21 mm nipple for Momcozy S9 Pro and S12 Pro breast pumps, set of 4 pieces

The 21 mm nipple for Momcozy S9 Pro and S12 Pro breast pumps, set of 4 pieces, is an accessory that adjusts the size of the pump cover for a better fit on the nipple and a more comfortable pumping process. It is a practical choice to optimize the seal and reduce discomfort caused by an improper size.

• Already adjusted for a more precise fit for comfort and efficiency during pumping.
• Reduces friction inside the cover chamber when the standard size does not fit.
• Quickly attaches to the cover and remains stable during use.
• Convenient set for everyday use and as a clean backup.

Compatibility

The 21 mm nipple is compatible with Momcozy S9 Pro and S12 Pro breast pumps. The adapter is designed to be used inside the 24 mm cover, allowing for a 21 mm diameter without changing the entire assembly.

Design and Materials

The adapter is made from food-grade silicone, BPA-free, suitable for components that come into contact with breast milk. The soft material offers a more pleasant sensation during use and a better fit inside the breast pump.

Proper Usage

For optimal results, select the correct size for your nipple and observe how it fits inside the chamber during pumping. If the nipple rubs or feels "tight," the adapter size should be adjusted. The 21 mm nipple is inserted into the cover until it fits evenly on the edges for a secure seal.

Maintenance

Wash the adapter after each use with warm water and dish soap, then rinse well. For sterilization, it can be boiled or steamed along with other breast pump parts. Allow all pieces to dry completely before reassembling.
