Hi,
I just bought a used #5 co2 tank recently. Here is what was stamped on the side:
86 G
1 (some symbol) 04
DOT-3AA1800 M8004 REE 19:5 TC-3AAM138
B15457 TW11.4LB

Can some one help me to decipher it?
Thanks

There should be an actual date stamped directly on the cylinder. Near the top of the cylinder.

According to the info above, I believe the stamp date when it was last hydro tested is 1/04 (Jan 2004).

Typically it's a 5 year retest. So the next retest will have to be sometime before Jan. 2009. When they retest it, they'll put a new date on it right underneath the old date.
