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
Review: Instructions suck, useless product. - Do not waste your money on this GARBAGE the entire product leaked out and the INSTRUCTIONS ARE USELESS. The WHOLE LIQUID LEAKED TO SIDES NONE OF IT WENT INTO THE AC CHARGING HOLE

### ⭐⭐⭐⭐⭐ R-134a is black adapter just saying
*by J***R on August 11, 2025*

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.

### ⭐ Instructions suck, useless product.

### ⭐⭐⭐⭐⭐ GOOD PRODUCT and, an inexpensive way to resolve an evaporator leak.
*by A***R on May 14, 2026*

I admitted, I was a little skeptical about the effects and effectiveness of this product but, I am impressed. A leak on the evaporator coil is the last thing you want to hear when facing with an Auto A/C issue but, if you are interested this situation, concider using this product. Easy to install and after more than 6 months, it's holding pretty well with no side effects noticed.
