The Mommy Material Milk It Silicone Gas Storage is the replacement backflow protector for the Milk It Single and Double Wearable Breast Pumps. It sits in the milk path between the collection cup and the pump, where its job is to stop expressed milk and moisture from flowing back into the pump mechanism — helping keep your milk path clean and protecting the motor from milk overflow.
Made from soft, food-grade, BPA-free silicone, the backflow protector is a wear part rather than an upgrade. Because the soft silicone flexes with every session, it naturally stretches over time, which is why keeping a fresh one on hand is worth it if you pump regularly. Having a spare ready means a torn or stretched piece never has to interrupt your pumping routine.
How it works
- Backflow barrier: The silicone piece blocks milk and moisture from travelling back toward the pump motor, keeping the milk path and motor separated.
- Seal and suction: When the silicone is intact it holds its seal, which helps the pump maintain suction; a stretched or cracked piece can reduce the suction you feel.
When to replace it
Backflow protectors wear with use, so it helps to inspect yours and swap it out before performance drops. As a guide from the supplier:
- Pumping 1 to 3 times a day: replace every 3 to 6 months.
- Pumping more than 3 times a day, or exclusively pumping: replace every 2 months.
- Whatever your routine: replace sooner if you notice any cracks, leaks, stretching or a drop in suction.
Cleaning
The backflow protector is easy to disassemble, clean and sterilise between uses. Always follow the cleaning and sterilising instructions supplied with your Milk It pump for the correct method.
Compatibility
This backflow protector is designed specifically for the Milk It Single and Double Wearable Breast Pumps. It is a model-specific spare, so it's suited to those pumps rather than being a universal fit across other brands.

- Own a Milk It Single or Double Wearable Breast Pump and need a genuine replacement backflow protector
- Pump regularly and want a fresh spare on hand before the current one stretches or tears
