Mastercool 53515 — MACH IV Flexible UV Leak Detection Light with Safety Glasses

The Original MACH IV: Flexible UV Light for Tight Spaces

The Mastercool 53515 MACH IV is the professional's choice for UV leak detection in tight, hard-to-reach areas. With its patented flexible wand, 4 true UV LEDs delivering brilliant fluorescent glow, and rugged ergonomic grip, this is the UV light that gets into spaces other lights simply can't reach. Perfect for finding refrigerant leaks in cramped engine bays, behind dashboards, and in confined equipment spaces.

Flexible Wand: The Game-Changer for Tight Spaces

The patented flexible wand is what sets the MACH IV apart from rigid UV lights. Bend it around obstacles, snake it behind components, and position the UV LEDs exactly where you need them — even in spaces where a straight light simply won't fit. This flexibility transforms difficult leak detection jobs into straightforward diagnostics.

Why This Matters: Refrigerant leaks often occur in the most awkward locations — behind condensers, underneath evaporators, in tight engine compartments. The MACH IV's flexible wand lets you illuminate these areas without dismantling components or contorting yourself into impossible positions.

4 True UV LEDs for Brilliant Fluorescent Glow

Four high-intensity true UV LEDs deliver brilliant illumination that makes UV dye glow intensely bright. Unlike cheaper lights with weak or off-spectrum LEDs, the MACH IV's true UV output ensures even the smallest dye traces are immediately visible. See leaks clearly, diagnose accurately, and complete jobs faster.

Rugged Ergonomic Grip for Professional Use

The rugged ergonomic grip is designed for all-day professional use. Comfortable to hold during extended leak searches, durable enough to withstand workshop conditions, and textured for secure grip even with oily hands. This is a tool built for real-world HVAC and automotive work.

How to Use the MACH IV for Leak Detection

1. Turn Engine and A/C System On — Start the system and allow it to run
2. Allow Dye to Circulate — Let UV dye circulate throughout the system (dye should already be in system)
3. Prepare the MACH IV — Ensure CR2 lithium battery is installed and fresh
4. WEAR PROTECTIVE GLASSES — Always wear the included UV-enhancing safety glasses
5. Turn Lamp On — Activate the MACH IV UV light
6. Search for Leaks — Use the flexible wand to access tight areas. Look for bright green/yellow glow where the system is leaking
7. Pinpoint Exact Location — The flexible wand allows precise positioning to confirm leak location
8. Clean After Repair — Clean the area around the leak after completing the repair

Important Safety Information

• ALWAYS WEAR PROTECTIVE GLASSES — UV light can damage eyes. Use the included safety glasses at all times
• Do Not Use Near Flammable Materials — Keep away from flammable liquids, gases, or materials
• LED Design Advantage — Unlike some UV lamps (53012, 53312), the MACH IV's LED design does not require cooling breaks and can be used continuously

Professional UV Leak Detection

UV leak detection is the fastest, most reliable method for finding refrigerant leaks. UV dye is added to the refrigerant system and circulates with the refrigerant. At leak points, the dye escapes along with the refrigerant. When you scan the system with the MACH IV, the escaped dye glows bright green or yellow under UV illumination, making even the smallest leaks immediately visible.

Perfect For

• HVAC technicians diagnosing leaks in tight equipment spaces
• Automotive A/C leak detection in cramped engine bays
• Commercial refrigeration service in confined areas
• Mobile service operations requiring flexible UV access
• Any leak detection job in hard-to-reach locations
• Professional installers verifying leak-free installations

Why Choose the MACH IV?

• Flexible Wand — Reaches spaces rigid lights cannot access
• True UV LEDs — Brilliant glow reveals even tiny leaks
• Patented Design — Original and best flexible UV light (Patent# 6,647,761)
• Professional Quality — Rugged construction for daily workshop use
• Complete Kit — Includes safety glasses and battery
• Time Savings — Find leaks faster without component removal
• Continuous Use — LED design allows extended operation without cooling breaks

The Flexible Advantage

The MACH IV's flexible wand transforms difficult leak detection jobs. Instead of removing components to access tight spaces, you simply bend the wand around obstacles and illuminate the area directly. This saves time, reduces labour costs, and minimises the risk of damaging components during disassembly. For professional technicians who regularly diagnose leaks in awkward locations, the MACH IV is an essential tool.
