Liquid Leak Detectors & Pressure Testing

Due to their lack of sensitivity, liquid/bubble leak detectors have very limited usefulness and are not recommended.

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 arc 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.
