Valves and Membranes pack (4 valves, 6 membranes) for Medela

Includes 4 valves and 6 membranes. Suitable for all Medela pumps except the Freestyle. This is a Maymom product.

It's important to regularly change out these valves and membranes for optimum pumping output.

Can also be used with Spectra pumps if you prefer them to the duckbill valves.

• 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.
