Lichamp AC Oil Injector R134A, R1234YF Refrigerant A/C Dye Injector Kit with Adjustable Coupler and Oil Checkers

This worked perfectly it was easy to use no leaks no mess.

Worked as intended, great addition to my tool box for working on my old cars

Great tool. Its a bit more difficult to turn, but this tool WILL inject dye into a pressurized system.

The media could not be loaded.  So it definitely works as described and it’s very easy to use. The fitting is for I guess the R134a system so I needed to use the adapter since my system is R1234yf.Ok be careful when using the die it will spill when blessing the air out of the line so pay attention to that to what your doing or you’ll end up with everything glowing in the black lightthe other thing I should tell you is to put on gloves. Not rubber something thick to keep from getting splinters all in your handsI got mettle splinters from this things in both handling I used it 2x now and the 2nd time was much worse then the first timeYou’ll see in the pics I postedAnd idk what those filters are for or how to use them bc they don’t tell you anything about them or show you for that matter You get 2 so with that said I’m very happy other then my hand is missed upOk I hope this helps you guys out. A lotAnd 1 more thing your going to need some kind of case to store it in bc it’s nearly impossible to clean After use and it comes in a cardboard box.

havent tried yetas expected
