Rebreather World - View Single Post - What cylinder characteristics are preferred

IMHO for salt water you need hot-dip galvanized or aluminum. "Spray" galv or "hardcoated" (e.g. Faber) just doesn't cut it IMHO.

What I'd love is the Faber "parkerized" inside and the PST "hot dip" outside. Best of both worlds.

BUT - while I know this runs counter to the grain here that I see above, I'd like my cylinders able to be filled "full" off a 2400 psi supply bottle. I'm skittish around O2 beyond 3k. Other industrial and medical users are too - scuba seems to be the only place where that's pretty much ignored. Every now and then an OC user gets a "surprise" with a deco bottle and reg - so far as I know there's only been one incident with a Rebreather, but it burned a boat to the waterline when it happened.

The counter-argument is of course for travel, especially internationally.....

So for local stuff I'd like a ~20cf LP bottle at a reasonable price with decent balance (not too outrageously head-heavy.) If that's lighter than a HP bottle then maybe that works ok for travel too....
