BSP Taper threads

[rick]

Looking for advice on suitability of a BSP fitting.

My need is to fit a 1" BSP male thread into a clearance hole is a
thin(ish) plate and fix it there with a nut either side of the plate
One of these :

My question is the Male threads are BSPT (not BSPP)
Will a standard 1" BSP nut hold on a 1" BSP tapered thread.

I have no experience of Taper threads so unsure.

This does not have to be a water tight seal, I can use PTFE is required,
my only concern is the physical fitting. (it's blowing low pressure
air through fitting)

If you must stay with that fitting then it depends on how thick the
plate is IMHO. Try screwing on a thin 1" nut as far as you can, insert
male thread into plate and apply another nut. Sounds feasible to me but
I may be wrong as it depends also on what is hanging off the female thread.

Yes. It might be a bit loose it is fitted at the thinner end, but it
will not come off.
