Can anyone tell me what this o-ring is for? My Billow V2 Nano seems to be working fine without it?

It goes on the top of the barrel that screws over my coils and makes contact with the top of the inside of the chimney.

I was rinsing my Nano off last night and accidentally lost it down the drain. I checked the bag of o-rings that came with my tank but the only one that's even close to fitting is just a few mm too big, almost like it's the barrel o-ring for the full size Billow V2.

Anyway, I've been using it without this o-ring and it hasn't leaked, gurgled, or anything. As far as I know, the top of the barrel doesn't even come into contact with any e-liquid.

it's to create a seal. I lost mine and the Billow started leaking almost immediately when tipped to the side. You have a baggie of spares in your box. I'd recommend replacing it. And the full size billow and the nano use the same orings...

I've been tilting it to the side trying to get it to leak or at least gurgle all morning...nothing. I even left the whole thing upside down with a full tank while I was sleeping last night...nothing.

None of the o-rings fit. I got the Billow 3 months ago or so and I've never opened the spare o-ring baggie until now. So if there is supposed to be a spare, mine didn't come with one.

Okay, but they don't just put orings in random places for no reason, so just remember that. Keeping it upside down wont do anything, lay it on its side for ten minutes if you want to test for leaks. And I had one extra spare in my baggie, it is a tiny bit bigger but you push it into the groove and it fits. I'd give it a shot..
