Redrock Unthreaded 16 Gram CO2 Cartridges - 10 Pack

fits my inflator nice unit

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

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.

Bought these to save a few bucks/finally ran out of old ones & am in attic blowing out AC for the summer. These DO NOT fit a Gallo gun! Therefore, they are worthless. Barely far enough to puncture/then can't tighten & simply leak out. Had to put gun in vise to get cartridge off. Never happened before & been doing this for years. DON'T BUY if that's your purpose.

I have a Home Craft Nostalgia kegerator & these cartridges are just slightly too short to seal, so once punctured it releases all the gas. After 4 tries I was able to use some rubber washers & tape to make a good seal, but its not worth the effort.

Works perfectly

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