BSP threads have a 55° included angle and have rounded peaks and valleys (this is a Whitworth thread form). Here are the actual thread dimension data for BSPP and BSPT threads. The major diameter is a bit larger smaller than the actual OD of the pipe, and the minor diameter should be very close to what you would measure inside the

Parallel threads: also called straight threads. These threads have a constant diameter, 

BSPT & BSPP Threads Dimensions. Thread size refers to the nominal bore of the pipe. Subtract approx. 1/4″ (6mm) from thread diameter measurement for nominal pipe size. Pitch is Threads

systems. The BSP thread is offered in a straight (parallel) form known as BSPP and a tapered form known as BSPT. These threads feature a 55° flank angle. Fittings in this section with male BSPP threads use a primary sealing method of an O-ring and retaining ring, as shown in Fig. G5. Fig. G5 — O-Ring with Retaining Ring

The main difference between NPT and BSP threads is that the thread angle in NPT threads is 60 degrees while that of BSP pipes is 55 degrees. BSP threads are usually straight/parallel while NPT threads are usually tapered. If the threads are the same size then it is BSP whereas if the first thread is small (in diameter) that the last then it

These threads come in two versions: parallel (BSPP), and tapered (BSPT). The thread 1) Measure the O.D (outer diameter) of the BSP thread.

Likewise, pipe thread can be parallel (e.g., BSPP). For pipe thread, determine the size by comparing it with a nominal size profile, as shown in Figure 1 (a useful tip - pipe sizes up to 2" nominal size can be determined by measuring the actual outside diameter, subtracting ¼" then rounding-off).

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
