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

works all the time. primarily used it for seating tubeless tire.

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!

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.

These o2 cartridges were used for our life vest. Worked well.

good value

Great for my needs and love the price.

They are for an inflator I keep on my dualsport motorcycle. I can't say if they work good and hopefully will never need to find out. I just hope they do work good if I ever do need them.

I use them to easily Infllate tires and to remove stuck balls inMuzzle loading rifles
