Question about Medela Harmony Membrane with Style and O-Ring

Yes, the part fits on the Medela Swing. The Harmony diaphragms are compatible with Swing pumps, as confirmed by official Medela sources. The specific product number 054095 is not explicitly mentioned in the available documentation, but the compatibility of the Harmony accessories with the Swing is documented.

If you are unsure, please check the packaging for compatibility information or contact Medela support for confirmation of the product number. In case of suction problems, Medela always recommends checking the diaphragms and valves first.
