Hi Simon, recently I was searching for nozzles
for the epoxy dispensing machine i've been working
on. I found most big hardware stores and even some
supermarkets have a range of plastic tubing and
small nozzles, irrigation type equipment that was
cheap and offered simple on/off valves and couplings
etc. Testing showed it was too small diameter to
suit my epoxy needs, but it WOULD be ideal for
your etchant. :o)
