CXWXC 16g / 25g Threaded CO2 Cartridges or CO2 Inflator for Bike Tires - Cartridge for CO2 Inflator with Threaded Connection, CO2 Pump for Road and Mountain Bikes

we purchase this to re-arm our onxy m16 life jacket. Tested and I confirm that it works exactly good as the OEM one, which is $16 per cartridge

They work. Best of all, not a ripoff like the PRO BIKE TOOL cartridges.

I bought these for my planted aquarium’s first co2 system, and they fit perfectly! I recommend using 1 bubble per second or the cartridge will run out in less than 6 hours, I’m already on my second one and it hasn’t even been a full day.. but after figuring it out I’m confident that it will last for a little over two weeks!The metal is high quality and sturdy, the threads are as they should be. My plants seem to be responding to this co2 already! I bought this as an emergency replacement after my first co2 cartridge leaked everywhere, and I personally would not buy again as it’s not worth it in the long run.. but this is great if you need co2 on a budge!

Perfect for any cyclist. Light. Not bothersome. The “ get me home “ cartridge. It’s a must.

Good quality cylinders. They hold up to my off road abuse and deliver when needed.

Perfect size for inflating a 29 x 2.40 MBT to 40 PSI

I have ordered these before and will continue to order these as needed.

They are a good quality. I ended up contacting Amazon because I found them cheaper somewhere else. Amazon refunded me my money and told me to keep them. Thank you, Amazon.
