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.

I would get threaded next time.

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.

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.

Easy to use and clear the ac drain when used with their tool
