thanks for chiming in, xander.
wasn't even thinking about leeching into the o-rings. good point. i would have thought about it later then without knowing which were which,
thrown away my other o-rings after they were all co-mingled.
that's only about half of them. the half that hadn't completely melted down or melted and welded to each other. it all happened in under 30 minutes. probably closer to 15. though, with the help of an ultra-sonic cleaner. they were all tips i'd allowed smokers to use to try a
vape.
