ENVIRO-SAFE UV Dye Charge – Leak Detector for R1234YF, R134a, R12, R22, R600a
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.
