Refrigerant Gas Leak Stop for Leakages Up to 5mm

EXTERNAL is a leakstop to be applied externally on refrigeration and air conditioning systems components. It is recommended for applications with flammable refrigerant gases. In these cases, welding is a very difficult operation: EXTERNAL let the operator intervene immediately even on this kind of systems, avoiding any scrapping. Specifically designed to effectively seal all types of leakages up to 5 mm on metal and rubber components of a refrigeration system, EXTERNAL is resistant to lubricants, additives and refrigerant gases. It actually resists to temperature changes and can be indifferently used both on the side of high and low pressure (hot or cold).


  •  Recommended for applications with flammable refrigerant gases (for example: R600 – R290)
  •  It can be used on metal components of the system such as copper, aluminum and steel
  •  It can be used on thermoplastic tubing
  •  It resists mineral lubricants, POE, PAG, PAO and alkyl benzene
     It resists refrigerant gases CFC, HFC, HCFC, CO2, R32 and R1234yf included
    It is resistant to flushing liquids, Chlorinated ones included

     It resists to a temperature range from -100 °C up to + 270 °C

    The pressure resistance depends on the size of the loss:  

     5 mm = 40 bar
    2 mm = 50 bar
     1 mm = 57 bar
