Thanks. Did you get that somewhere on the website that I just missed it or is this your personal words of wisdom?
No, it's not on the site. The site is after all a little bit confused.
If you can bear with me for one more questions, what exactly does it mean that a regulator is "oxygen cleaned"?
What Jim (& kat) said. Plus they guts of the reg are cleaned with a detergent like Simple Green to remove any combustibles such as particulate or hydrocarbon contaminants.
