How to Apply Teflon Tape the RIGHT Way

Applying Teflon tape correctly is essential for creating a tight, leak-free seal on threaded pipe connections. To apply it properly, face the threaded male end of the fitting toward you and wrap the Teflon tape in a clockwise direction, the same direction the fitting will tighten. Start wrapping at the bottom of the threads and work your way up, overlapping the tape by at least half its width with each pass. Continue wrapping until you reach the end of the pipe, ensuring the threads are evenly covered for a secure seal.

Step-by-Step Instructions

1. Position the fitting correctly
   Hold the male-threaded end of the fitting so the threads are facing you.

2. Wrap in the correct direction
   Wrap the Teflon tape clockwise, the same direction the fitting will be tightened. This prevents the tape from unraveling during installation.

3. Start at the base of the threads
   Begin wrapping at the bottom of the threads and work your way upward toward the end of the pipe.

4. Overlap the tape evenly
   Overlap each wrap by about 50% of the tape’s width to ensure full coverage.

5. Finish at the end of the pipe
   Continue wrapping until you reach the end of the threads. Smooth the tape into the grooves with your fingers for a secure fit.

Where to Use (and Not Use) Teflon Tape

Teflon tape is ideal for threaded pipe connections in plumbing, water, and wastewater applications.

Do not use Teflon tape on:

• Compression fittings

• Hoses

• Fittings with O-rings or gaskets

These connections seal without thread tape and using it can cause leaks or improper sealing.

Pro Tip 💡

Leave the first thread at the end of the pipe exposed. This makes it easier to start threading the fitting and helps prevent cross-threading.

Teflon tape can be used just about anywhere where you have threads. Avoid using Teflon tape with compression fittings, hoses, or applications that have an O-ring or gasket.

PROTIP: Try to leave the first thread at the end of the pipe exposed as it is easier to attach the fittings.
