WORTHINGTON CYLINDER 333251 Cylinder, Red Pack of 4

Works great for small operations

Small canisters one seems light on its weight but it got the job done

The oxygen bottle in this kit is 1.4oz which is good for about 2 to 3 minutes with a very small flame and that's if your lucky. I've had some last 60 seconds after getting the flame right. The red canister empties very quickly so I decided to cut it open to find out what's going on here and there is tiny tank inside what looks like a tank similar in size to the mapp gas bottle. The mapp gas bottle on the other hand Is good for quite some time. I've gotten hours of time out of the mapp gas bottle. Whoever's idea it was to hide the tiny tank inside the large red canister should be prosecuted for fraud, oh wait that would be 'Benzomatic'. Don't fall for this companies scam!
