Exo Terra Mist Fogger Metal Key & Diaphragm
The exact wear part that restores fog output on a tired Exo Terra Fogger. The Exo Terra Mist Fogger Metal Key & Diaphragm (model PT2082) is the replacement membrane and membrane key for the Exo Terra Fogger (PT2080) — the two components that wear out with regular use and are the most common reason an otherwise working fogger stops producing mist.
Key features
- Genuine Exo Terra replacement part — matched to fit the PT2080 Fogger exactly, not a generic substitute.
- Diaphragm has a front and back — the black ring side faces downward on installation, so fitting it the wrong way round is the most common cause of a "new part, same problem" result.
- Includes the rubber washer, brass washer and ring nut needed to reseat the assembly.

Fitting notes
Make sure the fogger's internal cavity is completely dry before fitting the new diaphragm — trapped moisture is a common cause of a fogger that still won't mist after the part's replaced. Check the diaphragm's orientation, black ring side down, before closing the unit back up.
Suitable for, and not suitable for
Suitable for the Exo Terra Fogger (PT2080) only. It isn't a fit for other Exo Terra misting products such as the Monsoon range, which use a different mechanism.
Warranty and delivery
Covered by the manufacturer's standard warranty against manufacturing defects, in addition to your rights under the Australian Consumer Law. Ships as a small parcel.
Common questions
How do I know if I need this part rather than a new fogger?
If the unit powers on but produces little or no fog even after cleaning the ultrasonic disc with distilled water, the diaphragm is the usual culprit and is worth replacing before buying a new unit.
Does this fit the Monsoon misting systems?
No — it's matched to the Exo Terra Fogger (PT2080) specifically, not the Monsoon Solo, Multi or Nano misting systems, which use different nozzles and pumps rather than an ultrasonic diaphragm.
