Fluid Leak Detectors
LEAK-TESTING THE REFRIGERANT SYSTEMTest for leaks whenever a refrigerant leak is suspected and when performing a service operation which disturbs lines or connections.
LIQUID LEAK DETECTORS
There are a number of locations (fittings, valves, etc.) on the A/C system where a liquid leak detector solution may be used to pinpoint refrigerant leaks.
When the test solution is applied to the suspected area (using the swab attached to the bottle cap) bubbles will form within seconds if there is a leak.
For areas with restricted access (such as sections of the evaporator and condenser) an electronic leak detector is more practical for determining and locating leaks.
