Scuba Cylinder Chart
The chart illustrated here lists over 35 scuba cylinders that are currently available in the United States. Care has been taken in its accuracy, though it is possible that some have not been listed and for this we apologize. Specifications have been provided by the manufacturers and are believed to be accurate. This chart if for general reference only, check the manufacturerer's specific data sheet for the tank you purchase for exact data. This chart gives some useful data about scuba tanks, but is missing two items about each tank that would be more useful. This would be the actual physical tank volume, sometimes called "water volume," and the manufacturer's part numbers. We hope to add this information in the future.
