Hasn’t it ever happened to you that you had a fitting or a thread, and you had no idea what fitting it was or what threads it had?


There are an incredible amount of characteristics.

If it is NPT or BSPT

If it’s BSPP or if it’s Metrico

Or if it is SAE or DIN 2353

Or if it is Gas or if it is NPTF

Well, it wouldn’t hurt to have a thread identifier when they put the adapter on your hand.

That’s why today I bring you one of those eye-opening articles, and as soon as I finish explaining everything that the fittings identifier can do, you will ask me for the number so I can send you one.

And if you’re a little geeky like me, you can give it as a gift to your co-workers or your boss on Labor Day (which always looks good).

Well, let’s get to the point. You have entered this page because you want to know if you need it. Spoiler alert: YOU DO.

Let’s get down to business.

What is the thread identifier?

The fittings identifier is a template that can be made of various materials such as plastic or metal to identify what type of fitting you have on hand. It is not a gauge, but it allows us to know what diameter we have in front of us, the thread pitch, and if it is an NPT thread. It is not difficult to use, and it does not weigh anything.

What type of fittings can you identify?

The fitting identifier adapts to many types of fittings by centralizing all the work in the identification kit. It can identify JIC, ORB, NPT, ORFS, BSPP, BSPT, JIS, HIAB, Komatsu, Kobelco, DIN Metric, 60 Fegree Metric, Chinese GB 74, GB Flat Face, and many more. And if you also need to know the difference between BSPP and BSPT, I leave the link to an article here so you can inform yourself (It reads very fast, and everything is crystal clear).

Our thread identifier lets you know what diameter we have from 1/8 NPT to 11/2 NPT; the thread pitch and the measure are male or female.

How to use the thread identifier?

Each tool includes ports to identify female threads, ports to identify male threads, thread pitch gauges (both threads per inch and distance in mm between threads), and unique nose cone and chamfer testers capable of checking 30°, 60°, and 24°. It comes in a high-quality vinyl pouch for easy storage.

Step by step to use the thread identifier

It is very easy to use. You need to know how to use it and have it in a minute. Besides, you have to get used to it. The more you use it, the sooner you get it.

In summary, these are the steps to follow:

  1. Place the male thread into the port holes or the female thread into the posts and note the closest size match.
  2. Align the threads of the fittings with the thread gauges and note the closest match.
  3. If the fitting has a taper or chamfer, align with the 30°/60° chamfer/flare seat section of the BSP tool and note the closest match. If the thread is DIN Metric, you can use the 24° chamfer tester on the Metric tool to verify that the chamfer is 24° but will not indicate a size.
  4. Refer to the table for tools to verify the match between the thread size and the corresponding thread pitch.

Female threads

Insert the ports into the female threads until the closest match is found until the most significant match is found. For British tapered female threads, post 2 to 4 threads deep.

Male threads

To identify male threads, insert them into the ports until you find the closest match. For British tapered male threads, the thread will bottom out anywhere from 2 threads to somewhere in the middle of the thread.

Gauge thread

Align the threads next to the thread gauges until you find the closest match. This section of the tool cannot gauge female threads. However, you can use the corresponding tap with the given female to identify the pitch of the female thread.
