IVARONAL 6pcs Silicone Diaphragm for Momcozy S12 Pro/S9 Pro – Replacement Parts

Premium replacement diaphragms designed for trusted compatibility

IVARONAL presents a six-piece silicone diaphragm set crafted to replace worn components in select wearable breast pumps. While not the original Momcozy accessories, these parts are engineered to fit the listed models and aim to deliver dependable, steady suction without altering your pumping routine.

Compatibility and performance

The diaphragms and duckbill valves are designed to minimize air leaks and backflow, helping maintain a consistent pumping feel session after session. The closed-system construction helps keep milk contained in the container, reducing potential loss of suction and effort.

• OEM-like suction: parts are engineered to provide output comparable to OEM components for stable pumping performance.
• Leak-resistant design: tight top gaps reduce air escape, supporting a steady pumping rhythm.

Safe materials and comfort

Constructed from food-grade silicone that is BPA-free, soft, and odorless, these components offer a skin-friendly, snug fit designed for comfortable, lengthy pumping sessions.

• Soft, skin-friendly silicone for a comfortable seal.
• Durable, odorless material suitable for daily use.

Care and maintenance

After each use, rinse and wash the duckbill valves with warm soapy water. For sterilization, boil or steam at up to 100°C (212°F) for 5–10 minutes. Avoid aggressive brushes to protect seals.

• Wash gently with warm soap and water to preserve seal integrity.
• Sterilize by boiling or steaming up to 100°C for 5–10 minutes.
