For hydrotesting, the company doing the testing puts the tank inside a big sealed drum full of water and pressurizes the tank to an extremely high test pressure specific to the tank. they measure the amount of water displaced and if it's over a certain percentage, the tank fails.

Scuba tanks require a visual inspection inside the tank YEARLY, along with hydrotesting every so many years. Some scuba shops have hydrotesting capabilities, but most places where paintballers get their tanks filled cannot.

Depending on where you get the hydrotesting done, cost can range from $10 at a local tester, to $25 + shipping to and from an out of state company.

alright I know I'm necro-posting, and on a sticky worse yet, but I need this question anwsered

I have a HPA tank with a hydro test birth/date of March 2003. its a Luxfer tank with a DOT-E of 10915

so I have a 5-year hydro test, unfortunatly my pro-shop took a look at my tank and said that he couldn't find a confirmed DOT site that specifically stated that I had a 5 year hydro date... needless to say after driving 30 minutes to get to the store I was a little frustrated, so to avoid this, is there any sites out there that is run by the DOT people who can confirm it is indeed a 5 year hydro date?

help if ya can I'd appreciate it

I have a new question along these lines: what happens when an exemption expires? I have two DOT-E8096 cylinders, and that exemption ended in June 2007 (see exemption E08096). Does anyone know if I can continue to use the cylinders, since they were manufactured under that exemption and haven't reached the end of their services lives? Or can I only use them until they're empty (per 49 CFR 180.205 paragraph c) since they no longer conform to an active category 3E exemption?

I have two 9oz tanks and a 14oz tank that the local welding supply company that fills them says never need hydro testing because they are steel. Is this true? Both were filled many times after the 5 year hydro date expired on them because of this.

Weigel21, it depends on what code is stamped on them. You can usually do a Google search on the first part of the line beginning with "DOT..." if you don't mind taking someone's word for what the law says. At least for the 9oz tanks, I believe they're almost always exempt from hydro-testing (category 3E) due to their small size. If you don't mind doing a little reading, the DOT haz-mat regulations are usually pretty explicit, if byzantine. The relevant sections for us are 178.xxx (category definitions, manufacture) and 180.205 (re-testing).

3E-8096 tanks can no longer be used. The exemption expired and was not renewed, which means the tanks no longer have a valid exemption status on them.

I read this thread and didn't really understand it or im reading it wrong or looking at my tank wrong. So maybe you can help me.

It is a 20oz CO2 tank.

TOP: DOT-3AL1800 BL 191602
BOTTOM: TC-3ALM124 CLIFF DIV05 (some symbol here) 02 1.25 CO2

Thanks.
