BSP = British Standard Pipe

BSP = British Standard Pipe

BSP is a catch-all for British Standard Pipe. It is usually used as a shortened version of British Standard Pipe Parallel (BSPP). British Standard Pipe Parallel is now designated as G-series of screw threads and defined in ISO-228. British Standard Pipe Parallel (BSPP) has also been defined in the now obsolete BS-2779.

Caution is advised when reading a thread designation labeled BSP because this could be a shortened version of British Standard Pipe Parallel (BSPP) or British Standard Pipe Taper (BSPT). I have seen it both ways.
