I'm on actionvillage, looking for tanks. Now they have a section for CO2 tanks and Nitrogen tanks. Can the nitrogen tanks be filled with high pressure air AND nitrogen, or does action village just not sell HPA tanks?

Nitro tanks can be filled with air.

N2 and HPA tanks are the same thing.

Cool. thanks for the replies.

One more question... What exactly is hydro testing? I know it has to be done every certain number of years, but I bought a 20oz tank a few weeks ago, and it doesnt seem to have a date written on it.

n2 makes up most of the air so just regular compressed air is mostly nitrogen anyway.

Hydro testing is done on tanks to test the integrity of the tank. HPA tanks need to be hydro'd every 5 years.

Do a quick search here on hydro, I think there is a good post about it. I can't remember if it was on the new boards or the old one.

If you don't find anything I can post up some more info on it.
