Extreme Humidity Desiccant Breather Replacement Cartridges
These Replacement Cartridges are used with Watchdog Extreme Humidity Desiccant Breathers. When the orange silica gel has turned dark green, remove the reusable top cap from the desiccant cartridge, dispose of the spent dark green desiccant cartridge, and then use the same top cap with a replacement cartridge.
