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

My first one of these saved my butt on the trail today. 5 stars it is!

good price, fast service

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!

Seems to work as expected

I used these for testing my Onyx M-16 life vest. I wanted to keep the original equipment manufacturer OEM cylinder for actual emergency use, but these cylinders are PERFECT for testing my equipment to make sure that my life vest is free from holes and that the actuator works. Worth every penny! I swap one of these cylinders in for testing, go out in the lake and tried this so that I knew what to expect when I pull the cord in case of emergency. Once back on land, I dried out my life vest, repacked it and installed the OEM cartridge (and re-arming pin). For this purpose (testing) these cylinders were completely indistinguishable from OEM at a fraction of the price of OEM.

Seem to be quality spare standard CO2 cannisters for my bike pump.

These seem like good solid cartridges. They attached cleanly to the inflator, with even smooth threads. I used it to top up a couple of somewhat flat bike tires (and there is still gas in the cartridge). They sure get cold when you fill the tires, though :-) - it's nice to have a cover to protect your hands (there's not much choice on that, the laws of physics rule).

Nice for travel bike bag to repair flats.

They are what they are. Haven’t used them yet but they be in the saddle bag until required

I hope I'll vever have to use it.

Good

Ok

5 star if it was cheaper
