## Description

High-quality 20 cu ft steel oxygen cylinder with CGA 540 valve. Ships empty! Heavy-duty construction with thick walls and a durable painted finish. The tank has great low-temperature delivery. Guaranteed date of manufacture or hydro test within 12 months. DOT approved. A doctor's prescription is required to fill with medical oxygen. Seek the advice of a physician if you have questions about the proper use of medical oxygen. Please be sure to use a regulator that fits the cylinder valve, and that is correct for your application of use. Product note: compressed gas cylinders can be dangerous if used improperly. Please be careful, know the correct procedures for use, and exercise caution when connecting and using any compressed gas device.

Review: DOT Rated! - I was pleasantly surprised to find this cylinder was DOT rated. Many of the cheap online ones aren't. This may not sound like a big deal, but it is. Like 99.999% of us, you're probably going to swap this out at a supply house, or have it filled, if your local gas supplier does their own filling. If it doesn't have a DOT rating, most places will not fill or swap the bottle & you're stuck with an expensive paperweight.
Review: Nice! - Nice Tank!
