Following application, the ProSeal® sealant moves through your air conditioning unit's system with the refrigerant to locate minor leaks. Our sealant interacts with the surrounding air and moisture at the leak location to create a lasting seal. The ProSeal® successfully closes refrigerant leaks that do not have a complete loss of charge within 7 days.
Any ProSeal® sealant that remains unused will stay unaltered in the system to address additional leaks in the future.
