Benefits:

The professional UV leak locator kit offers a comprehensive solution for detecting refrigerant leaks in air conditioning (A/C) and refrigeration systems. Leading the way in UV leak detection, Mastercool provides a compact yet comprehensive kit that includes everything needed for professional leak detection. MACH IV Flexible LED UV light provides bright, long-lasting illumination with the flexibility to reach even the most challenging areas. LED technology is more durable and energy-efficient than traditional UV bulbs. The Mini Dye Injector (53809) features a replaceable 1-oz dye cartridge, making it easy to inject UV dye into the system. The cartridge design eliminates messy refilling. Includes 10 applications of UV dye to get you started immediately. The low-side hose with R134a coupler provides a quick connection to modern A/C systems, while the included R12 adapter ensures compatibility with older systems. UV-enhancing safety glasses protect your eyes while working with UV light and enhance dye visibility. Ten service information labels help you document leak detection work. Clam shell carrying case keeps everything organised and protected. Perfect for HVAC/R technicians diagnosing A/C and refrigeration systems, automotive technicians troubleshooting vehicle A/C, and professional installers who need to verify leak-free installations. UV dye circulates through the system and escapes at leak points, where it emits a bright glow under UV light. Finds leaks in condensers, evaporators, hoses, fittings, and other areas where refrigerant can escape. This comprehensive professional kit provides everything needed, eliminating the need for additional purchases. Professional-grade quality delivers reliable leak detection—an essential tool for any technician who regularly diagnoses refrigerant leaks.

Frequently Asked Questions (FAQ):

How does UV leak detection work?

UV dye is injected into the refrigerant system where it circulates with the refrigerant. When refrigerant escapes through a leak, the dye escapes with it and accumulates at the leak point. When you shine the UV light on the system, the dye glows brightly, making even the smallest leaks visible.

How many applications does the kit include?

The kit includes a 1 oz dye cartridge that provides approximately 10 applications, depending on system size. Additional dye cartridges can be purchased separately.

Can I use this kit on R1234yf systems?

This kit is designed for R134a and R12 systems. For R1234yf systems, you'll need an R1234yf-specific dye injector and coupler. See our 53123-YF or 53223-YF products.

How long does it take for the dye to circulate?

Allow the system to run for 10-15 minutes after injecting the dye to ensure it circulates throughout the entire system. For very small leaks, you may need to run the system longer or check again after the vehicle has been driven.

Will the UV dye harm the refrigerant system?

No, UV dye is specifically formulated to be compatible with refrigerant systems and will not harm seals, hoses, or other components. It's safe to leave in the system permanently.

Do I need to wear the safety glasses?

Yes, always wear the UV-enhancing safety glasses when using the UV light. They protect your eyes from UV exposure and enhance dye visibility by filtering out ambient light.

Can I use this kit in daylight?

UV leak detection works best in low-light conditions. For best results, work in a darkened area or shade. The dye will still glow in daylight, but it's much more visible in darker conditions.

How do I inject the dye into the system?

Connect the low-side hose to the system's low-pressure service port using the included R134a coupler (or R12 adapter for older systems). With the system running, use the mini dye injector to inject the dye through the hose. The system's pressure will draw the dye in.

What if I can't find the leak after injecting dye?

Very small leaks may take time to accumulate enough dye to be visible. Run the system for longer periods and check again. Also ensure you're working in a dark enough environment and wearing the UV-enhancing glasses.

Can I reuse the dye cartridge?

The cartridge is designed for multiple applications (approximately 10) until empty. Once empty, replace it with a new cartridge. The mini dye injector accepts standard replaceable cartridges.

How do I clean up dye after finding a leak?

UV dye can be cleaned with a suitable degreaser or refrigerant system cleaner. Clean the area thoroughly before making repairs to ensure a clean surface for new seals or fittings.

Is the MACH IV light rechargeable?

The MACH IV light in this kit uses replaceable batteries. For a rechargeable option, see our 53518-UV-220 Rechargeable UV Flashlight.
