CMTOOL AC Oil Dye Injector Tool R134A Compressor Oil Injector Kit, Car A/C Kit with Snap Quick Coupler, Auto Automotive HVAC Tool

Awesome product. Works as expected and connector fits perfectly.

Worked well. Used it to install some ac leak fix and it did the job. Would buy again.

This would have been a 5 star product if they had included all the connectors as described. They included just one and it was not an R134a that I needed. Had to go buy one at the local parts store for another $8 so this ended up costing me a lot more than expected. Couldn’t wait to send it back and get a new one. Had to get my AC fixed. Besides that it seems to be good quality. Used it for Red Angel AC sealer 2oz bottle and it was perfect for that. One bottle fills the reservoir enough that no air can get trapped when you thread on the cap. A little will leak out around the threads insuring you have nothing but sealer in the reservoir before injecting it into the AC system when you recharge it.

You NEED a tool like this. Works great for injecting some dye and oil into the system after repairs or to diagnose leaks. Well built but my ONLY complaint is the valve that comes with it is garbage. Swap out the valve for anything else and you are good to go. Great tool.

This tool is made of top quality materials and very easy to use, it helped me cure the leak in the accumulator of our Jeep!

Great product, good price.

Your damn male fitting doesn’t even work! Are you kidding me. It won’t even work with the female fitting you sent. What a joke. I had to shave the end of the male fitting down a little bit with a grinder until it would fit! Lame!

Worked well. Wish it had a site glass s you know the oil went in.
