I bought a lot of oxygen tanks and have several for sale for cheap. The are all empty and the hydro date is expired. If you have access to getting medical tanks filled (YOU WILL NEED A Rx) they would be cheap to get hydro tested.
5 Oxygen ME (682L)- $15 each
1 Oxygen D (248L) - $10 each
1 CO2 7.5 Lbs (maybe 5 lb) - $20 each
The white tank is the co2 tank. it is 21" tall with a diameter of 4"
I will ship (you pay) from Columbus OH
