Spare part specifically for the Medela Harmony Manual Breast Pump.

This is the complete Diaphragm with Stem and includes O-ring, also known as the Medela Harmony Flex Membrane Complete.

These parts can get wear'n'tear, and they control the whole suction performance of your pump so it's important to regularly check them and replace when needed.

This is not compatible with any other pump types or brands.
