Request concerning O-rings

[Mist_Of_Joye]

Imeo, not much, just a thought,

I noticed that the O-rings that we're using for the AVS, when in contact with the liquid, start to leave black traces on the liquid, that then mixes up with the liquid inside the tank.

Of course, it is always recommended to clean AVS parts with water each time we refill the tank, but for those who use a single fill up, over 2 or 3 days, they might have black traces in their liquid, before even finishing that fill up.

Are there types of O-rings that do not leave traces? Blue or white or orange types of O-rings for example? Who cares about the color anyway, since they're hidden now.

I would also like to know the answer to this question. I hate having who-knows-what mixed into my e-liquid. Safety should be our primary concern when vaping and anything to eliminate foreign material in our eliquid is always a good thing.

Indeed, I know that there are specific high-temp and food-safe o-rings that are extremely expensive.
I asked Imeo the same question about these residues and he said that this was not an issue. If it is an issue for you, then I would say you'd probably have to source special o-rings and it might cost you more than the AFS itself to get actual certified ones........

No offense to Imeo, but I can't imagine he or anyone else would know if this was truly bad for your health in any way. I don't think research has been done on vaporizing residual o-ring material. I always had this concern, but decided to discuss it once a post has been started on the topic. If there is any documented health journals out there, please point it out so this topic can be put to rest. I'd hate to stop using the AFS due to health concerns b/c I absolutely love the unit.

I think it's extremely unlikely that there are any problems at all - however, we can't actually prove this for sure unless we have seen heat-safe certificates as well as certification stating that these o-rings won't degrade during use in heated conditions and with these exact chemicals we are using.

This is not going to happen, so we have to make an educated decision as we have with all things vaping related - for example, there are no actual long-term clinical trials on vaping and as yet, no-one can categorically state (with clinical evidence) that it's totally safe to be inhaling food-safe flavourings into our lungs on a regular basis - however, we make an educated choice because we do know it's got to be far safer than smoking but we still can't define (with evidence) how much safer it is.

The o-rings I use are viton and they dont cause problems to health. But because I dont trust anyone that says anything on his site I made new o-rings in a Greek factory. They are made to touch food. They are more sensitive but they are totally safe. All the new units have those o-rings inside. I made a big order of those so they came very cheap to me, almost the same price as the previous ones.

ps....... I dont think that o-rings cause the problem. I think that liquid change its colour because it gets burned inside the atty and then it comes back inside the tank.

Though I'm still waiting for my GGTS to be available for purchase, I tend to agree with Imeo that the black is from previously burnt, recycled liquid and not from the O ring: Being that the O ring material is not painted, but is, in and of itself black, the only way it could impart it's color to the liquid would be through physical deterioration: It would literally have to be dissolving. If the O ring was in the process of dissolving, the decay would be visible: The surface of the O ring would no longer look shiny, but dull. It would feel soft, maybe even sticky (like it's melting). Your fingerprints would remain deeply imbedded on its' surface if squeezed firmly between your thumb and finger. You would also find left over black O ring residue on your finger(s) or rag after rubbing it.

If, on the other hand, the O ring feels firm and still looks smooth and shiny after being rubbed, the odds of it being the source of black juice are at best extremely remote, if not nil.

I'll look when I can.

I cleaned my AFS v2 after reading the start of this thread and before you answered but I did check the O-rings.

In my case, the O-ring around the base of the atomizer was intact and didn't leave any black traces on the hand when rubbed (it's the one getting the most heat).
Cleaning the inside of the Control Ring which has an integrated O-ring in it's middle did give black traces but I can't say for sure if it's due to traces on the thread or from the O-ring (but this O-ring is not in contact with the liquid).

I would tend to agree that the black residues, mostly found inside the AFS at the 8 holes area, are probably due to burned recycled liquid.
Well that sounds like the most logical explanation to me.

Anyway I feel safer now after checking myself.
