I've got some loose, Luis. I'll measure them at the weekend if no-one answers sooner.
cheers

My understanding is that BSP parallel thread fittings (which is what the petrol taps thread/union type are) have a 60 degree cone angle. I have measured an image of a solder on nipple in Autocad and the angle of the sealing faces (marked in your photo) was 60 degrees.

Cheers

Alan and Johnny, thanks you very much!

Now that I know the angle I have to turning the nipple, it's time to use the lathe!

Thank you Luis for the pictures. I've acquired a Myford from the widow of an old friend and late in life am learning turning. A simple job supported by a few pictures which explain all are encouraging.
Regards from MikeN.

Luis,

I would advise making the nipple from brass. It is easier to solder on to the pipe and being softer than steel, the taper seals more easily.

don't make the fitting a tight fit on the pipe or the solder will not flow in to the fitting
