Spectroline CS-3CS Cool Seal Stick Capsule

Air Conditioning Leak Sealer. Seals leaks in condensers, evaporators, O-rings and hoses. It can add years to older, out of warranty Air Conditioning and Refrigeration systems that leak small amounts of refrigerant.
How does it work?
When Cool Seal meets the leak and is therefore exposed to the atmosphere the drop in ambient pressure and temperature creates a scab-like seal over a leak. Cool Seal then continues to collect around the outer perimeter of the leak site until it is fully sealed.
Works with all popular refrigerants and oils.
