How to Properly Apply Thread Seal Tape (Teflon Tape) · Step 1 of 5
In this video
With the old valve removed, thoroughly clean the copper pipe stub-out. Use an emery cloth or wire brush to remove any corrosion, old sealant, or debris from the surface of the pipe. A clean, smooth surface is essential for the new compression fitting to create a watertight seal. Wipe the pipe clean with a rag afterwards.

FAQs
What is the most common mistake when applying thread seal tape, and how do I avoid it?
The most common mistake is wrapping the tape in the wrong direction, which causes it to unravel as the fitting is tightened. Always wrap the tape clockwise around the threads when looking at the end of the pipe, ensuring it tightens onto the threads as the fitting is screwed on.
How many times should I wrap the thread seal tape around the pipe threads for an effective seal?
For most common pipe fittings, 3-5 wraps of tape are sufficient to create a proper seal. For larger threads or those requiring a more robust seal, you might apply 6-7 wraps, ensuring the tape is snug but not overly bulky.
How difficult is this project for a beginner, and what's the approximate cost and time commitment?
This is a very beginner-friendly project. Applying tape to a single fitting typically takes just a minute or two. The materials, like a roll of PTFE tape, are very inexpensive, usually costing only a few dollars per roll.
Do I need any special tools specifically for applying thread seal tape?
While applying the tape itself doesn't require special tools, you will need an adjustable wrench or pipe wrench to properly tighten the pipe fittings after the tape is applied. A wire brush can also be helpful for cleaning old threads before application.
