What is the maximum pipe size you can use thread tape on?
There are no limitations on the diameter of the pipe. You should always wrap the tape enough times around the male threads in order to fill the spigot (female threads). Any pipe sizes over 1¼” with pressure and fluids moving through it should have the male threads wrapped with tape and then the approved pipe joint compound spread over the tape.
How do I apply pipe thread tape, and are all the tapes applied the same way?
All ½”, ¾” and 1” wide tapes are installed the same way. After you select the proper size of tape for your thread, you will wrap in a clockwise motion, while keeping the tape at the bottom of the thread. For ½”, ¾” and 1” pipe threads you will only need to wrap the threads in a straight pattern 3 to 5 times around the male thread, if the tape width is the same size as pipe diameter. For 1¼” pipe threads and above or when tape width is smaller than pipe size, you will wrap 4 to 5 times starting at the end of threads and working up.
What pipe joint compounds should I use in an approved piping system filled with natural gas?
The following Oatey pipe joint compound products are approved for use in this application: Oatey Great Blue, Hercules Block, Hercules Grrip, Hercules Megaloc, Hercules Pipe Joint Compound, Hercules Pro Dope or Hercules Real-Tuff are all safe for this application.
