BIG BLU needs very little introduction since it is used
by nearly 80% of all HVAC/R Technicians throughout
the U.S. and Canada.
Bubble leak detection was once considered gross and unreliable. To a certain
degree it was true because the dominant makers of leak detector solutions relied
on simple mixtures of soap and water
BIG BLU is a strong and persistent film forming liquid that has excelled in the
field identification of gas leaks. It remains, the only bubble/foam indicator
capable of detecting micro gas leakage down to 0.65 ounces per year.
Non toxic, non corrosive, biodegradable and approved for use on Oxygen systems.
