Gas Thread info needed

Hi everyone,



Does anyone know the thread size on an LPG gas torch?



What I want is a gas hose that goes 3/8 BSP to 3/8 BSP, but BOC sold me a hose that has 3/8 BSP one end and a thread that fits a torch the other end.



I either need to return the hose or get an adapter to go from the female torch thread to female 3/8 BSP and I cannot find an answer to an adaper because I don't know the thread, or where to find a suitable hose.



This is for my home made propane gas burner.



Thanks



Eric
