How do I know when a CO2 tanks "expires"?
 

How can I tell what date the tank is good until? (aka - when does it need a new barotest?)
Thanks

Stamp on the side of the bottle, usually they highlight them will different paint.

month/year stamp

for the stamp, is the month and year separated by a triangular A?
Here is the two lines stamped on my tank:

TC-3ALM124 T11.3KG S971865F ALS
DOT-3AL1800 U356865 LUXFEWR 07^97 20#CO2 TW24.9

The portion that has 07^97 is separated by a unique triangular A and if this is the expiry date, I'm assuming the tank's expired.

Do you know where can I get the tank a new barotest?

I dont recall a symbol, but that looks like the expiry date.

DBC Marine will do the Hydrotest, then refill the canister.

FWIW, it might not be an expiry date. I thought it was the date that it was last hydrostat tested, which is good for 5 years. Although in this case, it's expired since it's past 5 years.

Sorry I thought that was what he was asking was the expiry for the hydro test.
