When using any gas-based electronic leak detector, finding the exact location of the leak site can be difficult, especially if several connections or components are all located within a small area. If CO2 is used in the A/C system for leak detection, the CO2 can cause a specifically-formulated foam to change color, pinpointing the source of the leak. The Bullseye Leak Seeker foam is applied to the general area identified by the CO2 sniffer and any leaking CO2 will change the color of the foam from a pinkish red color to yellow at the exact location of the leak site. This Bullseye Leak Seeker foam totally eliminates false leak detection. Additionally, if the leak volume is large, the foam will not only change from pinkish red to yellow but will also produce one or more bubbles at the leak site. The foam can correctly indicate the size of the leak site by how much of the foam changes color, how fast the foam changes color and how many bubbles are formed.
