Can someone please tell me a reliable source to find orings for drippers/tank. I've been looking for like the entire year I've been vaping and yet to find a place. I know fast tech had em but by the time I found out about them they were closing. I've found one company that would sell me replacements, and they charged me 15 dollars for two rubber o rings. I mean I know that don't last forever, so where do I get some more? A couple of my drippers are leaking like the titanic?
