BES Ltd., British Standard Pipe Thread Identification Chart.
BSP – This is an abbreviation used for British Standard Pipe threads, and the size refers to the nominal bore (or internal diameter) of the steel pipe the thread was originally designed for, not the diameter of the actual thread. Please measure your maximum (or major) thread diameter in millimetres and use the chart below to identify the BSP size you need.
