Refrigeration Technologies Viper Big Blu Brush-On Micro Leak Detector
Stop guessing and trace microscopic gas leaks instantly with Viper Big Blu Brush-On Micro Leak Detector. This is the ultimate, industrial-grade bubble detection formula downsized into a convenient, spot-treatment brush-on bottle. Trusted by OEMs and HVAC/R technicians worldwide, its ultra-sensitive, high-viscosity film clings to surfaces to identify even the most elusive leaks that standard sprays miss.
Equipped with an integrated, extra-long telescopic dauber, it applies a flat, smooth liquid boundary layer completely free of false-counter indicators. It is the most reliable tool in your diagnostic arsenal for pinpointing minuscule gas escapes.
Key Features & Benefits
-
Ultra-Sensitive Micro Leak Precision: Formulated to pinpoint micro gas leakages down to an incredible 0.74 oz/year (18.5 grams/year).
-
Long-Lasting Foam "Cocoons": Instead of popping instantly like soapy water, it forms persistent, expanding white foam cocoons that remain visible for up to two hours.
-
Integrated Telescopic Dauber: Features a built-in 10-inch (25cm) adjustable acrylic fiber dauber inside the cap, allowing you to coat tight joints and valves without counter-indicating bubbles.
-
Universal Gas & Oxygen Safety: Tested completely safe for any pressurized gas line, including HVAC/R refrigerants, natural gas, propane, and hospital-grade oxygen.
-
100% Non-Corrosive Formula: Engineered with a neutral pH—it will not pit, corrode, or degrade copper, brass, steel, aluminum, or plastic fittings.
-
NSF Certified & Food Safe: Eco-friendly, non-toxic, and biodegradable formula certified by the NSF for safe use in and around food processing environments.
Step-by-Step Diagnostic Instructions
-
Isolate: Turn off or safely disconnect power to the system being tested.
-
Apply: Unscrew the cap and use the telescopic brush to apply a flat, smooth liquid film over threaded connections, seals, joints, or valves.
-
Inspect: Standard leaks will react immediately. For complex micro-leaks, allow 5 to 30 minutes for the solution to react and form distinct white foam clusters.
-
Vibration Test: Power the unit back on to inspect the coated sections under active system vibration.
-
Clean: Wipe or rinse the surface clean if fresh water is available (evaporator coils require no rinsing).
