ERRECOM Brilliant - 0.2 fl oz (7.5 ml), Fluorescent UV Dye for Detecting Refrigerant Gas Leaks in Vehicle A/C Systems, Includes R134a Adapter

Works "brilliantly" for finding leaks in the HVAC system. A UV light makes this stuff shine bright where its leaking. I found the welds leaking on my condenser within seconds of putting it in my car's HVAC system. Comes with all you need.

Worked great found the leak.

Working great

Without the car running, the low pressure line is too pressurized and it wont let you inject. Make sure the car's AC compressor is running by setting the AC to its lowest setting and blasting the AC with the windows down so it wont turn off. This will relieve pressure and let you inject the dye. No instructions with the product which sucks. But this is such a cheap solution compared to others I'm still giving it 4. It would be 5 stars if they simply included paper instructions in the product.

Much cheaper this way if you don't need all the other stuff included in various kits. Found the leak in my fridge and it now keeps my beer cold in the garage. Fluorescent UV Dye

This is basically useless, no instructions provided. Freon will blow out syringe when attached to low side port. If this kit is only for use on discharged systems it should be labelled as such.

Arrived on time, as described

It works

Hat mir tatsächlich geholfen, mein Leck zu finden. Wer also wie ich eine Undichtigkeit hat, ist dass das richtige Produkt. Einen Stern abzug, da der Preis etwas hoch ist.

Flourescent die. Does exactly what it's meant to do plus more. Ideal for adding uv die to smoke leak detector fluid, plus air conditioning systems.

Tout à fait content. Je suis très satisfait

Petite quantité mais fait ce qu’elle doit faire
