How to Use Plumber Tape: Expert Answers to Plumbing Tape FAQs
If you’re wondering, “What is plumber's tape used for?” or need to know how to use plumber tape, you’ve come to the right place! Plumbing tape, also known as PTFE tape or Teflon tape, is a thin, non-adhesive tape made from polytetrafluoroethylene (hence the term “PTFE”) and is a versatile tool in any plumber's kit. It’s non-adhesive, so it doesn’t stick to anything…and nothing sticks to it, which makes it easy to remove.
What Does Plumbing Tape Do, Exactly?
Plumbers and DIYers use this tape to create a watertight seal on threaded pipe joints and fittings, which helps prevent leaks. It's commonly applied to connections in plumbing systems where pipes or fittings are screwed together. Examples of when plumbing tape is helpful include sealing connections in showerheads, faucets, and pipe fittings.
What is plumbing tape used for? It’s wrapped on plumbing pipes/fittings to create a watertight seal on threaded pipe joints once they’re screwed/fitted together.
When to Use Teflon Tape on Plumbing
When to use Teflon (plumber’s) tape on plumbing depends on the type of joint or fitting. Plumber's tape should be used whenever you connect threaded pipes and fittings. It's particularly useful when a tight seal is essential, such as in water supply lines, gas lines, and air compressor systems. However, it should not be used on compression fittings or any connection that requires a gasket or sealant specifically designed for that type of joint.
How to Use Plumbing Tape: A Step-by-Step Guide
Now that you know when to use plumbing tape, let’s move on to how to use plumbing tape effectively on your DIY plumbing projects. Here's how to wrap plumbing tape to ensure a secure, leak-proof connection:
- Clean the Threads: Before applying the tape, clean the male threads (a term that means the threads are on the outside of the pipe) of the pipe or fitting to remove any dirt, debris, or old tape.
- Start the Wrap: Hold the tape at the end of the threads and wrap it around the threads clockwise (in the same direction the fitting turns to tighten).
- Wrap Tightly: Overlap the tape by half with each pass and wrap it around the threads three to four times, ensuring it’s snug and evenly distributed.
- Smooth the Tape: After wrapping, press the tape into the threads with your fingers to ensure a tight fit.
- Install the Fitting: Screw the fitting onto the taped threads, tightening it by hand first and then using a wrench if needed.
Following these steps, you can effectively use plumbing tape to create a leak-free seal.
