While switching over tanks to..
Well while trying to boost my morale tonight after getting a parking ticket, getting to my lab just to find out someone took the power cables from my computer and external hard drive while running, and having a friend dog find my dinner packed in my book bag unzip it and eat thru a ziplock to get my last bbq rib, I tried to switch over the on/offs(for old the manifold style max flo) from my old bottles to the new bottle i got here on AO and realized the SCI nitroduck had a larger threaded hole than the other three bottles. Oddly enough the original bottles were SCI bottles yet the newer SCI had different threads. The threads matched the luxfer nitroduck tho. Was really looking forward to playing with the mags without remoting in air into the max flo but eff it.
