British Standard Pipe (BSP) is a set of technical standards for screw threads that has been adopted internationally for interconnecting and sealing pipes and fittings by mating an external thread with an internal ( ) thread.It has been adopted as standard in plum and pipe fitting, except in North America, where NPT and related threads are used.

NPT fittings will have threads with a 60 degree spread while BSP threads will have a 55 degree spread. A manual thread pitch gauge. Use this chart to easily compare NPT and BSP. How to Measure Threads Whether you're working with NPT or BSP fittings, you'll typically be able to tell the difference between tapered and straight connections.

There are two types of BSP Thread available. One is Parallel threads or we can say Straight threads. The second one is the Taper Thread. BSP is BRITISH STANDARD PIPE THREAD- Also known as Whitworth 55° Thread Form. BSPT is BRITISH STANDARD PIPE TAPER THREAD - Thread form per AS 1722.1, BS 21, ISO 7.

The following quotation from the obituary from The Times of 24 January 1887 to Sir Joseph Whitworth (1803–1887) shows. The British Standard Fine (BSF) standard has the same thread angle as the BSW but has a finer thread pitch and smaller thread depth. This is more like the modern "mechanical" screw and was used for fine machinery and steel bolts.

NPTF, BSPT and BSPP measure 1/4" larger than their actual size. For example, a 1/4" NPTF, BSPT or BSPP will actually measure 1/2" on the O. D. of the threads.
