Its use is particularly suitable for urgent interventions and in all those cases where it would become very complicated to manage a stationary system: ice cream counters, cold rooms, medicinal storage, vaccines, etc. Furthermore, the use of EXTERNAL is particularly recommended in applications with flammable refrigerant gases and in all those cases where welding is very difficult. EXTERNAL also allows immediate intervention on these systems, avoiding scrapping. Designed to effectively seal all types of holes up to 5 mm that occur on metal and rubber components in refrigeration and air conditioning systems, EXTERNAL resists lubricants, additives, refrigerant gases and washing liquids. Withstands temperature fluctuations and can be used on both high and low pressure side (hot or cold).
