Spectroline’s Cool Seal A/C Leak Sealer seals refrigerant leaks in compressors, condensers, evaporators, O-rings and hoses, and it’s now available in three different delivery methods. The CS-100CS Cool Seal EZ-Ject Kit features the EZ-Ject injector assembly, hose/coupler with check valve and purge fitting and two cartridges prefilled with Cool Seal. Each cartridge treats up to 2 tons of cooling. The larger CS-2CS Cool Seal BigEZ Cartridge works with the BigEZ injector, but can also be used with the EZ-Ject injector using a special adapter. The full cartridge treats 6 to 12 tons of cooling. The Cool Seal Stick Capsule (CS-3CS) allows Cool Seal to be injected right along with refrigerant. Each capsule treats up to 2 tons of cooling. Unlike aerosol can-type leak sealers, Cool Seal is non-flammable and has no storage-related safety issues, officials say. There is no need for system pump down, which company officials say allows the technician to see the contents injected into the system.
