Redrock Unthreaded 16 Gram CO2 Cartridges - 10 Pack

Hard to find non-threaded and food quality rated, but there fit both requirements. Used for a pressurized growler able to keep beer or ciders fresh for weeks.

I use them to blow plugs from my a/c drain lines. It normally only takes one to do the job. You will need the hose gun thing but it’s easy to use. Do hold the trigger and use the entire cartridge and you should be able to hear the plug blow out. It’s so much better than paying the AC guy to come do the same thing

Use in a in my A/C Condensation Blow out system to clean lines. I always have success with them. Good Product.

Like so many others have said, these cartridges do not fit the RedRock Gallo drain gun. The neck diameter is larger and won't fit the gun.

I would get threaded next time.

Blow out drain lines

I ride my road bike all year long, these are a must because you’re bound to get a flat tire at some time.

Bought these for my ukeg 128 since they were better priced compare to others I found. It seems to be hit-and-miss with them for my ukegs. Worked fine a couple of times, but I also wasted a few of them due to leaks within the ukeg cap/sleeve. I thought the issue was with the cap itself and the gaskets, so I replaced all the gaskets and even tried a different cap, but still would have leaks. I have never had that issue with different cartridges. These seem to be slightly shorter than the ones the ukeg came with (just barely, maybe by a millimeter) and the sizing chart suggest they should be compatible but unfortunately I haven't had much luck. After buying them, I found a couple of other reviews suggesting the same issue with them specifically for use in the ukeg. Good product and price, but if unfortunately they didn't work as intended for my ukegs.
