These PVC one-piece ball valves are manufactured to industrial standards and have BSP (female) threaded ends.
Imperial pipe and fittings are sized by their nominal bore or approximate inside diameter: please note that imperial pipe threads (British Standard Pipe) do not have direct correlation between the stated pipe or fitting size and the diameter of its thread.
Approximate sizes are as follows:
- BSP 1/2" - 21.0mm (approximate thread diameter)
- BSP 3/4" - 26.4mm (approximate thread diameter)
- BSP 1" - 33.2mm (approximate thread diameter)
- BSP 1¼" - 41.9mm (approximate thread diameter)
- BSP 1½" - 47.8mm (approximate thread diameter)
