The British standard pipe thread (BSP thread) is a family of standard A list of 15 thread sizes are defined by the standards, ranging from 1/16 to 6.

BSP threads are identified with letters each of which represents the type of thread and their associated standards 1:. G: external and internal parallel (ISO 228, DIN 259) - BSPP R: external taper (ISO 7, EN 10226, BS 21, JIS B 0203) - BSPT Rp: Internal parallel (ISO 7-1, EN 10226) - BSPT Rc: internal taper (ISO 7) - BSPT Rs: external parallel (BS 21) - BSPT- Obsolete

1) Measure the O.D (Outer diameter) of the BSP thread. 2) Take the O.D measurement in inches and subtract 1/4 (.25″). For example, a BSP 

You can cross-reference the bore size on the following chart with thread pitch and threads per inch to find your desired size and its related specs. BSPT-tech.

Using the table below we can see that a thread measuring 1/2" is actually a 1/4" BSP thread. Similarly, a thread that measures 1" is actually a 3/4" BSP
