Opgroeie 4Pcs 12mm Flange Inserts for 24mm Shields – Compatible with Momcozy, Spectra, Medela

Enhance your pumping comfort with versatile flange inserts

Opgroeie offers a practical set of flange inserts designed to pair with standard 24mm breast pump shields. This 4-piece pack centers on a 12mm insert size, with an additional 21mm option to tailor fit for different body shapes and pumping setups. The lineup covers popular brands such as Momcozy M5/M6/M9, S12 Pro, S9 Pro, V1 Pro, V2 Pro, Spectra, Medela, Elvie, and more. Note: not compatible with 27-28mm shields.

In everyday use, the right size can influence how the flange sits against the skin during a session, potentially contributing to a steadier seal and a comfortable feel. The 12mm option is well suited for a tighter opening, while the 21mm size offers a broader fit where needed, helping you customize your pumping experience without changing your shield.

Easy, practical design for real life pumping

Installation is quick and simple: insert or remove the insert from your standard 24mm flange to switch sizes on the fly. The inserts are made from food-grade silicone and are BPA-free, designed for durable use and straightforward cleaning. A sponge cleaning brush is included to simplify maintenance and keep the parts looking fresh between sessions.
