Q: What do I need to take to get my tank filled?

A: You should only need to take your tank. The shop should have the correct adapters. However, always take your bottle nut in case something changes.

Q: Liquid or gas fill?

A: Some shops only fill CO2 in a gas phase. For this use you will need to ask for it in a liquid phase. If they are not sure about this ask further or go to a location that is knowledgeable about this question. Our system utilizes the cooling effect of the CO2 when it changes from a liquid to a gas.

Q: Other locations?

A: Some other locations to look at for a fill are- Paintball shops, Dicks Sporting Goods (they fill paintball cylinders), local welding shops, or beverage companies (bottling plants).
