A lot of HPA tanks dont specify what their cylinder specification is. for HPA you HAVE to check the exemption number to find the specification.


Most of the steel cylinders are 3AA, 5 year hydro, unlimited life. There are some 3HT steel tanks, which are 3yr hydro, 15yr life.

I woudl say that well over 90% of paintball shops CANNOT do the hydrotesting.

towards the top of the thread I posted a link to the DOT approved hydrotesters list.

You can check that list for local companies in your area that can do the hydrotesting.
Make sure that it specifies HIGH PRESSURE TESTING beside the companies name.. a LOT of places can do low pressure testing, which is under 600psi for DOT specs.

Or, you can check online for a hydrotesting company.. typically costs run around $25 per tank.

MY tank has a silver square with "rehydrotest before" and then a spot for numbers, but you cant read it!! I think this is kind of dumb.ok here are the number on my tank they are around the top in two rows
top row: DOT-3AL 1800 D628450
BOTTOM ROW:M5659 05A05 P 20 OZ CO2 TC-3ALM 124
I am assuming that the 1800 is the maximum operating pressure and the D628450 is the serial number, so does anyone have anyidea what the other numbers mean?

DOT-3AL is the hazmat spec for the tank.
1800 is the service pressure.
D628450 is the serial number of the tank.
M5659 is the manufacturer code.
05A05 is the manufacture date: 05/05
P 20 OZ CO2 is the fill weight
TC-3ALM is the Transportation Canada spec for the tank.

- (Rehydrotest Before 10-2010)

- This cylinder must be rehydrotested every (5) years by a qualified retester.

i have some old tanks, not sure when they were made because i bought one used and the other one refurbished :( They are both Brass Eagle 9 oz. tanks

the numbers on one is DOT-3E1800 TC-3EM124 M9001 09 lA18 01 119

the other is DOT-3E1800 TC-3EM1124 M9001 1/lA18/03 A74 -CANADA-

no clue on what these numbers mean, tried to figure it out with other examples.

thanks.

The portion I have in bold is all you need to know really. Both tanks are listed as DOT 3E, which is hydro exempt.

on an old tank I would be worried about the threads giveing out on the top of the tank where the brass Valve is seated, I do not think a Hydro test could help predict the likelyhood of that

one day I was shooting at someone in a game of woodsball, and the Velocity bolt sprung out and hit me in the mask, the threads had become week, and came off, leaveing just a regular bore where the the threads used to be

nothin a tap and die didnt fix, but just a thought that passes through my head sometimes when I look at that 9ounce tank I have that is going on 5 years old. How long before the threads give out on that? maybe they wont because they dont have the weight of a bolt slamming against it every time you pull the trigger, but I just read somewhere on this forum that the only paintball related deaths were caused by the valve comeing out of the tank, and the tank propelling itself into somebody

What's involved in Hydro testing? I am buying a scuba tank and will the place that fill that be able to hydro test it?
-Thanks
