NPT Thread Information:

When does 1 Inch never measure 1 Inch? Answer: when we are working with pipe threads.

  • NPT is an acronym for National Pipe Thread. NPT threads are tapered. The taper improves joint sealing.
  • NPT pipe thread sizes do not correspond to actual inch measurements. For example a 1” NPT Pipe Thread measures 1.315”.
  • Coyote Gear staff hopes this information helps people who are new to piping products get the size parts they need.
