i don't think it's the o ring problem......cuz i have the newest madbull propane adapter (with the silicon oil container)....so the O-ring in the propane won't catch the valve stem in the adapter....
one thing i realized is that those 2 tanks of propane that "leaks", i tried to put silicon oil on the propane tank itself rather than the silicon oil entrance on the adapter....
i'm gonna buy 3 more bottles and see how thing turns out....
