    Caliper –

    A caliper is a useful tool that measures the outside diameter of a male thread and inside diameter of a female thread. Using a caliper will give you the most accurate and precise measurements, but a straight steel ruler is a good alternative. However, if you think you’ll be using one quite often, here’s a digital caliperwe found on Amazon for a reasonable price.

    Pitch Gauge –

    A pitch gauge measures the threads per inch. For metric threads, this tool measures the distance between the threads. If you’re looking to buy a thread pitch gauge, Grainger has a pretty good selection.

    Step 1 – Male Threads v. Female Threads

    First, you’ll need to identify whether the thread type is male or female. Take a look at where the threads are located. If they’re on the outside of the thread, it’s a male thread. If they’re on the inside of the thread, it’s a female thread. The gender of the thread doesn’t necessarily have an impact on the functionality of the thread. It simply serves as a way to distinguish between the two connections.

    Step 2 – Tapered Threads v. Parallel Threads

    Next, determine if the thread is tapered or parallel. Tapered threads become narrower as they extend outward while parallel threads remain the same diameter. Sometimes this characteristic can be determined through visual inspection, but if not a caliper can come in handy. Use the caliper to measure the first, fourth, and final full thread. If the measurements are all the same, then it’s parallel. If the measurements decrease in size, then it’s tapered. NPT/NPTF, BSPT, and Metric Tapered are e...

    This thread type is most commonly used in North America. You’ll recognize it by its tapered outer and inner diameter which is self-sealing. When torqued the flanks of the threads compress against each other forming a leak-tight seal. However, it is still recommended to use PTFE tape or another sealant compound to guarantee a completely leak-tight s...

    This is a standard thread type that has been adopted internationally for interconnecting and sealing pipe ends. You’ll find it used all throughout Europe. There are two types of BSP threads, BSPP and BSPT. BSPP refers to parallel or straight threads. Meanwhile, BSPT refers to tapered threads. Sometimes BSPP threads are referred to as G threads and ...

    PT thread type is identical and interchangeable with BSPT thread type. However, since the male PT thread does not have a 30-degree flare, it will not mate with the BSPP female swivel with conical seat. Also, we recommended using thread sealant with PT threads to ensure a leak-free seal. *O.D. = Outside Diameter I.D. = Inside Diameter Go to top
