A/C Pro Car A/C UV Leak Detection Kit — Certified Pen Light Leak Detector with Safety Glasses & Batteries

This A/C Pro Certified UV Leak Detection Kit is a ready-to-use automotive solution that pinpoints refrigerant leaks using a high-intensity UV pen light, yellow safety glasses, and included batteries.

If you suspect an A/C leak, finding the source quickly saves time and prevents unnecessary parts replacement. The kit supplies a professional-grade ultraviolet pen light that works with all commercial UV dyes, plus yellow-tinted protective glasses and batteries so you can inspect O-rings, hoses, and fittings immediately after dye circulation. It’s compact, portable, and designed for garage or roadside troubleshooting.

How does the UV pen light reveal air conditioning leaks?

The pen light emits high-intensity ultraviolet illumination that makes compatible UV dye fluoresce, showing bright traces where refrigerant escapes. After adding dye to the A/C system and allowing circulation, you sweep the suspected areas with the light in low ambient lighting to locate the bright dye glow.

• High-intensity true ultraviolet output highlights even small dye trails.
• Works with all standard A/C UV leak detection dyes for broad compatibility.
• Handheld pen design reaches tight engine-bay spaces and lines.

What protective gear and power does the kit include?

Safety and immediate usability are built in: yellow-tinted glasses filter UV glare so you can spot fluorescence with reduced eye strain, and the kit comes with AAA batteries installed so the pen light operates right away. Always wear the glasses while inspecting to protect your eyes from UV exposure.

• Yellow-tinted protective glasses reduce UV glare and improve dye visibility.
• AAA batteries included for instant operation—no extra purchases required.
• Simple on/off switch located on the pen’s base for fast use.

Where in the vehicle should I look for leaks with this kit?

Focus on common failure points: O-rings at service ports, hose connections, compressor seals, evaporator lines, and condenser joints. Inspect components after dye has circulated and work in a dim or shaded area so the fluorescent dye shows clearly under the UV light.

• Service ports and fittings—frequent sources of seepage.
• Hose ends and clamps—check for cracks or loose clamps.
• Compressor shaft seal and condenser joints—look for concentrated fluorescence.

How do I use this kit step-by-step?

Install the included AAA batteries, add approved UV dye to the A/C system per the dye manufacturer’s directions, let the vehicle run to circulate the dye, wear the glasses, and scan suspect areas with the UV pen light. Work methodically from service ports and accessible hoses toward less accessible components.

• Insert batteries and verify pen light operation before beginning.
• Add dye following the dye product instructions and circulate.
• Reduce ambient light, wear glasses, and inspect with the pen light.

Who is this for: Technicians, DIYers, and fleet maintenance personnel who need a compact, effective way to locate refrigerant leaks in automotive A/C systems. The kit is ideal for garages checking multiple vehicles, roadside troubleshooting, and anyone who wants a professional-grade UV inspection tool that’s compatible with standard UV dyes and ready to use right out of the box.
