Redrock Unthreaded 16 Gram CO2 Cartridges - 10 Pack

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

Works perfectly

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.

If you’re purchasing this to fit in your AC gun, don’t bother! They don’t fit and Amazon will not let you return it.

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

This product is good but didn't work well for me. Good price, fit my tire inflator. But i have 26.5 x 2.4 mountain bike tires and one of these cartridges could not fill my tire all of the way. I've since ordered 25g cartridges which is a bummer because they are about twice the price. I guess the math works out but not what I planned when I bought into this system, $4 to inflate my tire. Definitely beats walking miles back to car.

Blow out drain lines

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