16g CO2 Cartridges

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.

fits great. makes my home brew taste great.

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

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.

I use these to cool my drinks in the summer since using them to air up a tire seems like a waste since in 24 hours its all gone from the inner tube like some sorta sadistic bi polar rider. Just insert the product into a spray apparatus. This will release the cold stream of air which freeze the metal spray to an icy metal cube of cold. This will turn your hot summer drink into a cold refreshing party hit for all the guesst.

I always purchase my CO2 in bulk... I ride both Mountain and Road and usually carry at least 3 of them with me... I can not count the number of times that I have stopped to help a rider with a flat.... IT makes it so easy and I keep the spent CO2 for recycling... For the bicycle riders:One other note... Buying the "name brand" CO2 cartridges are worthless... CO2 is CO2 so you are paying for the advertising and the label on the cartridge...

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.

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.
