Wanting to get this filled, but can't find the volume of it.

[Layman]

Does anyone remember the volume one the aluminium tanks like this? 9oz steel for size.

I would be frightened to have that pressurized and near me....

It's weight and storable volume should be stamped into it.

2" cylinders are exempt and it's in pretty good shape. The only think stamped on it is the 1800psi working pressure.

Is this a paintball tank, or a fire safety thing?

[Layman]

Paintball tank, but will be used on a fish tank.

[punkncat]

Using for CO2 injection on a plant tank?

[Layman]

Yes, I run co2 on it and the plants are happy

[Bleeds]

2"x 2' tanks are exempt IF the manufacturer is still paying on their exemption stamps. Luckily Cliff Div's E7737 is good to go.

This is good to know. I had never read that part of the exemption, thanks!

That looks like an old 10oz Thermo valve tank, if I were a betting man. My old 10oz had a hugh on/off handwheel though. Kind of like this one.

Yes, this has the "upgraded" knurled knob. My other has the traditional valve wheel. Thanks, 10oz looks right compared to the 4oz aluminum tank.

It's a 10oz. Had one just like it back in the day.
