3.5 oz CO2 tank!!!

[Lucky]

This is a bit of an odd one, where in the system is it being used.

It's not being used, it's still in the shop

As there's no need to test these bottles, in theory it would be ok to use even if it's dot. But you could say as it's dot it can't be used here.

I doubt you'll find a ruling on this, and as they are probably all dot anyway, i would guess it's ok.

Not all bottles are covered by the testing excemption.

It has to have a specific stamp on it DOT-E7737-1800. This stamp only covers the bottle and not the bottle valve.

There is no legal need to test bottles that are stamped this way but I contacted a well known bottle testing company about 2 green 7oz bottles that came with my phantoms and they recommend not using a CO2 bottle more than 10 years old.

That's one thing we haven't got into, the lifespan of these bottles. There is talk within the testing fraternity about increasing the 15 year lifespan on certain bottles, and there are already 20 year bottles out there.

I'm working on 'If in doubt don't use it'. So my old colour matched bottles are now for display only.
H-Pac will test CO2 bottles but it costs more than buying a new bottle.

On a side note Wevo do 2 inch tanks with 3000psi air valves.
