Plumber shows how to apply teflon tape and thread sealant

What happens here

To correctly apply Teflon tape, first, insert your index finger into the center of the tape roll and run the loose end of the tape over your middle finger. Position the pipe's threaded end on top of the tape, making sure to start the tape one or two threads in from the very end of the pipe. Crucially, wrap the tape in a clockwise direction around the threads. This ensures that the tape tightens onto the threads rather than unwrapping when the pipe is screwed into a fitting. Apply approximately 3 to 5 wraps of tape, ensuring each wrap overlaps the previous one slightly to create an even layer. Once sufficient wraps are applied, gently pull and break the tape to separate it from the roll. After breaking off the tape, use your fingernail or finger to lightly press and mold the tape into the first thread to secure it.

Goal: Properly wrap Teflon tape onto the pipe threads for a tight seal

Tools and materials

  • Teflon Tape Thread Seal — To provide the primary seal on the pipe threads
  • Threaded Pipe — The pipe whose threads are being prepared for sealing

together so the first thing we're gonna do is we're gonna take the teflon you just put put your index finger in the front and just run it over or your middle finger take the pipe and set it on top of the Teflon you're going to be going clockwise make sure that when you would apply your teflon you're going clockwise if you don't apply the teflon clockwise it's going to back out whenever you go to put your fitting then so then you just want to keep going you're looking for about three wraps minimum I like to go for maybe five and then just break it off so what I do then is I just take my fingernail lightly put it in the first thread and then I start moving and you can watch as it goes into the threads okay so now that that's all hooked up and you know it's together then you're just gonna take a little bit of your thread sealant and you're just gonna go
