An IBC outlet valve (S60x6 buttress) reaches a 3/4 BSP hose fitting through an S60x6-to-BSP adapter that screws onto the coarse container thread and presents a BSP male. The IBC end seals on a flat gasket; the BSP end on a washer.

S60x6 is a container thread, not a pipe thread. Do not try to thread a BSP fitting straight onto the IBC; the pitch is coarse and unrelated. Use the buttress adapter.
