Fluorescent Leak Detectors

Due to restricted visibility in today's refrigerant systems and their lack of sensitivity, liquid/bubble leak detectors have very limited usefulness.

CAUTION: R-134a service equipment or vehicle A/C systems should not be pressure tested or leak tested with compressed air. Some mixtures of air/R-134a have been shown to be combustible at elevated pressures. These mixtures are potentially dangerous and may result in fire or explosion causing injury or property damage. Additional health and safety information may be obtained from refrigerant and lubricant manufacturers.
