A pre-assembled set of two nipples, connected by a small tube. This assembly is designed to fit directly into the APS and APS-PRO humidity pumps.
The APS and APS-PRO humidity pumps work by a stretched tube over a motorised cog which forces water along the tube. Occasionally the nipples or tubing can be damaged or lost. This pre-assembled part will ensure that the pump begins working again.
NOTE: The APS or APS-PRO pump will need to be opened up to reveal the nipple assembly inside.
