Compatibility and notes

Designed specifically for Momcozy S12 Pro and S9 Pro models. Not compatible with S9 or S12 pumps. These are not the original Momcozy parts; IVARONAL provides a compatible option.

Design and performance

The kit features a closed system with dual-channel anti-backflow, keeping gas and milk separate to minimize spills and protect the pump motor. The result is a leak-aware setup that supports steady suction during pumping.

• The top of the silicone diaphragm forms a snug seal to prevent gaps
• The duckbill valve directs milk flow in one direction for controlled transfer
• Soft silicone shields sit gently on the breast for comfortable wear

Materials and cleaning

All parts are BPA-free and made from food-grade silicone, offering a safe, odorless experience. After each use, wash with warm, soapy water and rinse well. For sanitation, you may boil or steam the parts at up to 100°C (212°F) for 5–10 minutes.

Usage ideas

Keep a spare kit on hand for quick swaps between sessions, travel days, or busy schedules. With these replacement parts, you can maintain a consistent pumping routine while prioritizing comfort and ease.
