Maymom 20mm Flange Inserts (Long Plus) – 2-Pack, Freemie 25mm & 24mm Flange Compatibility

Overview

The Maymom 20mm Flange Inserts (Long Plus) come in a convenient 2-pack for versatile pumping setups. These silicone inserts are designed to slide into your existing cups, notably Freemie 25mm, to create a slim, consistent surface that suits a range of brands and flange shields. A practical note: they are not intended for 28mm Freemie cups. The result is a flexible accessory that can adapt your current equipment to new cups without buying a whole new system.

Care and safety

The inserts use a silicone that is BPA-free and DEHP-free. They’re designed for repeat use and can be cleaned via standard kitchen methods or steam-based approaches. Independent lab test reports are available for reference, and the design aligns with common food-contact material standards.

Real-world use cases

For many users, these inserts offer a practical way to extend the life of existing cups and shields. They can help create a consistent inner surface when switching between brands or cup sizes, potentially reducing leaks and improving comfort during longer pumping sessions. The easy-to-install design means you can experiment with fit during home pumping, at work, or while traveling—without a large change to your current setup.

Keep in mind that experiences can vary by individual hardware and flange combination. These inserts are intended as a flexible compatibility option, not a guaranteed outcome, and they should be used in accordance with the product notes and your pump’s guidelines.

Important note

If you rely on specific 24mm or 25mm configurations from certain brands, review the compatibility notes to ensure a match with Freemie 25mm cups or 24mm shield systems before purchasing.
