Just wanted to post this up as it took me some pretty good digging before I found them.  Sun-vapers.com has the food grade silicon O rings for the KangerTech Protank mini, II and III for $1.09 a piece.  This way you wont have to buy 100+ of them from Kanger and pay a ton for shipping.  SV shipping is 3 bucks.  So, two O-rings and shipping is $5.17.  You know you are going to rinse one down the sink.  I had read a few posts about people doing that and I thought "I'll never do that, I will be super careful" then the very next day I rinsed mine down the sink. I thought I was being careful by keeping my thumb over the rim and blocking the ring from coming out as i rinsed it, but what actually happened (I think), is that I was burning some super thick goopy Malty Toffee from Backwoods Brew (92/100 btw) and the o-ring stuck to the glass chamber as I pulled it out to rinse and I didn't notice till it was too late. 
 So, the Protank-2 is out of order till Friday, but still have my v1 so I am good to go.  Hope this helps someone out.  I have enjoyed the crap out of reading posts on this forum and plan on sticking around here a good while.  Happy vaping.  ~CT
