Four Seasons 69086 A/C Fluorescent Leak Detection Dye - 1 oz

The Four Seasons 69086 is a professional-grade fluorescent leak detection dye designed for automotive air conditioning systems. This UV-reactive dye is injected into the A/C system to help pinpoint refrigerant leaks that are difficult to detect through visual inspection alone.

Key Features:

• 1 oz bottle of fluorescent dye concentrate
• Compatible with R-12, R-134a, and other common automotive refrigerants
• Highly visible under UV/black light for easy leak detection
• Remains in system to help identify future leaks
• Will not harm A/C system components or affect refrigerant performance
• Professional-quality formula from Four Seasons, a trusted name in automotive climate control

To use, inject the dye into the A/C system, run the system for several minutes to circulate, then inspect components with a UV light. Leaks will appear as bright fluorescent traces, making it easy to identify the exact source of refrigerant loss. Essential tool for professional technicians and serious DIY mechanics diagnosing A/C system issues.
