Tank Valve

[akdeepdiver]

If you want, I (my shop) will do the overhaul to include replacing all needed parts/orings/washers, replacement of burst disk, and O2 clean for $15 plus shipping. Shoot me a email at tanktest@gmail.com or message me here.

If you have a good relationship with your shop and the tech have them do the work ask to hang out when they do it so you can learn what they do and look for.

Did exactly this. Was super informative.
Thanks for all the suggestions!

I just noticed that two of my tank valves (DIN) had some dark-gray hardened residue in them. Does anyone know what this is? Is it anything to be concerned about?

Looks like it might be some activated charcoal dust from the compressor filter system.

 

[oceancurrent]

So, nothing to be concerned about?

I don't know about breathing it but they make you swallow it as an antidote to absorb certain kinds of ingested poison

I would also think carbon from a filter.

If those are tanks used for PP blending that is not good. Carbon can burn vigorously in an oxygen atmosphere.

My guess is the whole tank looks like that.
