gas nozzle idea

hey
I was in a hard ware type store a bit a go and I saw some gas nozzles. When I looked closer I Saw inside the tube a piston-like valve and I thought that (when hooked up to a air source) it would make a nice easy-to-make gun. only problem is I didn`t see any psi rating(why would I ,the thing just lets gas go in and out). This has probably been noticed before but I just thought I`d post it.

What kind of gas nozzle was it? What did it go to? Any brand name on it? What type of gas was it used for?

It was just a regular gas nozzle that you`d find at the gas station. didn`t see what brand though, I`ll tell you next time I`m in there,and as far as what type, I don`t think it said. I Didn`t even know there was a different nozzle for different gas.

Are you talking about the kind of nozzle you fill your car up with gasoline? Coming off the gas pump?

There designed for low pressure to help keep fumes down, ozone and health hazard worries and probly more reasons I'm not thinking of/coming to mind.

Most of those a built tough for safety. A broken gas dispensing valve is dangerous. Most fuel gas pumps operate on less than 20 PSI. At high pressure the internal valve which is closed with a spring and sealed by the fuel pressure would be hard to pull open at high pressure.

Commercial gas station nozzles are built to federal safety standards.
Commercial ones have a vapor recovery vent in the USA to reduce VOC emissions.

Home and farm use ones may be lighter duty and may or might not have the auto shut off in them. Either way, they are designed to limit delivery flow rate to prevent fuel spills. This may limit their usefulness on an air cannon.

That's a state/local reg, not a national one. In Indiana the pumps don't have the vapor recovery system on the nozzle.
