Fcers,

need some help on an (imaginary?) issue. i use an o-ring like that in the pic below to make the operation air tight.

if the o-ring is heated and close to the air path, am i being anal in asking myself whether it's safe ie will it off-gas or something?

For those who do use o-rings, would you use silicone from china

this seems a lot more quality but if it's viton. is it as safe as silicon?

Anyone with o-ring experience could chime in?

Even if your glass part gets so hot that you start to hurt when you touch it you are still fine with that silicone o-ring. Same goes for viton. I use silicone or viton o-rings at work for applications that get much hotter than your gong will ever get with vaping. You should be safe.

I don't think it gets enough heat where you are placing it...
natural farmer, that's a very diplomatic way of telling me that i'm being anal. :)

To tell you the truth, I have no idea where our o-rings come from. They are bought from an european supplier, but I never checked where they are made. Don't really care as I am only useing them for work, not my vapes.

If you're no sure, you could heat one on a hotplate or something, to say 200°C, and take a whiff.

Or look for signs of discoloration or loosing flexibility and stuff. But like I said, I bet you are safe on these kind of temps.
