This is in no way intended to be a flame as I have used similar tanks with no problems for years. But,
Two weeks ago I bought two Worthington X7 HP 100 steel tanks from my LDS and had them filled with nitrox for my upcoming offshore trip. I dropped them off at my parents' house since we'll be departing from there. This morning as my dad (also a dm) was leaving for work he heard a hiss coming from one of them. He put his ear up to the valve (Thermo) and noticed it came from the valve/neck connection, not from an accidentally opened valve. So I called the LDS who thinks mine may have been among a batch of tanks produced a year or two ago in which they tried a new purple seal between valve and tank which have been shown to be faulty/badly designed.
So I have to get the tanks from my parents place (1 hr away), bring them back to the LDS who said they have replacement seals and will take care of it and get me new fills and VIPs, as the tanks will likely be bled dry.
I was pretty upset since if my dad didn't happen to hear the hiss, this could have happened in the middle of a trip or in the middle of a dive. I figured I'd share so people are aware of this possibility.
