S9 Pro Breast Pump Replacement Parts Kit

This is an official Momcozy replacement parts set for the S9 Pro breast pump, covering all the washable components in one kit.

The set includes a 24mm flange, milk collector, diaphragm, duckbill valve and linker — all made from BPA-free, food-grade silicone. The diaphragm and duckbill valve each feature a textured surface for a more secure seal and consistent suction. The milk collector holds up to 180 ml.

Momcozy recommends replacing washable parts every one to three months with regular use, or sooner if any piece becomes deformed or discolored. This kit is FSA and HSA eligible.
