Add A Pipe Diameter Measuring Tape To Your Toolbox

What's the diameter of this Pipeline?
What’s the diameter of this Pipeline?

Diameter tape measures are able to give you the diameter of a pipe, pipeline, log, or any other round object. They do it in 1 easy step. All you do is wrap the pipe diameter measuring tape around the pipe and read off the diameter. A regular tape measure would give you the circumference. Then you would have to divide by pi (3.14159). That adds another step, plus you would need a calculator, pencil, and paper to arrive at the diameter.

Why do you need a diameter tape in your toolbox?

  • To measure the diameter of a heater hose in your car, for replacement.
  • To measure the diameter of your round furnace ductwork, so you can extend it, or tap into it.
