What is it?
EXTERNAL is the leak sealant that is applied externally on the components of refrigeration and A/C systems. Specifically designed to effectively seal all types of leaks that occur up to 5 mm in the metal and rubber components of refrigeration equipment, EXTERNAL is resistant to lubricants, additives and refrigerant gases. It resists temperature changes and can be used interchangeably on the high and low pressure side (hot or cold).
Benefits
Can be used on metal circuit components, such as copper, aluminum and steel.
Can be used on thermoplastic tubing.
Resistant to mineral lubricants, POE, PAG, PAO and alkylbenzene.
Resistant to CFC, HCFC, HFC, R32, CO2 refrigerant gases, and even R1234yf.
Resistant to cleaning fluids, even chlorinated ones.
Resistant to a temperature range from -100°C to +270°C
Pressure resistance depends on the magnitude of the leak:
5mm=40bar
2mm=50bar
1mm=57bar
