The Mommy Material Freely Silicone Diaphragm is a replacement milk-path part for the Freely Electric Wearable Breast Pump. It acts as a barrier that keeps breast milk and moisture from reaching the motor and tubing, helping maintain a hygienic, closed pumping system while supporting consistent suction. If your suction feels less reliable or you can see moisture where it shouldn't be, a worn diaphragm is a common cause — and keeping a fresh spare on hand means you can get back to pumping without interruption.
Made from BPA-free, medical-grade silicone, this soft part is designed specifically for the Freely wearable pump. Because it's a flexible silicone component, it naturally stretches with use over time, which is why it's treated as a wear part that's replaced on a schedule rather than kept indefinitely.
How it works
- Barrier protection: The diaphragm sits in the milk path and blocks milk and moisture from travelling into the tubing and motor.
- Closed system: By keeping the milk path separated from the motor, it helps maintain a hygienic, closed pumping setup.
- Seal and suction: A soft, intact diaphragm helps the pump hold its vacuum, which supports consistent suction strength.
When to replace it
Because it's a soft silicone part, the diaphragm stretches and wears with use, so replacing it on time helps keep suction and hygiene where they should be. As a guide, replace it every 3 to 6 months if you pump between one and three times a day. If you pump more often than that, or you're exclusively pumping, replace it every 2 months — or sooner at the first sign of wear such as stretching or a loss of fit.
Best For
The Mommy Material Freely Silicone Diaphragm is a great option for parents who:
- Use the Freely Electric Wearable Breast Pump and want a genuine, compatible replacement part
- Have noticed weaker or less consistent suction and suspect a worn soft part
- Want to keep a spare on hand so a small part never holds up a pumping session
It won't fit other pump models — it's designed specifically for the Freely wearable pump.
