Actually, looking at the "operating instructions" for that model it has
a little picture with the end of the BSPP thread labelled "sealing face".
So maybe a squashable washer in there?
Would htat require a special female fitting or are female BSPP threads
always a specific depth with an accurately flat bottom to the hole?

That looks like it's designed to take a pipe cap nut, where the flare in
the pipe does the sealing. Like brakes on a car.
