I just bought a portable compressed air tank, but it only came with a
fitting to blow up tires and such. I was looking for a gun to attach
to it, but all either said they were limited to 30 or 90 PSI, or else
they didn't specify. The tank will hold up to 120 PSI, and the
instructions say only to get attachments that can handle up to 150
Are the guns with no limit mentioned good up to some understood PSI?
The 90 PSI guns warn that they might explode if exposed to higher
pressures, so I'm not inclined to experiment with the unlabeled ones.

Oh, sorry, a blow gun.
<<Anyway, you can always buy a regulator and regulate tank pressure
down to the pressure required by the tool you're using. >>
I thought about that, but I was concerned about accidentally changing
the setting and having the gun blow up in my face.
Most home compressors max out at about 135 psi, a few go to 150. Most
products of that sort have burst strength of 1000 psi or more. We've been
using them in my industry for 35 years and none has ever broken. Even if it
did breaks, it would likely crack, rather than blow apart.
<<It keep it from over pressurizing if you push the nozzle against
something. It will be able to take the line pressure from any home
And now, just for your amusement, I did something ignorant. I found
this white stuff wrapped around the male fitting, so I unpeeled it. I
figured it was something to protect the fitting during travel. <sigh>
Now I know it was the teflon tape. I'll have to buy some more.
A lot of them don't have those vents, but like someone else said, they
probably will not burst under pressure. I like the adjustable ones.
What kind of gun? Paint gun? A tank without a
compressor isn't good for much. You can inflate
tires and you can put quite a few nails through a
small gun before you need to add pressure. You
have to look at the PSI limit and the air flow,
e.g., 50 psi 5.7 cfm. Most compressors pump the
tank up to a certain amount and also have an
adjustable pressure limiter on the outlet which
you adjust for the tool you use. Paint guns are
usually fairly low and pressurized guns will blow
the paint container apart if the max pressure is

Just a blow gun. I plan to mainly use it for cleaning right now, so I
figure it will last a while at that. I'll get a compressor in the
future, but I have to keep my purchases in line with my time available
to learn to use them properly.
Even if the metal did crack, there's not enough volume inside the
typical blow gun to generate an "explosion" . It would just leak.
Now, if the tank burst, parts of it would probably go through the
