Momcozy Diaphragm and Duckbill Valves for S9 Pro/S12 Pro Breast Pump

Momcozy diaphragm and duckbill valves for S9 Pro/S12 Pro breast pump

The silicone diaphragm and duckbill valves are the breast pump parts that wear out fastest and have the greatest effect on pumping effectiveness. The original Momcozy replacement set lets you restore the S9 Pro and S12 Pro breast pumps to full working order without replacing the whole device.

What these parts do

The diaphragm is responsible for maintaining the proper seal in the pump chamber, which results in a stable vacuum level during pumping. The duckbill valve directs the expressed milk down into the container, preventing it from flowing back toward the pump mechanism. When one of these parts wears out or deforms, the effectiveness of pumping drops noticeably.

Original parts, secure fit

The set is compatible only with Momcozy S9 Pro and S12 Pro breast pumps, so the parts fit perfectly, without the play and leaks typical of cheaper replacements. The material is food-grade silicone, BPA-free, safe for milk intended for the baby.

Simple replacement and care

The diaphragm and valves are easy to remove and install yourself, without tools. After each use, the manufacturer recommends washing the parts with warm soapy water and regularly sterilizing them in boiling water, which extends the life of the parts and maintains high hygiene of the expressed milk.
