TSI Supercool27361 A/C Flush Gun with Flow Control Valve and Improved Spray Head

Works beautifully. The can, hose and trigger nozzle are of high quality. I can think of other uses for the setup including pressurizing intake systems to look for leaks. I hooked it directly to my air compressor and flushed out my AC system very quickly.

When I first got the setup, the nozzle I received was different than what was pictured. What I had lasted just long enough for me to flush the system before it stopped working and sprayed line flush all over my driveway. I also had to go out and buy $10 worth of threaded connectors to adapt it to my compressor. Needless to say, I got on Amazon and just blasted the company. Jesse A advised that I should contact them for support, but I just blew that off. Huge mistake on my part - because when I did finally reach out to him (I got bored one day), he immediately offered to ship a replacement nozzle. He also volunteered that the kids have been updated to include the appropriate NPT fitting to adapt to common air compressor sizes. The replacement parts were FedEx'd and received within a week. Which is good, because I now need to replace my household air conditioner and - you guessed it - the lineset needs flushed.This is the mark of a good manufacturer - that they stand behind their product. No company which makes a poor product can afford to do this for long. Only a company committed to customer satisfaction and continuous improvement will step up like this.That being said - the replacement nozzle appears to be chemical resistant, as I've already used it to flush some components for a friends AC system with no problem. The adapter mated to my compressor perfectly, allowing me to get full pressure through the line. The sturdy construction on the hose, bottle and other assemblies means I'll be able to get a lot of use out of this product.

I have only used it once and it works ok, I bought this because I didn't want the hanger option, but after using it I now see why that would be a good option to havenothing leaked on it so I got a good one but I really didn't need this but there was no way to know that before purchase, I will most likely be able to find some off label uses for this going forward so I am happy with my purchaseI took away one star as it was expensive but the quaity seems appropriate for what I paid

Advertised as being able to hook to shop air. Even says so on the instructions on the bottle. Connection is for refrigerant hose. Fitting for shut off is one piece and cannot be removed to add shop air hose fitting.

Used with the TSI SuperCool solvent to flush AC lines was easy.Smells good, too.

REVIEW WRITTEN BY MY HUSBAND : I had the same experience that some of the other reviewers had. This comes with an unusual fitting to attach your shop air to. It was not compatible with any standard 1/4" or 3/8" fitting I could find. Unfortunately I didn't notice this till I went to use it when I had my car disassembled in my driveway. I went to a handful of stores from parts stores to big box stores and even hardware stores to no avail an hour and a half wasted....in the middle of a car repair. I ended up buying a different brand locally, and paying through the nose for it, but it worked just fine. Do yourself a favor, DON'T BUY THIS PRODUCT!!!!!!!!

Works great gor flushing the A/C system out in a semi.

Not sure why the others loved this product, I am sure it works but mine arrived WITHOUT the "improved" Head and the rubber of the "head" is WAY to hard. ALSO the Compressed air connection is not a common Quick Connect like a 1/4" Industrial, but looked like a Auto 3/8" connection or something. I could not find a female mate, so spend a day searching for a solution. I ended up removing the small valve on the cap which has a 1/8 NPT thread into the cap. Used a 1/8M-1/4MNPT adapter and a 1/4" Male Disconnect to solve it.To fix the head which did not have the bit of the tube extending on, I cut the back of the rubber off and slide it back.FOr the hardness, I happen to have bought an O-Ring set for replacing the ac o-rings on the hoses I remove for this cleaning. So I found a small silicon O-Ring the fit the small tube of the air gun and slipped it up to the black rubber. THIS makes a good soft seal to an ac hose end.May be I got a bad one, after all this is made in China
