Errecom Brilliant - 8.5 fl oz (250 ml), Fluorescent UV Dye for Detecting Refrigerant Gas Leaks in Air Conditioning and Refrigeration Systems, 250 ml Bottle with Dispenser

Works great!

great product

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.

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.

Working great

Worked great found the leak.

Really a 0. Followed AI in instructions since none were provided. Syringe blew out on contact . It’s no longer available on the website.

With a black light, it glows like nuclear sludge. Found and fixed my ac leak

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.

Parfait pour détecter les fuites de climatisation de ma voiture, le produit marche vraiment bien, il m’a détecté une fuite au niveau du bouchon

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
