Create a Sketch on the new face of this extrusion and draw a Circle equal to the inner diameter of the pipe. National Pipe Thread Taper, commonly known just as NPT, is a U.S. standard for tapered threads used on threaded pipes and fittings. This standard is widely used all over North America. Pipe thread sizes are usually based on the inside diameter (ID) or flow size. The way to read an NPT size is the nominal inside diameter and the number of threads per inch. For example, if we have a 1/4-18 NPT, that means it is a 1/4 inch inside diameter and 18 threads per inch. If LH is added to the end, it means the pipe has a left-handed thread.

For other types of tapered threads such as Aeronautical National External Threads, ANPT, the end must be chamfered 45° with a specified depth define in the ASE AS71051 Standard. At the bottom of the PropertyManager of the Hole Thread, the text can be edited to any note and can be later automatically imported in the 2D drawing of the model. First up, we have the trusty old steel taps. These bad boys are a reliable option for those on a budget but remember that they might not be the best choice for heavy-duty or precision work. Taper of Thread: The taper on all NPT Thread is 1 in 16, or 0.75” per 1 foot, with the center line bisecting the angle created. The corresponding half-angle of the taper relative to the center line is 1 degree, 47 minutes or 1.79°. NPT is defined by ANSI/AMSE standard B1.20.1, and in this article we’ll be specifically referencing the ANSI/ASME B1.20.1-1983, including its charts and tables.

I hope this information was useful and will hopefully come in handy for those of you looking for the answer! The 1/8″ NPT tap’s diameter is not 0.125 inches, but based on the thread on the end of a 1/8-inch pipe, it’s approximately0.405 inchesin the “big” diameter. If you’re working with a 1/8″ NPT tap, one of the key things you need to know is the correct drill bit size. So, let me clear that up for you!

Taps could have various coatings like TiN (titanium nitride) or TiCN (titanium carbonitride), enhancing their performance and longevity. Width of Flat, F: Width of the flat caused by truncation, or shortening of the thread crest or root. Now, for the drill bit size, the secret lies in subtracting the pitch of the thread from its diameter. For a 1/8″ NPT tap, the magic letter is anR-shaped drill bit. Now, before drilling, mark the spot where you want your hole. That way, you know exactly where your drill is going, and you minimize any errors. Plus, it keeps everything looking neat!Create a Sketch on the rear face of the extrusion and draw a circle equal to the outer diameter of the pipe. These coatings can get a little pricey, but trust me; they’re worth it if you want to up your game. Pitch, P: Corresponding to the Threads per Inch of the given pipe, e.g. this 1-1/2 NPT Pipe Size at 11-1/2 Threads per Inch will have a pitch of 1÷11-1/2 or .087. I cannot stress enough how important it is to lubricate when drilling! Trust me, lubrication prevents overheating, reduces friction, and helps prolong the life of your drill and tap. So don’t skimp on the lube! Once we open up the Hole Wizard feature, select the Tapered Tap option in the Hole Type section. Set the standard to ANSI Inch, set Type to Tapered Tap Pipe Tap and in the hole specifications, select the desired size in inches.

With this sketch falling on the origin, normal to the central axis, draw a C ircle concentric to the origin with a diameter equal to the outer diameter of the pipe. First, you’ll want to ensure you got the right size drill bit. In our case, we need anR-shaped drill bit equivalent to 0.339 inches or 8.61 mm.In NPT threads chamfers are not required, although a chamfer may be present, there are no specifications on the angle and depth of the chamfer. Choosing the right tap material is crucial for a successful tapping job, especially when working with a 1/8 NPT tap. So, let’s talk about the best materials to ensure you get it right the first time! I recommend high-speed steel taps if you’re looking for something with a bit more oomph. These are specifically designed for fast cutting and feature excellent wear resistance.
