The ACE A04ASEZPRO+ EZ Leak Stop Pro is a professional-grade HVAC leak sealant formulated to stop small refrigerant leaks in 1.5-5 ton systems. The sealant circulates through the system via the service port and targets micro-leaks in metal components such as evaporators, condensers, and copper lines, forming an internal seal without harming compressors or coils. It is intended for preventative maintenance and emergency repair and is compatible with most refrigerants (consult manufacturer guidelines).
