Do you know what, I totally forgot about that
I was just typing and remembered what luvverly stuff TI was. I just plain forgot it loves a little O2 fire.
Which is why all these posh TI regs say 'Not for Nitox use'

. How dumb of me.
Maybe I'll stick with SS.
As an aside, does anyone know just what conditions are required for an O2/TI fire to get going (I'm not planning to find out).
Cheers (Embarrassed as hell for such a donut mistake)
Even stainless isn't necessarily O2 compatible.
