Gas re-filling Gaspatroon C500 Coleman

The C500 gas cartridges are disposable cans that are filled with 70% butane and 30% propane. Each gas can contains 440 grams of gas. These gas cartridges are intended for portable gas appliances from Coleman and other brands with the same threaded connection. By means of this screw connection you can remove the gas cartridge from your gas appliance and use it again later without losing gas thanks to the valve in the gas cartridge.
