60ml UV Fluorescent Dye – Car A/C Leak Detection Tracer Tool

Spot A/C Leaks Fast with UV Fluorescent Tracer Dye

Stop guessing where your car's air conditioning system is losing refrigerant. This 60ml UV Fluorescent Tracer Dye is specially formulated for automotive A/C and refrigeration systems, making invisible leaks instantly visible under UV light. Whether you're a professional mechanic or a DIY car enthusiast, this easy-to-use leak detection solution saves time and keeps your A/C running at peak performance.

Made in Mainland China.

Key Features

• Universal Compatibility: Works with most compressor-based automotive A/C and refrigeration systems, including R-134a and similar refrigerant circuits.
• Multi-System Detection: Ideal for detecting leaks in A/C refrigerant lines, oil circuits, power steering systems, fuel lines, automatic transmission fluid, coolant, and hydraulic systems.
• Bright Fluorescent Glow: The dye fluoresces vividly under UV/black light, pinpointing even the smallest leak in pipelines, joints, and seals.
• Eco-Friendly Formula: Pollution-free and environmentally responsible — safe for use within your vehicle's systems without degrading performance.
• Simple to Use: Added just like refrigerant oil through the low-pressure filling port — no special equipment needed beyond a standard UV flashlight.
• 60ml Capacity: Generous volume suitable for one or multiple inspections depending on system size.

How to Use

1. Add the UV dye through the low-pressure filling port in the same manner as refrigerant oil. For dual-zone vehicles, ensure both front and rear A/C switches are turned on.
2. Allow the A/C system to run for approximately 10 minutes so the dye circulates fully through the refrigerant lines.
3. Put on protective UV-blocking glasses and use a UV flashlight to scan all pipes, joints, seals, and components.
4. Any area displaying a fluorescent glow indicates a leak — mark those spots for repair or component replacement.

Frequently Asked Questions

Q: Is this UV fluorescent tracer dye compatible with R-134a automotive A/C systems?

A: Yes. This UV fluorescent tracer dye is formulated for universal compatibility with most compressor-based automotive A/C and refrigeration systems, including those using R-134a and similar refrigerants. Always confirm your system type before adding any dye.

Q: Do I need a special UV flashlight to detect leaks with this dye?

A: Yes, a UV or black-light flashlight is required to illuminate the fluorescent dye and reveal leak points. Protective UV-blocking glasses are also recommended during inspection for eye safety. The flashlight is not included — it is sold separately.

Q: Can this dye be used to detect leaks in systems other than the A/C refrigerant circuit?

A: Absolutely. This versatile tracer dye is effective for detecting leaks across multiple automotive fluid systems, including oil, power steering, fuel, automatic transmission fluid, coolant, and hydraulic lines — making it a multi-purpose diagnostic tool for the whole vehicle.

Q: How long does it take for the dye to circulate through the A/C system?

A: After adding the dye through the low-pressure filling port, run your vehicle's A/C system for approximately 10 minutes. This allows the tracer to fully circulate through all refrigerant pipelines and components before you begin the UV inspection.
