Teflon Tape - How To Use Teflon Tape

By

Teflon tape is a great way to ensure that you get a water tight seal on pipe joints. When used correctly, Teflon tape can help ensure that threaded connections come together smoothly as well as preventing leaks. To help get the most out of your Teflon tape application you need to make sure you are using it correctly.
  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.
  5. When you have finished wrapping the Teflon smooth the loose end down into the threads.
Learning where to use Teflon Tape is just as important as learning how to use it.

Where To Use Teflon Tape:

  • Use Teflon Tape on any threaded connections that don't have a built in rubber seal.
    • Shower Arms
    • Shower Heads
    • Threaded Tub Spouts
Where Not To Use Teflon Tape:
  • Any Gas Connections or threaded connections with a built in rubber seal.
    • Faucet Flex Lines
    • Water Heater Flex Lines
    • Flared Fittings
Tips For Using Teflon Tape:
  • Always wrap the tape in the same direction that the fitting will be tightened
  • Don't apply Teflon to the first thread
  • Start at the end (one thread back) and wrap the tape away from the end of the pipe
  • Use at least 4 to 6 wraps of Teflon tape
  • For cosmetic purposes, over-wrap past the threads and once the fitting is on peal back any exposed Teflon tape.
