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

A must have. Very handy to have around. Not only good for condensation drain lines, but also great for blowing out clogged heating oil line back to the oil tank.

Just what I needed to work with the AC drain cleaner. Would purchase again.

they work as expected

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

thanks

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.

They do the job.

Great product to use in A/C drain line gun to clear the sludge out
