Recommendations for use

1. Screw the cartridge into the nozzle to pierce the cartridge so it's ready to use.
2. Hold the cartridge by the plastic cover to protect your hands from the cartridge cooling down while inflating.
3. Place the nozzle straight over the valve and push firmly to insert the valve into the nozzle in order to release the air.

Puncture tips

With your other hand, we recommend pushing on the outside of the tyre at the valve to prevent the valve from going into the tyre when you push the inflation nozzle down.


The CO2 cartridge is composted of 100% steel and can therefore be recycled.
