Might be worth asking about, too, if you supplier doesn't routinely do aviators. The whole thing with medical O2 is pretty wierd, and even the FDA doesn't seem to really have a handle on it. It's the labeling that makes it medical - so if the plant puts the same thing as they'd put in a medical O2 tank into another tank, and doesn't label it medical, then it isn't medical. But most suppliers are dubious enough about selling to divers that they aren't about to go very far out of their way to help them. I say the hell with it and use the welding stuff. It's a heck of a lot easier. According to my dealer it's also purer - welding O2 is at least 99.5% pure, but the FDA only requires med O2 to be 99%. -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
