What is the diameter of 1/8 NPT?
You can prefer this chart to see the list of the diameters of the 1/8 NPT, and the calculations are mentioned here clearly for your reference.
How do you calculate NPT Drill size?
Typically, for Metric threads, the tapping drill can be calculated by deducting the pitch from the thread diameter. For instance, the tapping drill for an M5x0.75 thread is 5-0.75mm = 4.25mm.
The diameter less the pitch is used to determine the tapping drill size for imperial (inch) threads. example: 16.5mm for 3/4.10 UNC pitch = 0.1, diameter = 0.75, and tapping drill = 0.65.

How deep do you tap an NPT thread?
The majority of common pipe taps have a maximum chamfer length of three to four threads.
As a result, the recommended tapping depth is approximately 5 threads for “hand tight,” 3 threads for “wrench tight,” and 4 threads for the chamfer, for a total of approximately 12 threads.

Do NPT threads need Teflon tape?

How to Remove a Bolt with Stripped Threads
How to remove a bolt with stripped threads? It is impossible that you’ve never experienced removing a bolt with stripped threads. Some do not take much time [especially relatively small ones], but sometimes you get fully disappointed because they are over-tightened because of the rust. itismycar.com
Are NPT threads tapered?
Both the male and female NPT threads are tapered, and they can be sealed with Teflon tape or jointing compound.
Two categories of pipe threads are used in hydraulic circuits: Jointing threads are either taper external and parallel or taper internal threads that are used in pipes to create pressure-tight joints by sealing on the threads.
Do you torque NPT threads?
For sizes up to 1 inch for NPT fittings, a general rule of thumb is to tighten 2-3 full turns after hand-tight engagement.
Between 3.5 and 6 threads should be engaged. Any value outside of this range could be an indication of threads that are not within tolerance or that the joint has been improperly tightened.
What is nominal hole diameter?
The nominal diameter is the dimension that people most frequently associate with screw threads.
Nominal diameter is less of a measurement and more of a label. A bolt and nut, for instance, might be said to have a diameter of 1/2″.
However, neither the bolt’s external threads nor the nut’s internal threads are precisely the same. 500 ins across.
