Ameda Universal Soft Breast Pump Flange Inserts These are a line of soft, flexible silicone inserts designed to be placed inside larger Ameda breast flanges to create a smaller, more comfortable, and customized fit. Key Features Material and Comfort: Made from soft, flexible silicone that helps reduce friction and irritation often associated with hard plastic flanges, promoting a more comfortable pumping experience. Customizable Sizing: The inserts are available in a wide range of small sizes, typically from 11mm to 21mm (including 11mm, 13mm, 15mm, 17mm, 19mm, and 21mm). This allows mothers to find a precise fit to maximize milk expression efficiency and comfort. Compatibility: They are designed to fit seamlessly into Ameda's standard 25mm flanges as well as all Ameda GLO Wearable Breast Pump flanges. They work by creating a smaller tunnel opening inside the larger flange. Secure Seal: The soft material helps create a secure vacuum seal, which is important for minimizing leaks and promoting effective suction and milk output. Packaging: Typically sold as a pair (2 inserts) for double pumping, though they may also be available in single packs or multi-size multipacks. Safety: The inserts are made from materials that are BPA and DEHP free. Contents One pair (2 inserts) of the selected size (e.g., 17mm) of Ameda Universal Soft Breast Pump Flange Inserts.
