Compatibility

• Connects between a Medela Sonata connector and Spectra S1, S2 pump (see photos).

• Connects between a Maymom wide mouth flange/connector and bare end tubing (see photos)

Installation

• To install the adapter, put 1-2 drops of water inside the blunt end of the tubing, then insert the connector adapter into it. You might not be able to push it all the way in. It is ok. It will stay sealed for your pumping purpose. (See photos).
