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

It work great doing all my cars now. I will know if a leak so up very impress it work so easy to do.

Works great!

Finding refrigerant leaks used to be the most frustrating part of my HVAC service calls. I was so tired of constantly spraying soap bubbles and chasing phantom alerts with electronic sniffers. This UV dye has been a complete game changer this summer. On several units, the leaks showed up almost immediately after charging it in. When you put on the UV glasses and shine the blacklight, the leak points glow brightly with unmistakable neon green—no second-guessing. I’ve attached photos of the product and actual job-site results under UV light: you can clearly see the exact leak spots on the coils and joints. It has saved me hours of diagnostic time. Essential tool for any serious HVAC tech!

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.

Worked as it should.

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

great product

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.

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
