2 x valves  and 4x membrane for all models of Medela's breastpumps, except Freestyle and Swing Maxi. This valve can be used with Spectra and Freemie breastshields as well.

- Valves and membranes are stored in a transparent plastic box for better protection.
- Valve is designed to have larger slope so that breastmilk can easily flow through the valve.
- Membrane is more flexible than Medela membranes, and it can respond faster to the pressure change during pumping.
- BPA free, and can be sterilized in water steam or boiling water.
- Every batch is tested to meet FDA's regulations on plastics that contact food. Testing report is available online.
