Not all CO2 Cartridges are a like and we highly recommend only using the Restube spare cartridges.

We know you can find some cheap cartridge alternatives on Amazon, so before you do that, understand this... The Restube cartridges are made of a high quality galvanized steel, so there is there will be no rust or corrosion. In fact, the galvanized steel we use is 20x more higher strength than the life jacket industry standard.

Cheap Cartridge Warning

They frequently do not come fully loaded with 16g, which could be an issue with the Restube to fill. They are made thicker, making it harder to pull the trigger, and with many times use, it will actually wear down the trigger pin. It is common for a cheap cartridge to put on double seals so they won’t leak but this can cause it not to work or have trigger malfunction.

Make It Last

Rinse your Restube device after each contact with salt water they can last for a long time. We also recommend to check the weight after a longer period of time. Each cartridges comes with a label indicating the individual weight. They manufacturer needs to indicate a “best before” date so they are stamped to say 5 years.
