The Medela Valve and Membrane Set is a replacement pack of the small, soft milk-path parts that help your pump hold its vacuum. If your Medela pump feels like it isn't pulling the way it used to, or you've spotted a torn, warped or worn valve, these are the wear parts to reach for before assuming anything is wrong with the pump itself. They fit into your existing setup and are quick and easy to swap in, so you can get back to expressing with minimal fuss.
This valve and membrane set is compatible with the Medela Swing, Harmony and Mini Electric breast pumps. It suits the older models of these pumps and is not compatible with the newer Swing Maxi Flex or Solo Flex, so it's worth confirming which model you have before ordering. Keeping a fresh set on hand means a small worn part never has to interrupt your routine.
How it works
- Vacuum seal: The membrane and valve work together as the soft, flexible parts of the milk path. When they're in good condition they close cleanly, which helps the pump maintain its vacuum and keep suction consistent.
- Natural wear parts: Because they flex with every cycle, valves and membranes gradually lose elasticity or develop small tears over time — replacing them restores the parts to their original, intact state.
When to replace
Medela recommends changing the valves and membranes after three months of use. It's also worth swapping them sooner if you notice a valve looking torn, stretched or misshapen, or if suction feels weaker than usual. This set gives you spares on hand so a worn part never has to hold up a pumping session.
Best For
The Medela Valve and Membrane Set is a great option for parents who:
- Own an older Medela Swing, Harmony or Mini Electric pump and want to keep it working well
- Are following Medela's guidance to refresh these parts every three months
- Want a spare set on hand so a small worn component doesn't interrupt expressing
It may not be the right fit if you:
- Have the newer Swing Maxi Flex or Solo Flex, as this set is not compatible with those models
Pandylane Pro Tip
Pandylane Pro Tip: Keep a spare valve and membrane tucked into your pump bag. They're inexpensive, wear quietly over time, and having a fresh set within reach means you're never caught out mid-session by a part that's simply reached the end of its life.
