The SD-GSK is a replacement cover gasket kit for the Kidde SuperDuct line of duct smoke detectors. It includes the thick and thin gaskets that seal the detector housing cover, keeping humidity, dust, and other contaminants away from the sensor optics and electronics inside.
Keep your SuperDuct detectors sealed and serviceable
SuperDuct detectors are built for harsh HVAC duct environments, but the cover gaskets take the brunt of that exposure over time. Worn or compressed gaskets compromise the water-resistant seal that protects internal components. The SD-GSK gives you fresh gaskets to restore that seal during routine maintenance or detector servicing - no need to replace the entire housing.
