not having much luck finding someone to fill my e size medical oxygen tank. medical wont touch it without rx, matheson gas or praxair wont touch it either. I think the tank is too big for a firehouse cascade system anyway.
I got the runaround yesterday trying to find one of our many local medical supply places willing to fill my O2 tank with no luck. I ended up going to a local Class D airport with a good selection of FBO's and had it filled there. $30. I am tempted to just buy a tank from the local welding supply store and a fill/transfer hose and be done with it.
