Threaded CO2 Cartridges 16g (20 Pack) CO2 Cartridges for CO2 Tire Inflator

I bought about 4 batches of these cannisters. I use 1 each time I replace the propane tank which helps to keep the Mosquito Magnet reliable.

I use it for a growler, works very well.

These 16g CO2 cartridges work perfectly for my small kegging setup. I use them to carbonate and dispense small batches of cider or session meads, and they’ve been consistent every time. My only complaint is that they run out pretty quickly, so if you’re doing more frequent kegging, you’ll need to stock up or go a different route for carbonating beverages. But for small, occasional, and portable use, they’re very convenient and get the job done.

Not exactly 16g of CO2?!? I expected better from a well known name brand. So far only one of the 15 cartridges I have used has delivered 16 grams of gas. I used a precision jewler's scale to measure the full cartridge and then the empty. Each time the difference revealed that the cartridges delivered only 14.2 grams to 15.4 grams of gas. That is up to 12% less than adverstized!! That sucks and ICO should really look into their quality control. Hopefully they are not purposefully underfilling their cartridges!?!? That would be a sad way to make some $s, by cheating their customers. Otherwise the cartridges are OK, I guess.
