On the following pages you will find a selection of our Powerjet / Metaljet kits. Some of these may not be usable in your country. Depending on the regulations in the respective countries, the gas cylinders can either be filled by the user himself or must be filled by an approved filling station. Therefore, please observe the regulations applicable in your country for filling gas cylinders. All gas bottles are delivered empty. Also check which gas cartridge connection is used in your country. In Europe, gas cartridges with a 7/16″ thread are mainly used, whereas the 1″ connection is common on the US market.
