Your cylinder definately had lots of powered al oxide..
And the regulator filter and the internal filter in the rig did not catch the crud before it got to the solenoid?
And I *really* doubt the "wet 02" thing. Even "technical grade 02" (IE welding 02) is generally produced and shipped as a cryogenic liquid, is handled at the gas filling facility as a cryogenic, and is decanted into gas cylinders as HP 02 after it's phase change. There's no measurable water in the gas. It's stored in *steel* cylinders that are never given a visual inspection between the 5 year hydro tests. The *specification* for technical/medical/aviators grades show different water contents, but they are (A) measured in parts per million, and are (B) all generally meeting aviators grade anyhow. I use aviation 02 because I have it, but "Wet 02" is not a realistic concern, even in the third world.
