Notes:
* For Dual DOT/ISO Spec Cylinders, the DOT capacities are listed in parenthesis corresponding to DOT rated working pressure at 70 F.
+ These cylinders are also used in liquefied gas service such as CO2 and related mixtures.
- Cylinders are also available in 3/4 NGT and 25E threading.
- Approx. Cylinder weight does not include the weight of neckring, valve or cap.
-10% overfill not allowed for these cylinders
