What is the Metric equivalent of 1/8 NPT?
For example, an AN 2 fitting will fit a tube with an O.D. of 2/16″, or 1/8″, while an AN 8 fitting will fit a tube with an O.D. of 8/16″, or 1/2″.

Is NPT and Metric the same?
NPT threads are usually longer than Metric or PG and taper toward the end. The taper rate for all NPT threads is 1/16. NPT threads are designed to create a liquid-tight seal upon tightening. The flanks of the threads compress against each other which allow them to form a seal when torque is applied.
Is 1 8 NPT the same as m10x1?
1/8″ NPT has 27 threads per inch and 10mmx1 has 1 thread per mm. So no. They’re not the same!
What does 1/8 NPT stand for?
NPT stands for National Pipe Tapered threads, also known as ANSI/ASME B1. 20.1 pipe threads. It is a U.S. standard for measuring tapered threads on threaded pipes and fittings.
What is the drill size for 1/8 NPT?
If you have a 1/8” NPT pipe tap, the R type is the appropriate drill bit to use with this tap. If the pipe tap is tapered, the ideal drill size is 21/64mm in fraction form or 0.339”. For non-tapered or straight pipe tap, use a drill size of 11/32mm or 0.344”.
Is NPT metric or imperial?
Most pressure gauges around the world have either an NPT or G (metric) connection for insertion into processes.
Is there a metric pipe thread?
Pipe Threads. These metric pipe thread sizes have been adopted by the ISO (International Standards Organization), and are primarily intended for pipes or tubes for screwing together or into ISO pipe ports on valves, cylinders, pumps, and other components.
What is the metric equivalent to 1/4 NPT?

Is NPT measured by ID or OD?
How are they measured? NPT fittings are listed by the “standard” inner diameter (I.D.) of the fitting. (We put “standard” in quotes because the I.D. of the fitting will vary, depending on the manufacturer.) The outer diameter (O.D.) of the threads is usually about 1/4 (0.250) in.
How do you calculate NPT drill size?
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.
What number is a 1/8 drill bit?

| .30 mm | 0.0118 | 1/8″ |
| 83 | 0.012 | 3.20 mm |
How do you identify metric pipe threads?
For Metric parallel threads, taking a caliper reading of the threads outer diameter in millimetres (mm) will give a reading of the exact thread size but not the thread pitch. For example, a caliper reading of 12.03mm indicates it is very likely a 12mm thread.
Are NPT and BSP the same?
NPT and BSP threads are not interchangeable due to the differences in thread forms. NPT threads are pointed in the peaks and valleys, where BSPs are rounded. Most notably, the NPT thread angle is 60 degrees versus the BSP 55-degree angle.
What size hole to drill for 1 8 NPT?
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.
How do you measure NPT fitting?
Despite the variation, you can still measure an NPT fitting. For the male end, measure across the bottom O.D. of the threads. For the female end, measure across the top I.D. of the threads. Your measurement may be different than what is listed in the table.
What is the closest drill bit to 7 16?

Do they make metric pipe threads?
What is metric pipe thread called?
BSPT thread
If your equipment uses INCH tubing, it will most likely use NPT thread. If your equipment uses METRIC tubing, it will most likely use BSPT thread. BSPP – British Standard Pipe Parallel Thread also commonly referred to as G thread is commonly found on equipment made outside of the US.
Can you fit BSP to NPT?
If you are looking to connect a BSP pipe to an NPT pipe, it won’t work. The reason they don’t fit together is that their individual thread designs are different. The NPT design has a 60° angle and the “flattened peak and valley” design pioneered by Sellers.
Can you convert BSP to NPT?
NPT stands for National Pipe Taper and common in the USA and BSP stands for British Standard Pipe and are used widely around the world. NPT and BSP threads are generally not compatible due to the differences in their thread forms.
