Well im running out of options. I took the o2 tank into airgas and asked if I could get it filled with industrial grade oxygen. He said they had no way of filling it because the valve is a cga870 not a 540 like most industrial tanks have. They wont exchange it for anything but if I wanted to buy a new tank from them they would be happy to set me up, for about 120 bucks.
Life is like a plate of chitlins, everythings fine till you realize what your eating.
