Extreme is specifically designed for the safe repair of small refrigerant gas leaks that frequently occur all types of AC&R systems inc automotive AC.
The critical ingredients of Extreme are triggered into action only when there is a leak, mechanically building a flexible permanent seal.
Unlike other leak stop additives Extreme is Polymer-Free, meaning it doesn’t cure when in contact with moisture, that means it won't clog driers or expansion valves, it simply cures the leak.
