UV Leak Detection Dye

A/C System

Fluoresces under UV light to make refrigerant leaks visible and identifiable at their source, enabling precise diagnosis.

UV leak detection dye is a fluorescent additive that mixes with A/C refrigerant and circulates through the system. When exposed to ultraviolet light, any leak will show up as a bright glowing spot, making it easy for technicians to pinpoint the exact location of refrigerant escapes. This is often the first step in diagnosing A/C cooling problems.
