Goplus A/C AC Flush Kit, Heavy-duty & Safety Air Conditioner System Flush Gun Kit, Car Cleaning Tool Kit for R134 R12 R22 R410 R404, AC Flushing Kit

I just replaced pretty much my entire AC system in my 2007 ram 2500 5.9L cummins. I've never done AC work like this in a car. I replaced the compressor, orifice tube, drier/accumulator, and condenser. I used this kit to flush the evaporator and the 2 hard lines being reused. It is a nice kit for the money, no complaints really. Easy to use, etc. I used Supercool Flash Flush (solvent based, not oil based - leaves no residue). This worked great for me, the only issue was it uses WAY more flush fluid than I anticipated. I bought two 32 oz bottles thinking thatd be plenty, and I used the entire first bottle in about 10 seconds! I ended up screening/filtering and reusing much of it so I could flush each part multiple times. The first flush on my evaporator came out dirty/grey so I discarded it, but everything else came out clear so I filtered reused it. Just something to keep in mind. I think blew compressed air through the parts to dry them out. The flush fluid I used evaporated very quickly (I spilled some on the shop floor) and didn't leave any residue, I highly recommend it also.

This was invaluable for doing my car a/c system. Using the proper fluid to clean out the lines the a/c works perfectly and will freeze you out. would recommend to anyone..

Great tool, great price. Be sure to use teflon tape when you put it together for a leak free experience. I use it mostly to pressurize an AC system and check for leaks. The fittings are all I use most of the time.

This flush kit is nicer than I expected for the cost. Fit and finish is good quality and it's easy to assemble. The tank was clean but I still ran some flush solvent through it before using it on my AC system. This is good practice and particularly important if you're flushing either the evaporator or condenser. The Goplus is easy to use. The main thing is to make certain the tip is properly inserted, and you have a good seal, before you squeeze the trigger. If you do otherwise you'll "flush" a lot more than you intended. I used it with highly volatile solvent and had no problem with it degrading the rubber tip. I also was impressed that a spare rubber tip and O-ring were included. There was also a quick-fit air adapter included. Unfortunately, the adapter included isn't the one most DIYers will need. If you have a compressor you likely have one laying around anyway. So.......bottom line; good product at a good price.

It's pretty straight forward. Install the air fitting that works for your air hose, then assemble the other hose with the attached sprayer and put the hose on the other connector that's on the bottle. Relieve any air pressure in the canister, then unscrew the canister from the top, add some A/C flushing solvent, re-assemble, then turn on the air (red handle) and spray air/solvent through the component you're flushing. Great product, five stars.

Only complaint is the air shut off valve is cheap and has too much play. Works as advertised.

This tool does what it says. It's based on the simple principle of pressurizing your flush solvent of choice in a metal can and then using a compressed air supply to shoot that solvent through your flushable components using the supplied nozzle. The nozzle resembles a typical compressed air blowgun but with a conical rubber end that will allow you to push it against just about any pipe up to about 1-1/4 inch in diameter and get a good seal. The fittings for the canister shut-off valve are standard 1/4"NPT. Be sure to tighten all the connections securely to prevent leaking fluid when pressurized. The unit has a handy hanging hook and enough yellow hose to get around your engine compartment if needed. All in all a good buy and worth the money to help get those AC pipes and components flushed. Be aware that compressors, expansion valves and some condensers should not be flushed. I was able to flush my evaporator while still installed but used rubber hoses on the inlet/outlet pipes to extend the connections to the flush nozzle.

Works great. Only thing that I noticed is sometimes the valve on the control end of the hose well not completely stop the flow.
