For use an HPA tanks, which o-ring would be the better fit? What's the pros and cons of each material?
I've decided to order a bunch but I want to order the right ones.

Just goto WalMart or ****s, or Sports Authority and get the 10 pack they have. All you really need is one o-ring if you have an On/off. The only time I've ever broken an o-ring is with my shocktech on/off because it doesn't really work too well.

Buna-N's are cheaper, and work fine.
