Sizing advice

BSP thread sizes can be confusing; BSP size is not the same size as the physical thread diameter. When measuring BSP male taper threads the measurement should be taken halfway along the length of the thread. BSP female threads are always parallel along the whole length of the thread – see size guide below.

BSP size                 Diameter of thread

¼”           -               13.1mm Approx.

3/8”         -               16.6mm Approx.

½”           -               21.0mm Approx.
