## Description

New 40 cu ft steel oxygen cylinder with pre-installed CGA540 valve. Perfect for oxy-acetylene welding and cutting, torch work, metal fabrication, industrial processes, and medical use. Oxygen is widely used in welding applications, typically added in small amounts (2-5%) to argon to enhance arc stability and improve metal wetting. Portable at 24 lbs with 7" diameter for mobile welding and job site work. The CGA540 valve is designed specifically for oxygen service and must be used only with oxygen-compatible regulators and equipment. Heavy-duty steel construction with green painted finish, DOT approved. Ships empty per shipping regulations - fill at certified compressed gas supplier. Medical oxygen requires doctor's prescription. Never use with oil or grease. Refillable for long-term oxygen delivery.

Review: Great tank - Very nice quality tank
Review: What They Say is Right On The Money - The best aspect of this sale was the little green slip in the box, with all sorts of telephone numbers to call and websites to access if the Buyer encounters difficulty. In my case I've tried two or three times to get outside vendor oxygen cylinders filled and have been told "no way" by my gas vendor. So I needed to get a 40-pounder and this Seller specifically says "DOT," etc., in the ad word. I took it in to the gas vendor and he did his best to disqualify me for the fourth time. (Please note my gas vendor COULD NOT come up with a new cylinder even though their store is coast-to-coast.) But, try as he might, he could not refuse to fill this time, because this tank had ALL the requisite stamped legends, dates, approvals, and whatever is needed to qualify a tank. PERIOD. When this seller says they will support the sale, they mean they will step up to the plate for their customers.

### ⭐⭐⭐⭐⭐ Heavy duty yet light weight for medium jobs
*by S***N on September 4, 2019*

This is excellent quality, brand new condition and best of all it is heavy duty yet light weight, so I can weld all I want in my smaller garage for long periods of time, which is just what I needed. I'll be purchasing again for sure.
