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.

Key details

  • Includes thick and thin gaskets for one complete detector housing reseal
  • Maintains the water-resistant seal that protects sensor optics and wiring from HVAC duct contaminants
  • Quick swap during routine service - the cover comes apart easily and snaps back together in seconds, no detector rewiring needed

FAQs

What SuperDuct models does the SD-GSK gasket kit fit?
The SD-GSK fits all Kidde SuperDuct duct smoke detectors, including the SD-2W (conventional two-wire) and SD-4W (conventional four-wire) series.
When should I replace the cover gaskets?
Replace during routine maintenance if gaskets show wear, compression, cracking, or hardening. Fresh gaskets restore the water-resistant seal protecting sensor optics and electronics from humidity and contaminants in HVAC ductwork.
Does the SD-GSK include all gaskets needed for one detector?
Yes. The kit includes the thick gasket and thin gasket needed to reseal one SuperDuct detector housing cover. Order one SD-GSK per detector.
Can I replace the gaskets without removing the detector from the duct?
Yes. The SuperDuct housing cover is accessible without unmounting the detector. Remove the cover, swap the gaskets, and snap the cover back in place.
