This works better than I expected, in fact, awesome. I applied 80 psi of air pressure to the container and it did an excellent job of flushing out the AC lines. Great value for the price. I believe this could also work for transmission lines and other uses.

Works absolutely as it should, but two small complaints: 1) Without some sort of printed instructions (and there are none) a customer might not realize that they are messing with pressurized air, which can be VERY dangerous. 2) The supplied air fitting’s base diameter was about .006” larger than the fitting on my air hose, so I chucked it into a drill press and filed it down until it fit. Not just everybody would know to do this… Otherwise nicely made and works perfectly.

Just as described

Great quality. Working perfectly.

Muy practico

Headline says it all. No issue using it. You don't need to fill the whole bottle with solvent, only enough for whatever you're cleaning. Meaning, a high pressure line probably only needs a few ounces sprayed through 2 or 3 times to get it clean. A evap core probably more like 8 oz a couple times. Only gripe is the rubber nozzle adapters could have a bit higher durometer. They work, but you need to be mindful of how much pressure you're pushing so they don't blow out, or more accurately, push over the fitting. Cheapo plumbing rubber seals also work well to slide over the nozzle in case you're like me and turn it up to 11 when flushing stuff.

Older system that ruptured a hose. Replaced the broken hose, then used this to flush the system before running vacuum and recharging. Worked perfectly to get old oil/gunk from the system
