Four Seasons 69991 Dura II Flush Solvent - 25 oz

Good product that is recommended by all your compressor manufacturers, did the trick and back running ice cold air once again after a compressor failure.

Work seasonally on auto HVAC and this flush agent is a must for removing years of oil varnish, crud and whatnot from lines, hoses and components. Gets everything super clean for re-oiling and recharge. Leaves no residue, evaporates quickly (read as need ventilation). Just responsibly dispose of the refuse and you are all good.

I used the 59024 flush gun and flushed out each component as directed. Worked well but I had to get another bottle of this locally because I needed just a bit more to do my truck. If I was a bit more careful and conservative in the beginning one can might of worked. I spilled a bit when pouring into the flush gun.

The picture is misleading. This is the best flush on the market, however the liquid comes in a container about the size of a quart, but contains only 700ml/25Fl Oz. Be sure you order enough!

Great stuff. Cleaned nice and dried quick. Every site I read urged using this product as being the only one you need. I would agree. My system had been filed with that green dye. Air is ICE COLD on 90+ days.

Used this to flush my A/C lines while installing a new A/C compressor on my Dodge Ram 2500. It's a must to get your lines cleaned after a internal compressor fail. This stuff really gets the debris and old oil out of the system very well. I would recommend it.

This stuff works, but make sure you use it all. If you leave some in the can, it will eventually evaporate, it does not matter if you make sure the bottle is tightly closed/sealed. Also, it's kind of expensive compared to other A/C flushes. I don't know how well the other brands work. The price has remained the same for the last 10 years or so. So, if you factor in inflation, the selling price is a better deal than years ago.

Its AC Flush I can only work one way! Fours Seasons Compressor kit was installed and the the system was flushed before installing it... R134 AC system is blowing 36 degrees at the vents so i would say it did it's job. Thank you! Great Product!

Seems expensive for the quantity. I did work great though, I didn't have enough to flush all my components.
