A/C Oil Injector Tool R134A/R410A R22 R12, Podoy Refrigerant A/C Dye Injector Kit with Snap Quick Coupler and Connector Hose & 2 OZ Hand Turn Screw & 1/4" SAE Scale

Works grate !!! Easy to use.

Good quality, easy to use.

So, I've using this tool to add or refill A/C oil to several vehicles. So far, oil injector tool is operating accordingly and I have no complains at all. It is made with good materials and gaskets seem to be holding pretty well so far. Only issue is that the oil injector comes with a decal showing oil proportions, on which I believe it should be engraved instead of a common printed label.

Well made and works for my application

Used product to put in red angel a/c stop leak. Worked fine.

Very good quality - A must have for A/C work.Very easy to use and measure exactly the right amount of oil.Highly Recommend

This is great for injecting oil and dye into r-12, r134a refrigerant which is good the only problem i see at this time is they do not offer a 1234yf fitting. I know this stuff is new but its gonna be around for a while. I checked on my tool trucks that come by and they cant seem to find anything either. Guess ill keep looking

I, like many others, am having trouble removing the bottom end cap. I have tried using Liquid Wrench, PB Blaster, heat, etc. I can turn the bottom end cap (with a great deal of force) but the cap is still not coming off. When I purchased this product (in late 2021), there were several buyers with different questions that I noticed are not in today's list of questions. Is the vendor (i..e., Podoy Direst) removing past questions in order to make the product look more appealing to potential buyers? I would not recommend this product to anyone and I wonder why Amazon would partner with this vendor, when so many customers have had the same problem that I am having with this product.
