16g CO2 Cartridges

Used for a one gallon growler with a co2 charge cap. The calendars worked perfectly and a spare could easily be taken along if away from home.

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.

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've been a cyclist for 30 years writing between 100 and 150 miles a week. Flats are inevitable CO2 is a quick recovery. However, they can be real expensive, this product The Price is Right and functions as good as any on the market. Bill

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.

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.

So I'm on my second order of these threaded cartridges I use for mountain biking. Might have had 1 or 2 dead out of the first batch but still the purchase has brought my total spending commitment to CO2 way way down from buying in the sporting good or other brick and mortar stores. I suspect it could be a good buy for anyone using them for similar purposes.
