16g CO2 Cartridges

These work just as well as the expensive ones from the bike shop and cost less than half as much. Now I can carry 3 or 4 on my all day rides and not be afraid to give one to a stranded stranger :) I have a tiny Serfas inflator and I have had no problem getting them threaded and inflating a tube with them.

I bought these for a CO2 powered growler with keg tap. Upon receiving I immediately tested one cartridge, in a sense wasting it, but I wanted to make sure it did not shoot out any oil since it could end up in my beer. There was no oil so I can safely assume that these are indeed food safe. 30 should last me a long time and this was one of the best prices I found with positive reviews for threaded food safe CO2.

Works as expected. NOTE: make sure you use something on the outside of the cartridge while using them. I make that mistake and the VERY cold temps burned my hand.

fits great. makes my home brew taste great.

Used as bicycle accessories, to aid in filling a tire instead of using a hand pump.Small enough to carry two on the road bike.

I got these with the hopes that they would provide a cheap alternative to the expensive Fluval Co2 20g, low and behold they fit just fine! If you are not used to handling Co2 cartridges, like I was the first 3, you may lose quite a bit until you get the regulator on. My advice: finger tighten until contact is made with the needle, then turn quickly to puncture and don't stop until the hissing ceases. My first only lasted 2 days but now I can get about 4-5 which is due to user error. My hopes that i can get a week between cartridges with skillful practice.

As advertised and one of the best deals ive found for these threaded cartridges. They work great for my bike tire inflation tool. I carry three or four incase I dont get the patch right on the first try, and this is an economical (hopefully) lifetime supply. Fully recommended.

So far these are fine but if you are using these for cycling the outside of the cartridges will oxidize over time. I keep my spares kit in a small pouch that I keep in my jersey because I like to keep my bike free of extraneous items. I recently had to open the bag and found the two cartridges were covered in oxidation. This probably wont effect how they work but the oxidation could possibly make the seal between the cartridge and the valve has a less than perfect seal. How important is that? I don't know so that's why I reviewed it with a "it's okay" 3 stars. The price is good.
