Mystery oil in food grade n2 tank?

No never even considered a rebuild on the regulator. What black oil could potentially be coming from there?

Well that’s the thing nitrogen isn’t completely inert, close but not completely. Argon on the other hand is.

It’s nitrogen dioxides or oxides.
Shitty heaters, chillers and Any equipment can cause that even those n2 is inert.

It could have easily grabbed gunk from the tank and pushed it in. Shouldn’t happen with food grade, but here we are.

N2 is not a primary solvent. I made a system that n2 was a tertiarty property where it cool and also causers pressures in system but it wouldn’t act as you think.

it’s a way to rule out the source of contamination

if it’s in the regulator, then it’s probably coming from the tank or a component in the reg breaking down

if it’s downstream it might be hoses wearing out or something that got sucked in somewhere

I agree with trying to find where it came from. But in what way would a teflon hose break down from n2? the regulator is a possibility but even at that, it sux if they break, I thought theyd last 30 years in a shop environment.

I don’t see any check valves on the n2 system, could bleed butane back in and cause wear

mechanical damage is a possibility too. maybe whoever threaded the bottles didn’t feel like cleaning all the machine oil out

its kinda cheap= blast it into a tank after cleaning and see whats up from there. I dont think n2 mystery oil is a standard thing. put some into a collection with a exhauust valve open a bit and see if it deposits anything.

That would be my guess at this point
