ZeroR® AC UV Dye Leak Detector R134_ R12_ R22_ - 3 Can

Good

Worked great. Found my leak in the A/C compressor.

used to detect leak in auto ac system and worked ver

I was able to find the leak, but the price was pretty high.

These are one shot. No valve. Puncture and use.

The negative reviews are misleading especially the videos showing people using it improperly and complaining. You need equipment, AC hoses, to transfer the refrigerant, which it’s mostly in a gaseous state, to your vehicle. The cans are small but you really don’t want a full, 12 oz., can because your system is sensitive to being overcharged (small cans was another complaint). I used this (properly) and am very satisfied. Plus I have extra cans left over. Definitely recommend!

Scam product! Said it works with all UV lights. False, it does not. My adapter had a bad O-ring g and this stuff leaked all over my hands and the low pressure port. I replaced the O-ring and put the rest of the can as well as a second one in. Uses my UV light that I hunt scorpions with and nothing showed up. Absolutely nothing! The other parts of the engine glow under the light, but not this stuff. The charging hose was oily with the contents of the can with no glow. This is an expensive scam product. Don’t waste your money on it.

This stuff is great. With the right UV light, this dye glows like a radioactive leak on the Simpsons! Great stuff! I hope you only need one can and that your refrigerant systems are all not leaking!
