RedRock 16 Gram Unthreaded CO2 Cartridges for Gallo Drain Gun HVAC Drain Line Cleaner Tool (30 Pack)

They work as advertised. That’s all I really ask of a product. I will buy this item again when I run out of this supply. That might be a while, though, since I only use about 2 per year.

Great but I don’t think it has as much pressure as the one I bought at Academy used for a pellet gun. However the CO2 from Academy were smaller and it had an air leak when punctured in the drain line gun.

As advertised. Works. Well packed. Good communication. Would order again.

Easy to use. Price is good.

Perfect!

These fit into the AC Drain line guns, good to keep some on hand

I have a Rectorseal Lineshot drain cleaner to clear out AC condensate drain lines. But a dozen cartridges cost about what this brand charges for a box of 30. So gave them a try. They are a bit shorter, but they work fine. You have to screw the handle on the drain gun down all the way to get it to puncture, but it does fully puncture and dispense good. You could also drop a washer into the bottom of the handle to raise the cartridge up more if it didn’t screw down enough to puncture, but mine screwed in enough to puncture as-is. CO2 dispenses quickly and completely, and blows out line as good as original cartridges. See pictures. Original Rectorseal cartridge has the label on it, this product has no label. Punctures good, width is the same (drops into handle perfectly), nipple is shorter but diameter of nipple is the same. Will buy again when box of 30 runs out.

Im using these as tire inflators. OMG great value! If you have unthreaded co2 inflators for your bike these are a little bigger but they work!
