I was looking for an alternative to Aluminum O2 cylinders of which I have a good number of. I had one carbon fiber O2 tank that I got really lucky on because most people didn’t really understand what it was because the seller wasn’t sure himself. I got it for pennies on the dollar.
I was on Ebay looking for O2 equipment and ran across these scuba / fireman cylinders. They were just gently used air cylinders in the factory boxes. I bought 4 for $50 apiece with free shipping. I removed the scuba regulators. I found stainless steel high pressure fittings to adapt the scuba threads (**0.875-14 UNF) to the CGA870 threads ( .750-16 UNF) O2 fitting. I can now use the standard CGA 870 O2 valve to thread into the adapter and the adapter into the tank threads. I also found some rubber scuba tank boots to put on the tanks because the bottom of the tanks are round for strength. These boots are made so that the cylinders can stand up on their own which makes them so much easier to use. These tanks bought new will run you $400 to $500 apiece. I now have lighter carbon fiber O2 tanks over all aluminum tanks that will last me for most of the day using my pulse oximeter with them. I have less than $100 total in each tank. I cleaned all of the fittings, cylinders and threads with acetone to make sure that they were fully clean and no residue was left in any tank. I am estatic with these carbon fiber tanks being so much lighter than the same size alumium tanks. Since I fill all of my own O2 tanks it now won’t cost me anything to fill and use these tanks.
Here are a few of my tanks that I use for backup or when I am away from home.
that is awesome. i dindt know you were using the actual 02 tanks… I have a concentrator at home im plugged into all the time… then i have a oxygo system i use for mobility, but neither use tanks. i only have one tall tank, and its only for emergency use only.
I had an Inogen 4 portable concentrator. it wasn’t worth it for me to only get 3 or 4 hours at most out of it. The batteries were outrageously priced and yoi went through 1 or 2 batteries a year. Then you have to replace the beds inside the portable concentrator. Me carrying one small tank and a pulse conservator I can go fo 8 or 9 hours before replacing the tank. The tanks that you were looking at will last me a full day without replacing it. I a basically am self contained. I can do everything myself and I don’t rely on a medical service or home health to provide any O2 supplies.
wow. that self contained thing sounds good to me… all my oxy stuff is “rental” and my oxygo portable only lasts 4.25 hours at 2liters an hour which is what im at. like when i go to the gathering i have to shut it off usually when im not moving around much, and not exherting myself to conserve battery, and i also bring the charger and plug up some while im there just sitting for an hour or so. it really sucks. the batteries are 300+ each, and i am NOT going to buy a battery for something i do not own, and the rental group wont give me a secondary battery to use either no matter how much i complain… so it is what it is at this point. Could i get the metal tanks and the roll around trolly to pull with it sure… but i really dont want to have that many tanks… cause none last as long as yours do.
Keep an eye on that site, you may find some in larger sizes for even cheaper. Or even better items. I’ve bought some lockable, rolling pelican cases that were for CPAP machines on that site for $50 shipped.
