the pipe threads with a rag before applying the Teflon tape.
• Start wrapping the male threads at very end of the pipe, but do not let the tape lap over the end. If the tape laps over the end of the pipe it can reduce water pressure and even cause clogs from bits of the tape that get pulled into the water line.
• Start with a couple loops around at the end, then wrap all the threads, overlapping half the width of the tape on each wind.
• Wrap in the direction of the threads starting from the end and proceeding toward the length of the pipe. Wrapping the wrong way may result in the tape coming unwound as the fittings are tightened.
• As you wrap, keep tension on the tape so that it is pulled into the threads.
• If you loosen or disconnect a fitting, remove the old tape and re-wrap it with a fresh piece.
