    These threads always seem to come down to cave divers saying "We don't have any problems despite filling it like this over the years," while people outside of cave country saying "You shouldn't overfill tanks, it is dangerous."

    Which is right? That is for each person to decide, but I have a set of LP85s in my trunk that are at 3,800psi the last time I checked them.

    I am still waiting for a picture of a chrome moly vanadium lp steel cylinder that failed catastrophically. I always think of these and the threaded brass valve that sits on top. Now, which is the weaker metal?

    BTW, Chrome moly vanadium is what the Army specs for gun barrels.

    Great, thanks for chiming in guys, there is a lot of misinformation out there. Especially on this topic, for some reason.

    Forrest was kind enough to give me a pair of steel 72s from 1969 (I was 12). While my daughters have used and like them, I have not yet. But I think they will be a nice set for Jug!

    Someone will show you a picture. I have even seen one in person. It was a rusty mess. Nothing I would put shop air pressure in.

    I believe that to be true. And never is a long time.
