How to find the correct pipe thread size

  • WARNING: The NPT thread size is NOT referring to the size of the thread itself!
  • The plumbing industry standard for the pipe sizes is NOT always as straightforward as measuring the pipe.
  • Measuring the pipe will often mislead you into choosing the wrong pipe size.
  • The "pipe thread size" is measured and based on the inside of the pipe.
  • A lot of people measured the thread / the opening for the thread / outside diameter of the pipe, and thought that was the thread size. It was WRONG.
