A: The range of medical oxygen cylinder sizes goes from M-2 to M-250 and includes M-4, M-6, M-7, M-9, M-22, M-24, M-60 and M-122. The diameter sizes range from 2 1/2 inches to 52 inches, and empty weight ranges from 0.7 pounds to 114 pounds.
O2 tanks are extremely heavy (remember they are holding oxygen compressed to over 2000 PSI!). A standard size is called a K tank, and holds about 281 cubic feet, and weighs somewhere around 80 pounds. It isn't a good idea to transport tanks of any kind in a car, first it is dangerous -- if you get into an accident and the tank is punctured, it will become a torpedo, next, because of the weight and size, they can be hell on bad backs and knees.
