Insurance won’t approve my oxygen tank...sigh feeling helpless in General Board Posted September 25, 2019 Hang in there Kat.. I'm sorry to hear that about your 02. I myself use welding 02 for similar reasons. Any chance you live in a populated area? It helps because on Craigslist and letgo people sell 02 tanks all the time. You might want to take a look.. some tanks are not too heavy.. the other thing you could try is just taking a ride to the welding/gas supplier near you because it's not uncommon for ch people to be use these places.. the supplier near me is very familiar with the condition. They might be more then willing to set you up with something. Refilling tanks is not expensive.. good luck. If you need any help don't be scared to ask..
