Replacement Cartridges

A CO2 cartridge can be used to trigger the Safety Buoy once. Afterwards, the empty CO2 cartridge must be removed, and a new original RESTUBE CO2 cartridge must be inserted.

This is simple, and only takes a few steps. You can view an instruction video here: https://restube.com/blogs/news/how-to-pack-restube-care-and-maintain-correctly

You can also blow up the Safety Buoy manually using the mouth valve. This is a practical option if you are using the Safety Buoy as a swim buoy, or for snorkeling.

Yes, the Safety Buoy may be taken on a plane. Depending on the version, original RESTUBE CO2 cartridges contain 16g or 10.9g CO2 and are under pressure. They are considered a hazardous material in air transport. However, according to the IATA and LBA, passengers may take up to two CO2 cartridges with them in combination with the Safety Buoy. Register RESTUBE CO2 cartridges promptly before your trip begins by phone with the airline and carry a written confirmation from the airline (email) and the green flyer during your trip.

The cartridge is produced in Austria by our long-term partner iSi according to the highest lifejacket standards.

No. Only our RESTUBE cartridges are checked for exactly 10.9g or 16g filling quantity and are compatible with the trigger and have a special alloy for salt water resistance. If other cartridges are used, the Safety Buoy cannot be guaranteed to function properly.

How to get the safety buoy ready for use again is explained in detail in the instructions as well as printed on the buoy and bag. Attention: RESTUBE only guarantees its functionality when used with the original RESTUBE CO2 cartridges.

First any contamination (e.g. sand) must be removed from the Safety Buoy, the trigger and the CO2 cartridge. Then the empty CO2 cartridge is unscrewed from the trigger and disposed of in the recycling center. Then fold in the release lever. Check the new CO2 cartridge for damage before screwing it in and make sure that the puncture cap is closed. Then screw it firmly into the release mechanism.
