Air conditioning leak stops: yes or no?

Stop leak for vehicle air conditioning: what is the best solution?

It’s summer and hot almost everywhere in the Northern Hemisphere.

After months of inactivity most of air conditioning and refrigeration systems are back to their normal and intense performances but we often find out that the circuit has leakages problems: cooling rooms and cockpits become a very difficult operation.



Corrosion, a non-welded joint and poor installation are among a range of problems that can often cause gas and its lubricants to leak in air conditioning and refrigerant systems.
AC/R systems are obviously under wear processes and require maintenance. Over the years, micro leakages formations are inevitable because of different causes:

  • acid formation within the circuit;
  • when the system is in motion (as in the case of vehicles) and therefore under constant stress, leakages formation is a very common event;
  • more generally, poor installation.



EXTREME ULTRA is a high performance air conditioning and refrigeration leak stop designed in ERRECOM labs in order to repair these refrigerant leaks, by guaranteeing a complete, permanent and elastic endurance of the system.



  • Its formulation is 100% safe: as a polymer-free sealant it does not react to air or humidity, avoiding any possible clogging;
  • EXTREME ULTRA is safe even for the operator: the product is actually not dangerous at all. On the contrary, other solutions now on the market are defined as cancerous. EXTREME ULTRA is not;
  • Errecom labs have projected a solution that guarantee better performances even with less product in the system: EXTREME ULTRA innovative molecules allow to use a very small dosage of leak stop. Only 6ml can treat AC/R systems up to 21kW (6tons). These kind of system were previously treated with 42ml;
  • Compatible with all refrigerant gases, R32, R134a & R1234yf included;
  • It has UV dye addiction.



EXTREME ULTRA is a mix of components which are gas and lubricant friendly. These components circulate inside AC/R systems, exactly as blood platelets do. The molecules inside EXTREME ULTRA are really similar to the flow: that is why they do not get separated. In case of leakage, they are dragged together with refrigerant gas and lubricant towards the outside of the system.

EXTREME ULTRA accumulates in the leakage point, slowing down the flow of the refrigerant gas.

The leak becomes smaller and smaller, the flow slows down and the quantity around the molecules reduces consequently. Therefore all the granules melt together, closing up the leakage perfectly.

Furthermore, EXTREME ULTRA is ideal for preventative application.
