Spectroline’s Cool Seal A/C Leak Sealer adds years to out-of-warranty AC&R systems by sealing refrigerant leaks in compressors, condensers, evaporators, O-rings and hoses. It’s now available in three delivery methods. The Cool Seal Stick Capsule (CS-3CS) allows Cool Seal to be injected right along with refrigerant (2-bleed valves required). Each capsule treats up to 2 tons of cooling.

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 BigEZCartridge 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.

Cool Seal remains safely in the system to guard against future leaks and is an economical alternative to expensive parts replacement on older AC&R systems. Unlike aerosol can-type leak sealers, it is non-flammable and has no storage-related safety issues. There is no need for system pump-down, so the technician can see the contents injected into the system.

Cool Seal meets ASHRAE 97 standard for chemical stability. Its non-polymer, oil-soluble formula is safe for all AC&R system components and recovery equipment. It works in all popular AC&R systems, including high-pressure R-410A systems.
