Has anyone found composite tanks with smaller diameters that are less than 18inches tall?
I follow the industry pretty closely and don't believe there are any for sale
in the USA/Canada.
I would suggest the aluminum ones with a float gauge. The price
is similar, they last longer, and the only disadvantage is that they are very slightly heavier. Compare the full weights of similar sized cylinders, since they're all light enough to be easy to handle when empty.
The 10# aluminum cylinders are 15.9" high and 10.3" diameter. They fit most lockers, and weigh 19.7# full. I have a similar steel
one, they're a nice size and very easy to handle.
For comparison, as noted above, the total weight of a full 10# capacity aluminum is 19.7#, and the total weight of a full 11# capacity composite is 19.6#.
Or, the full aluminum 20# weighs 34.2#, while the full 17# composite weighs 27.3#

That sort of torque requirement is typical.
