PT is very similar to the BSPT or R. Interestingly, they are interchangeable and compatible. PT male pipe end doesn’t have a 30⁰ flare. That’s why it will not be compatible with BSPP female fittings. But you can always create a leak-proof seal using PTFE tape or any sealant compounds at your disposal.
Likewise, Both styles have the same thread angle, shape, and pitch (threads per inch). However, BSPT threads are tapered and BSPP threads are straight (parallel). 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. In this manner, So instead of having the Standard 55 degree angle on the threads, they changed it to 60. (Yes you have to ask yourself why?). The net result is that whereas the DIN pipe threads are interchangeable with BSP pipe threads, the American NPT pipe threads are not. Just so, WARNING : Never, never try to mate a BSP fitting with an NPT or NPS fitting if the pressure holding capability is at all critical. NPT/NPS and BSP threads are not compatible due to the differences in their thread forms, and not just the fact that most diametrical sizes have a different pitch. Also, JIS Tapered Pipe Thread Type – PT 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.

What's the difference between nps and bsp pipe fittings?
Tapered fittings find use mainly on the ends of pipes, nipples and fitting such as couplings, elbows, and tees. NPS parallel threads need gaskets or O-rings to seal them. BSP stands for “British Standard Pipe” and is the standard in the UK, Europe, Asia, and Australia.
What's the thread angle on a bsp pipe?

BSP stands for British Standard Pipe technical standards. BSP connection includes two types of threads, one is BSPP which can be straight or parallel; the other one is BSPT, which is tapered. The thread pitch and thread angle is the same 55 degree.
What's the difference between npt and bsp pipe threads?
Both NPT and BSP are pipe thread standards for screw threads used on pipes and pipe fittings to seal pipes. With NPT, the peaks and valleys of the threads are flat. In BSP, they are rounded. Secondly, the NPT angle of the thread is 60 degrees and the BSP angle is 55 degrees.

I have found that my Japanese-built injection mold presses have predominantly BSP fittings. While the actual specified outside diameters of American National Pipe differ slightly from those of British Standard Pipe, either thread may reliably be cut onto a pipe of its respective trade size.
What are the different types of bsp pipe?
BSP pipe, Like American National pipe (NPT, NPSM), is designated by trade size, rather than actual diameter, which is approximately equal to the thread's Major Diameter in the table below. There are two types of BSP threads:

What is the difference between bspt and bsp pipe thread?
BSPT thread is used where pressure-tightness is made through the mating of two threads together. International standards require all Female thread is parallel and male thread is tapered. The female thread can also be tapered but this is not common.
What does bsp stand for in pipe thread?
BSP thread form stands for British Standard Pipe and is common in Australia and the commonwealth countries. It is based on trade size rather than actual diameter which can lead to some confusion when measuring ports. Both threads have the same pitch, angle (55 degrees) and shape (rounded peaks and valleys).
