Review: This was a decent purchase for not a lot of money - This worked flawlessly! Flushed my complete AC evaporator, lines and condenser without any problems. No leaks and no other issues. It got the job done!
Review: Easy to use and works well. Rubber nozzle adapters could be stiffer. - 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.

## Features

- 【Suitable for Air-conditioning System Cleaning】AC flush kit is suitable for cleaning all air-conditioning systems and other systems, such as automobile AC pipes, condensers, evaporators, fuel pipes and household refrigerator/AC pipes. When replacing a malfunctioning AC compressor, it is important to ensure all debris in the system is cleared. AC flush kit can help to quickly and efficiently remove old refrigerating oil and debris before replacing the compressor or retrofitting the system.
- 【Pressure Regulating&Relief Valve AC flush kit】AC flush kit is equipped with a pressure relief valve, you can adjust the pressure relief value according to your needs. Just use a hexagon wrench(not included) to tighten the pressure relief valve to increase air pressure, and loosen it to reduce air pressure. When the pressure exceeds 170psi (about 12Kg), the pressure will be automatically released, ensuring your safety. Note: Working pressure do not exceed 150PSI.
- 【Readable Pressure Gauge for Real-time Monitoring&Spray Head】The AC flush kit is equipped with a readable pressure gauge to monitor the pressure in the bottle in real time. Easy to read data and ensure work safety. The AC flush kit is designed to work with any lightweight A/C flushing material. The spray head has a rubber tapered nozzle, which can seal the pipe opening and prevent the solvent from spraying back. The surface of the spray head is electroplated to prevent rust.
- 【Thickened and Leakproof Stainless Steel Bottle&Steel Draft Tube】The bottle is made of upgraded and thickened stainless steel, which is leakproof and resistant to high pressure and corrosion. The AC flush kit adopts a steel tube instead of a plastic one. The plastic tube will fold and cause no flow, while the steel tube allows the liquid to flow out smoothly. (Note: Refrigerants and cleaning fluid are not included)
- 【Hook Design&3.5FT Long Hose】Equipped with a hook that allows you to hang the bottle on the car without holding it all the time. AC flush kit also equipped with a 3.5FT long hose. The max working pressure of the hose is 600PSI and its burst pressure is up to 3000PSI. Easy operation: just fill AC flush canister with lightweight AC flush solvent, connect to your air compressor (not included), and then uses workshop air to pressurize and flush old oil, refrigerant residues and dirt.

## Questions & Answers

**Q: Does the kit come with a case?**
A: No, it comes in a box, but that’s okay it keeps the parts together fine.

**Q: Can you fill the canister with dry nitrogen?**
A: There should be no problem with use of nitrogen instead of air in this unit.

**Q: What type of cleaner do you use with this to clean your AC system? Thank you!!**
A: There is a flush liquid they sell. It's a chemical solvent that smells very much like brake cleaner.  It comes in a quart can. How much you need is dependant on the size of your system.  I used it to flush the lines and evaporator of a car. One quart was plenty.  You flush until it comes out clean. Then blow air through to speed evaporation.

**Q: what size allen wrench**
A: Metric 4MM or Imperial 1/6 inch
