It depends on your tank's tolerances. Some may fit, but be too thin, or too thick, some O-rings are made of different materials. I find it a bit daunting to keep track of mine, so I just put them back in the packaging, so that I know what I have.

But, if the seal is holding and you are getting a good vape from it, you should have no problems. Glad it's working out, since the tank isn't leaking. It can be a challenge at times finding the right O-ring and I've been fortunate to not have gone through very many although I do try to keep the spares organized, I would not be looking forward to a "hunt for O-rings" on fasttech, or anywhere else.

Sorry but i have to point this out - o rings cannot be changed for other round things like wedding rings, washers or polo mints. Just be aware of this. ;)

Now back to our regular programme;
Once you've been vaping for a while you'll end up with hundreds - perhaps thousands - of assorted o rings which can be used wherever they fit. I've swopped out the originals with slightly thicker or thinner ones in the past and have cured leaking issues that way. Don't assume that because the manufacturer has installed a particular size o ring that it's the correct one - it could be just a case of using up what they've got !!
