Tank O2 cleaning.

[Zodixo]

I have a few questions.

1st, where can I purchase glass beads for rolling the tanks. Will normal marbles work? (AL 80s )

2nd. Valves. There is so many conflicted information regarding what valves can be used for pp blending o2, what are you guys doing? Are you only using the pure oxygen rated valves, even on a twinset used for trimix?

Check local machine shops for suppliers of tumbling media.

Any brass valve/manifold properly cleaned, with viton orings and o2 safe lube is ok for pp blending.

I have less white quartz river pebbles in my garden

What makes tanks "O2 clean" is the washing process, not the tumbling media.

Otherwise, what Still Kicking wrote.

I used an ultrasonic machine for cleaning my valves.

Why do your aluminum tanks need tumbling? That is not in itself a part of the O2 cleaning process.

I like to add some tumbling media to scrub the tank. Not extended tumble like tumbling per se.

Thank you all for the input.

So I will use oxygen rated valves on my deco tanks that will have high o2, and then just properly clean and use correct o-rings for others that pp blending will be done with 100% o2 but used with less than 50%.

And of course glass tumble tanks with some simple green, (cant find the simple green crystal here)

I use airsoft bbs for washing. Adds a bit of agitation.

SG is fine.
