A 1/8″ NPT tap requires an R-shaped drill bit. The R drill bit corresponds to a size of 0.339 inches or 8.61 mm.
How do you determine NPT fitting size?
To determine the NPT size, with a caliper, measure the diameter of the 2nd or 3rd thread on your pipe, fitting or valve as shown below. Find the caliper measurement in the chart and cross reference the nominal NPT pipe size. Don’t get confused, the actual measurement is not the same as the NPT pipe size.
Is MIP the same as NPT?
Yes, NPT (national pipe thread) has the same thread dimensions as an MIP (male iron pipe) and FIP (female iron pipe).
What does NPT mean in plumbing?
The best known and most widely used connection where the pipe thread provides both the mechanical joint and the hydraulic seal is the American National Pipe Tapered Thread, or NPT. NPT has a tapered male and female thread which seals with Teflon tape or jointing compound.
What is NPT thread size?
NPT is defined by ANSI/ASME standard B1. 20.1. The taper rate for all NPT threads is 1 inch of diameter in 16 inches of length ( 3⁄4 inch per foot or 62.5 millimeters per meter) measured by the change of diameter (of the pipe thread) over distance of thread.
How deep do you tap NPT?
Most standard pipe taps have a maximum chamfer length that ranges between 3 and 4 threads. Therefore, the tapping depth should be the approx. 5 threads for the “hand tight”, 3 threads for “wrench tight”, and 4 threads for the chamfer, or approx. 12 threads total.

How do you determine the drill size for a tapped hole?
As a rule of thumb, for Metric threads, the tapping drill can be calculated by subtracting the pitch from the diameter of the thread. eg for an M5x0. 75 thread the tapping drill is 5-0.75mm = 4.25mm. For Imperial (inch) threads the tapping drill size is calculated in the same way, diameter minus pitch.

Should you use Teflon tape on NPT fittings?
NPT threads are designed to be used with a sealing compound such as Teflon tape to create a leak-free seal, whereas NPTF threads form a mechanical seal by crushing the entire thread form. If NPT is used without a sealing compound then there can be leakages or other unpleasant issues.
What is the difference between NPT and MNPT?
NPT stands for National Pipe Thread and is an American standard thread. It may also be reffered to as MPT , MNPT or NPT (M) for male external threads and FPT, FNPT or NPT(F) for female interal threads. Both threads have the same pitch, angle (60 degrees) and shape (flat peaks and valleys).
What is a NPT adapter?
NPT (National Pipe Thread) seals are the most popular type of seal for pressure calibration systems in the U.S. and Canada. NPT male adapters have a taper thread that wedges into the female NPT adapter. Any more than that and the seal can leak around the thread sealant.
