The Big Blu MicroLeak Detector is a professional-grade leak detection solution formulated to reveal even the smallest system leaks with thick, long-lasting foam. It is trusted by HVAC technicians worldwide for its safety, accuracy, and ease of use.
Trusted Industry Standard:
Detects micro-leaks instantly
Non-corrosive, non-flammable
Works on all pressurized systems
Small leaks in AC and refrigeration systems can lead to:
Loss of refrigerant or gas pressure
Higher operating costs and energy consumption
Reduced cooling or heating performance
Moisture intrusion and corrosion
Compressor damage over time
Safety hazards in gas systems
A reliable leak detector is essential to prevent system damage, downtime, and costly repairs.
This high-sensitivity formula creates long-lasting, ultra-viscous bubbles that cling to surfaces—even overhead or on vertical piping—to reveal micro leaks.
Produces stable foam for clear visual leak detection
Works in extreme temperatures (HVAC and refrigeration environments)
Clings to joints, fittings, valves, coils & pressurized lines
Non-corrosive formula safe for metals and plastics
Ready-to-use, no dilution required
Ideal for HVAC technicians, gas installers, refrigeration engineers, and maintenance professionals.
