10 lb CO2 tank with adjustable regulator

New 10 lb CO2 tanks with variable pressure regulator. Regulator is good from 0-150 psi. These are great for a home brew set up as well as, what I use them for, portable air while off road. I use CO2 to air up my tires when I go 4 wheeling. It’s much faster than an air compressor. Tanks are currently empty and can be filled at most welding supply shops and beer breweries. Filling a tank of this size is about $20 and will fill my 37” tires from 10 lbs to 25 lbs about 10 times. I also have tire inflation/ deflation systems and rapid deflation valve stems as well.
