CO2 Tyre Inflator kit

The pressure you will be able to get from a 16g or 25g CO2 canister will heavily depend on your wheel size, tyre width, tyre depth and rim design (a rim with a big dip in the middle will create more volume to fill than a shallow dipped rim).

With so many variables it’s impossible for us to guarantee exactly what pressure you’ll achieve in your particular setup, but we’ve put together a table of wheel / tyre sizes below to demonstrate what pressures you’re likely to achieve with either 16g or 25g cartridges.

Recommended Size

When CO2 is highly compressed (870psi to be precise!) it becomes liquid. The process of turning liquid CO2 back into a gas is called an exothermic reaction. This means that the CO2 has to steal energy from somewhere else in order for it to turn into a gas - in this case it steals heat from the CO2 cartridge, the inflator head - anything it can get its energetic little mitts on! This is why it’s so important to always use the closed base freeze protector sleeve, so it doesn’t steal heat from your hands and give you freeze burns!

If your valve stem has any moisture on the outside of it then this moisture can freeze solid when the CO2 gas is released. This moisture could then freeze to the o-ring on the inflator head and make it feel stuck, but fear not, just simply twist it anti-clockwise a few times as if you’re unscrewing a thread (to break the seal of the ice) and it should pull straight off again.

If your valve stem has a restricted airflow (from a sealant blockage or has a partly closed or broken valve stem) this can cause a build up of freezing CO2 liquid or gas in the valve head which can - sometimes - cause the inflator head to freeze up (especially when inflating in a downwards position).

This can also happen if there is residual water inside the inflator mechanism.

Don’t panic, if this does happen, simply wait a few minutes for the ice to melt and the mechanism will move and blow gas freely again.

It is important to check your tubeless valves for any blockages as this will massively reduce C02 air flow into your tyre, and can lead to the gas spurting out of the inflator head. A quick clean out of your tubeless valve will fix this. Simply remove your valve core and unblock the valve by poking a small object through, something like a small allen key will do the job. Put your valve core back in and re-inflate your tyre.

CO2 blasts out of the inflator head at around -50 degrees, so it will freeze any sealant that it comes into close contact with however, since our Tubeless Sealant formula is a water-based formula (which means the latex is suspended in water rather than chemicals) it will soon defrost and performance won’t be affected.

If you are running another brand of Tubeless Sealant then please check with the manufacturer's guidelines to see if it is compatible with CO2 inflators before using.

Single use, yes … but fully recyclable. Just pop these in with your metal recycling and they’ll be made into something shiny and new again in no time!

Yes, you breathe it out all the time. In one day, the average person breathes out around 500 litres of CO2 gas – which amounts to around 1kg in mass. By releasing 16g of CO2 then, you’ll be releasing the equivalent of around 20mins of standard human exhaling.

CO2 is also commonly used for propelling fire extinguishers and inflating life jackets but most importantly carbonating beer.

A CO2 inflator head alone weighs 15.2g

A CO2 inflator head with a full 16g CO2 cartridge weights 83.8g

A CO2 inflator head with a full 25g CO2 cartridge weights 138.2g

Each CO2 inflator head is dual sealed to provide an excellent, durable seal. After popping a CO2 cartridge you can expect to lose only around 0.5g per month.

Yes, but they won’t have our unique fully enclosed sleeves so don’t blame us if you get frost burn.

1. Do not use with CO2 cartridges over 25g.
2. If using multiple CO2 cartridges in one session, wait 30 seconds between each cartridge to prevent ice build-up in the inflator head.
3. Ensure the inflator head is fully threaded onto the CO2 cartridge before use. Failure to secure tightly will cause improper operation and may cause injury.
4. Test the cartridge is fully pierced before use by briefly pressing the head down onto a hard, temperature resistant surface and ensure a high flow of CO2 being discharged from the inflator head
5. Do not remove the CO2 cartridge until it is fully discharged.
6. Check CO2 gas is fully discharged after each use by pushing head several times against a hard temperature-resistant surface
7. Point away from yourself and others while using
8. Do not use if any part is cracked or damaged
9. Do not expose the CO2 cartridge to heat, store at temperatures above 49oC (120oF), or store in enclosed vehicles
10. Make sure to wear gloves when inflating to avoid injury
11. The inflator head and CO2 cartridge will become very cold / frosty when the CO2 gas is expelled. Do not unscrew the used cartridge until it has warmed enough to touch
12. Keep out of reach of children
