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

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!

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.

Use with the gallo drain to flush the AC water pipe. Gets the job done and can do on own.

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.

Great price ever where else is half the quantity

Works as described

A must have to reduce service costs,
