medela harmony diaphragm


This spare part is for the replacement of a worn, damaged or lost/missing diaphragm for the Medela Harmony breast pump.

This piece is also referred to as a 'diaphragm/stem with O-ring'.

The stem (with the O-ring) is inserted into the hole on the upper side of the diaphragm - the stem and the diaphragm are part of the Harmony pump's handle.

This part includes three pieces - the stem, with white O-ring and the diaphragm.
