Tried using to add oil additive to geo system.Blew end right off dumping all of additive andWill not screw back together. This is junk don'tWaste your money. Very poor.

Nice unit but the part that you twist to inject the oil/dye is to loose and it throws off the scale for how much oil/dye your putting in i don't see a way to tighten it up so I guess just a design flow

Works...well built

Wont really hold 2 ounces. If you unscrew it enough to hold 2 ounces it will come apart. You can work around that easy enough for the price tho

Excelente inversión

I rarely give bad reviews, but this will be an exception. In my life, I have never bought such a terrible product. This 'thing' is a total piece of crap. Very cheaply made, and barely works. All the threads are poorly cut, and the outer tube would not rotate right out of the box. I had to start the rotation process using large channel lock pliers. Even after a total disassemble, cleaning with alcohol, and relubing with white lithium grease, the barrel still requires a very tight grip and a lot of struggling. There are small pieces of metal in all the threads, from the cutting process. Be concerned that these small pieces could get injected into your AC system, and destroy the compressor or expansion valve. Also, the 1/4" adapter is a through coupling, meaning, it is always open. So when you have the dye in this injector tool, there is nothing stopping the dye from dripping out the end of the coupling while you are in the process of screwing it on. In other words, dye on your bumper, radiator, valve cover, compressor, etc. How stupid. If I would have known how poorly it was made, I would not have spent $.01 for it. I'm not going to mention where it was made, but I think we all know the answer to that.

Working just fine

Lo que más me gusta de este inyector es que es muy fácil su método solo se enrosca e inyecta el aceite ya sea para refrigeracion automotriz o refrigeración residencial solo se debe lavar bien con agente de limpieza para no contaminar los diferentes sistemas
