The Tracerline 12pcs 0.25oz R-134a/PAG UV Fluorescent A/C Dye (TP3820-P12) is a professional-grade solution engineered to accurately detect leaks in automotive R-134a air conditioning systems that utilize PAG oil. This comprehensive package includes twelve individual 0.25 oz (7 ml) bottles of specialized fluorescent dye, each precisely measured to service one vehicle. When introduced into the A/C system, this high-quality dye circulates with the refrigerant and oil. Should a leak be present, the dye exits the system along with the escaping refrigerant and oil.
KEY FEATURES AND BENEFITS:
- Precise Leak Detection: Formulated to glow brightly under UV light, making even microscopic R-134a/PAG A/C system leaks easily visible and identifiable.
- R-134a/PAG Compatibility: Specifically designed for seamless integration with R-134a refrigerant and PAG oil systems, ensuring optimal performance without compromising system integrity.
- OEM-Grade Quality: Meets SAE J2297 standards, certifying its safety and effectiveness for use in original equipment manufacturer (OEM) specified A/C systems.
- Pre-Measured Doses: Each of the 12 bottles contains 0.25 oz (7 ml) of dye, providing a convenient, single-vehicle dose, eliminating guesswork and ensuring proper application.
- Enhanced Stability and Shelf Life: Features an improved formula that offers superior stability across varied temperatures and extended shelf life of up to 5 years, ensuring reliability over time.
- Does Not Affect System Lubricant: Engineered to maintain the proper viscosity and lubricity of the A/C system’s oil, preventing any adverse impact on system performance or component wear.
- Time-Saving Diagnostics: Significantly reduces diagnostic time by quickly revealing leak points, allowing for faster repairs and minimizing vehicle downtime.

HOW TO USE:
- Add Dye to A/C System: Using an appropriate dye injector or charging hose, introduce one 0.25 oz bottle of Tracerline TP3820-P12 dye into the low-side service port of the vehicle’s R-134a A/C system.
- Run A/C System: Operate the vehicle’s A/C system on its highest fan setting and coldest temperature for at least 5–10 minutes to allow the dye to circulate thoroughly throughout the entire system.
- Inspect for Leaks: Turn off the A/C system. Using a UV (ultraviolet) leak detection lamp, systematically inspect all A/C components, including hoses, fittings, evaporator, condenser, compressor, and any suspected leak areas.
- Identify Leak Location: Look for a bright green glowing area, which indicates the precise location of a refrigerant leak. The dye will fluoresce brightly wherever it has escaped the system.
- Repair and Verify: Once the leak is identified, perform the necessary repairs. After repairs are complete, re-inspect the area with the UV lamp to confirm the leak has been sealed.
