Review: This product really works - This stuff is awesome, finally found something that stopped the leak in my mini-split.
Review: R-134a is black adapter just saying - Item is actually easy to use. I was hesitant when I first got the item and messed up the first one and ordered a second one after I figured out what I did wrong. The product comes with two adapters for the two different types of coolant: R-134a (black) cap and R-1234yf (green) cap. It doesn't say, not that I've seen, which one goes on which. So I thought logically, well, to me anyway, low pressure on my R-134a is green, so it must be the green cap. I lost coolant, and product went everywhere. Then I laughed when it reminded me of the review I saw about losing all of the product through the top. Purchased another one, used the black cap, clicked it into place, attached product, injected, and let the vehicle run for 30 minutes. Only time will tell if it worked. Instructions should be included explaining a few things: * Do it when it has a fully charged AC system. * Start car. * Put on lowest AC setting. * Black cap is R-134a. * Green cap is R-1234yf. * Run car for 30 minutes. * Done. (update) This is the longest i have ever had ac in this car. So i guess that would mean it works

### ⭐ Didn't work
*by M***D on November 6, 2025*

did not display any leaks. The AC system gets low on R134 after 3 months but none of the joints or condenser fins showed any leaks.
