Every part of the Peaty's CO2 inflator kit have been agonised on - from the straight line inflator head to the high quality CO2 cartridge sleeve.

Why Use CO2 Inflators Over Hand Pump

If the hole in your tyre is so big that sealant can’t seal it, your tyre will lose all air pressure and, most of the time, the tyre bead will pop off the bead seat on the rim, creating air gaps all the way around the tyre bead. As anyone who has set up tubeless tyres before will know, getting enough air into the tyre to pop the tyre bead back onto this bead seat isn’t easy, even when you’re in the comfort of your home workshop, never mind out on the trail with a group of impatient mates - or worse - mid race.

A lot of people carry mini hand pumps with them, and they’re great for re-inflating small amounts on the trail after slight pressure loss, but you’d need forearms like popeye to re-seat your tyre with one! Without doubt, the quickest and easiest way to get you back riding while out on the trail is with a co2 inflator. Not only do they get you back up and riding again much quicker than a hand pump, they are much smaller and easy to carry with you on your ride.

What Pressure Will A 16g or 25g CO2 Canister Inflate My Tyre To?

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:

Wheel size	16G	25G
29” x 2.4	21psi	34psi
29” x 2.1	30PSI	45psi
27” x 2.8	13PSI	25psi
27.5” x 2.4	25PSI	40psi
26” x 2.4	27psi	41psi
Fat Tyre	-	7psi
700c 28c	80psi	120psi
700c 23c	125psi	Two tyres at 70psi

Straight Line Is The Fastest Line

Straight line, compact design enables faster airflow for rapid inflation, and creates less stress on your tubeless valves when you’re using it. From flat to inflated in less than 10 seconds!

Designed For Durability

Made from CNC’d 6061 aluminium, and with a patent-pending valve design, the details of Peaty's inflator heads have been agonised on - from the exact rubber compound of the O-rings to the awesome Chris King anodized colours.

No Gloves, No Problem

Peaty's applied the same level of detail and quality in making a high quality CO2 cartridge sleeve. Far from a cheap strip of neoprene, our freeze protector sleeve is made from temperature resistant silicone and has a unique closed base to stop your hand from freezing to the cartridge, no matter how you hold it - even without wearing gloves.

Weight (CO2 Inflator head + CO2 25g): 138.2g
What's in the box (MTB): 2 x 25g CO2 cartridges, 1 x inflator head, 1 x closed base freeze protector sleeve
What's in the box (Road): 2 x 16g CO2 cartridges, 1 x inflator head, 1 x closed base freeze protector sleeve

Instructions:

Remove the valve cap and loosen the valve core. Check the valve is clear by pressing down the loose valve core. You should hear air flowing through the valve
Cover the CO2 cartridge with the closed-base freeze protector sleeve provided
Screw the CO2 cartridge fully into the inflator head. You may hear a small hiss when the cartridge is successfully pierced. If not, give the valve a quick press and you should hear gas 'tsssst' out
Press the head over the valve and push straight down firmly to discharge the cartridge and inflate the tyre to your desired pressure. Releasing the inflator head will stop the flow
Once the tyre is inflated, remove the inflator, re-tighten the valve core and re-apply the valve cap
