Description
The Tracerline 8oz R-134a/PAG UV Fluorescent A/C Dye (TP3820-8) is a professional-grade solution engineered for precise leak detection in R-134a automotive air conditioning systems that use PAG oil. This highly concentrated, co-solvent-free dye is recognized as an OEM-grade product, ensuring it meets the stringent standards of vehicle manufacturers. When introduced into an A/C system, the dye circulates with the refrigerant, escaping at any leak point. Under inspection with a UV or blue light lamp, the dye fluoresces a vivid yellow-green, clearly marking the exact location of the leak. Its superior stability and extended shelf life make it a reliable choice for workshops and technicians. With an impressive service capacity of up to 32 vehicles per 8oz bottle, the TP3820-8 offers an efficient and cost-effective method for identifying and resolving A/C leaks, helping to restore system performance.
KEY FEATURES AND BENEFITS:
- R-134a/PAG System Compatibility: Specifically formulated for R-134a automotive A/C systems utilizing PAG (Polyalkylene Glycol) oil, ensuring optimal performance and compatibility.
- OEM Grade & Approved: Meets or exceeds original equipment manufacturer standards, with Tracerline dyes often factory-installed, assuring quality and reliability.
- Co-Solvent Free Formulation: This crucial feature prevents any adverse effects on the system lubricant’s viscosity or lubricity, maintaining the A/C system’s integrity. It’s certified to meet SAE J2297.
- High Concentration, High Capacity: An 8oz bottle is highly concentrated, capable of servicing up to 32 vehicles, providing excellent value and efficiency for professional use.
- Brilliant Fluorescence: Emits a bright yellow-green glow under UV or blue light, making even small, difficult-to-find leaks clearly visible and speeding up diagnostic time.
- Enhanced Stability & Shelf Life: Designed to be more tolerant of extreme temperatures and moisture, extending its shelf life up to 5 years, reducing waste and ensuring readiness.

HOW TO USE:
- Prepare the System: Ensure the A/C system is properly charged with R-134a refrigerant.
- Add Dye: Using a suitable dye injector (refillable inline or syringe type), add the recommended amount of Tracerline TP3820-8 dye into the low-side service port of the A/C system. Refer to the vehicle’s service manual or dye product instructions for precise dosage.
- Circulate Dye: Run the vehicle’s A/C system for at least 15–30 minutes to allow the dye to fully circulate with the refrigerant and oil throughout the system. This ensures the dye reaches any potential leak sites.
- Inspect for Leaks: With a UV or blue light inspection lamp (and fluorescence-enhancing glasses, if available), scan all A/C components, hoses, fittings, and connections. Pay close attention to areas that show signs of oil residue or discoloration.
- Identify Leaks: Any leaks will be clearly visible as a bright yellow-green glow where the dye has escaped.
- Repair and Verify: Once the leak is found, perform the necessary repairs. After repair, it’s recommended to re-inspect the area to confirm the leak has been sealed.
