Choosing the right option
Check the nut thread (BSPP, a parallel thread) and the hose tail size separately, because the reducing sizes pair a larger nut with a smaller tail. The nut screws onto a male BSP thread. Order the matching rubber washer (KRW series) for the straight sizes if you need a spare.
