The Carbon Dioxide (CO₂) cylinder has an internal pressure rating range from 700-900 psi. At room temperature the pressure is about 845 psi. Certain precautions are therefore advised when handling. To avoid bursting, do not expose to heat beyond 140 degrees F or store in direct sunlight. To avoid possible freezer burn (after activating) do not remove frozen container for several seconds. For best performance results, keep cylinders at room temperature prior to use. FACT: cold weather exposure greatly reduces internal pressure. Example: At 32° F pressure is at 491 psi. At 2° F pressure is 302 psi. At minus 20° pressure is only 200 psi. So if used, out of doors, on a cold day, keep them in your chest pocket, at body temperature, until ready for use.

Transportation Notice: CO₂ shipments are usually made by UPS ground under the ORM-D consumer commodity code. Note: Air shipments containing CO₂ can be made, however, there is an extra charge for this service.

Federal Express® will accept CO₂ as dangerous goods (UN 1013) and deliver them anywhere in the U.S. and to certain foreign countries. However, some countries will not allow direct Fed Ex deliveries of compressed gas, through customs. To avoid this problem, check with your local Fed Ex office or call our office to see if we can ship it to you! Note: CO₂ is banned from being sent through the U.S. and international postal system.

Airport to Airport Service: In the event that Fed Ex does not offer direct service of dangerous goods to your area, there is another way. We can ship CO₂ to a large airport in your country but you will be responsible for customs clearance. This usually involves hiring a customer’s broker to clear the goods. Airport to airport service is less costly than regular service but a bit slower. This alternative is not feasible unless you are importing large amounts of product and have a full understanding with customs procedures. Before ordering, consult your local Fed Ex or customs office about CO₂.

Warning: Like all other pressurized containers, CO₂ is restricted from being carried in your luggage on passenger air flights. To avoid confiscation and delays, we advise you to check with your airline for the proper procedure or ship it ahead by Fed Ex. We have distributors in Singapore, London, Australia and Canada. If you can’t find the threaded CO₂ in your area, call us, perhaps we can help you locate a supplier. Use the above illustration for comparison.

Note: The threaded type CO₂ charge is not to be confused with the non threaded, small neck, BB gun or paint ball gun type that is found in hobby shops. Due to its unique application, the threaded type is found in very few consumer outlets. However, our warehouse maintains an adequate supply with inexpensive prices and can ship on short notice.

How Safe is CO₂? Next to compressed air, CO₂ is the safest form of propulsion you could ask for. However, because the CO₂ containers are pressurized, they are classified as dangerous goods when sent by air and restricted material when sent by ground. As you may already know, CO₂ is widely used in fire extinguishers and produces the bubbles in carbonated drinks. The threaded type CO₂ is also used by defense contractors as a component in missile guidance and coolant systems. The origin of the CO₂ cylinder is said to date back to 1885 and was first used as a disposable refill for a soda siphon device in Europe.
