Sorry for the post but thought this might be best as some good people here


Bought some air tools the other day and have just noticed the air line inlet
size says 1/4 NPT now the only snap couplings that I can find are all
BSP taper or parallel !!!!! What is one to do and is it the same as 1/4 BSP
is this usual for air tools as I have always fitted 1/4 BSP couplings
without any problems ???

BSP Taper and NPT fittings *are* different, but I think that in the smaller
sizes they are close enough to each other to be interchangeable.

I hope that has sorted the problem. Just to make you smile, apparently a
diving magazine recently had a tool kit offer which contained pliers,
cutters etc and two adjustable spanners, one imperial and one metric. It
would appear that there is nothing more irritating underwater than putting
an adjustable spanner onto a nut only to find it doesn't fit because the nut
is metric!

gist of this!)

Don't recall that, and I read most of them (diving magazines that is).
The April editions will be out by now.

Most diving tool kits consist of hammers and cold chisels.
People who are into the dismantling side of diving usually haven't got
time for anything as sophisticated as a spanner.

Ha Ha, thanks but anyone know why air tools which need a coupling on them
have a NPT thread when the couplings them selves have a BSP thread
???????????

NPT is the american pipe thread - US market/made tools and fittings are
all NPT.
