Introducing Enviro-Safe UV Dye Charge — the fast and effective way to find refrigerant leaks in any A/C or refrigeration system. Each 2 oz can contains a refrigerant propellant blend combined with high-visibility UV fluorescent dye, allowing the dye to circulate through your system just like refrigerant. Wherever a leak exists, the dye escapes and glows bright yellow-green under UV light, making it easy to pinpoint even the smallest leaks. Compatible with all major refrigerants, including R1234YF, R134a, R12, R22, R600a, R290, and other HFC/HC blends. Safe for PAG, POE, and Mineral oils, and suitable for automotive A/C, HVAC systems, refrigeration units, and mini splits. Installation is simple — attach the hose or tap, connect to the low-side port, invert the can, and dispense. Then run the A/C and check all fittings, hoses, and components using a UV flashlight to locate glowing traces of dye. Use Enviro-Safe UV Dye Charge to: Quickly diagnose leaks without guesswork Avoid repeated refrigerant recharges Target repairs accurately instead of replacing parts blindly Save money on service calls or shop diagnostics Find the leak. Fix the leak. Get your A/C cooling again.
