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 great!

Works as advertised, easy to inject into port and shows up nicely with 632 NM light

great product

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.

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.

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.

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

Tout à fait content. Je suis très satisfait

Petite quantité mais fait ce qu’elle doit faire

Har nu testat produkten och kan säga att den fungerar bra. Man får med en liten uv lampa i kartongen
