Four Seasons 69079 Fluorescent Dye for A/C Leak Detection

The Four Seasons 69079 Fluorescent Dye is an essential diagnostic tool for locating refrigerant leaks in automotive air conditioning systems. This specialized dye circulates through the A/C system with the refrigerant and glows brightly under UV light, making even the smallest leaks clearly visible at their source.

Key Features:

• Compatible with R-134a and R-12 refrigerant systems
• Glows bright yellow-green under UV/black light for easy leak identification
• Safe for all A/C system components including compressors, hoses, and seals
• Remains in system for continuous leak monitoring
• Concentrated formula treats multiple vehicles
• Works with PAG, POE, and mineral-based compressor oils

This fluorescent dye injection method is the most reliable way to pinpoint elusive A/C leaks that may be missed by other detection methods. Once added to the system, simply run the A/C and inspect all connections, fittings, hoses, and components with a UV light to identify the exact leak location. Ideal for professional technicians and DIY mechanics performing A/C diagnosis and repair.
