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.


How can Restube help me?

The most effective way to immediately contain critical situations in the water is to have additional buoyancy right next to you. Restube is so small that you can always have it with you and it doesn’t affect your mobility in the water. But if you want buoyancy, all you need to do is pull the trigger. You can also pass the buoy on to someone else or wave it to draw attention to yourself.

Why do I need Restube?

Restube is so small and robust that you can always carry it with you. With a pull on the trigger you have a lift for yourself or others in seconds! Restube is not a substitute for a life jacket or armbands – because it is intended for all those areas of use on the water where it was previously not possible to carry safety with you, because there was nothing that was so compact and light before inflating. Restube is similar to a Swiss Army knife: you are prepared for a wide variety of situations.

How does Restube work?

When you need a boost for yourself or others, pull the trigger. The sealed CO2 cartridge is pierced and fills the buoy in seconds. If you lean over the Restube buoy, it will lift your head out of the water. You can also wave the buoy to attract attention.

Can I use Restube more than once?

Yes, by replacing the CO2 cartridge, Restube is immediately ready for use again.
