EXTERNAL is the sealant that must be applied externally to the components of the refrigeration and air conditioning system.
It was specifically created to eliminate all types of leaks up to 5mm that occur on metal and rubber parts
Refrigeration systems are sealed. External is resistant to lubricants, additives and refrigerants. It holds up
against temperature changes and is applied on the low and high pressure side (cold or hot). External
is effective with such metals as copper, aluminum and steel. You can also do it with thermoplastic pipes
consume.
It is resistant to mineral oils, POE, PAG, PAO oils, alchilbenzene.
It is also resistant to refrigerants CFC, HFC, HCFC, CO2, including R32 and R1234yf.
It is resistant to flushing media, including chlorate.
It is stable in the temperature range from -100°C to + 270°C.
The resistance to pressure depends directly on the size of the leak:
5mm = 40bar
2mm = 50bar
1mm = 57bar
