[PSUBS-MAILIST] 02 tank

[Alan via Personal_Submersibles]

Rick,
I would approach the O2 supplier that you consider you will be getting
most of your O2 from, & ask them the question.
It would be no use cleaning yourself if they want some sort of certificate.
I was advised by the local Padi dive centre to go with steel tanks, & I got them 
to clean them & the first stage regulator. They were specific about what 
1st stage regulators they could O2 clean. They put a nice big official looking
oxygen sticker on the bottle & made me do an emergeny O2 providers course.
   The local gas supplier on the other hand was a bit clueless as to requirements
& would only fill with a medical fitting.

Probably dependent on the manufacturer and retailer, the latter usually supplying newly purchased cylinders with an initial visual inspection sticker for recreational divers. With the prevalence of nitrox mixtures in recreational diving, it is becoming more commonplace to supply conformant cylinders, but check with your supplier. Oxygen cleaning is something you can do yourself, simply by using hydrocarbon free detergents, rebuild kits or o-rings which are O2 compatible (i.e. Viton), and O2 compatible lubricants such as Christolube.
