Opgroeie 4-Piece Flange Insert Set — 14mm Core, Flexible Sizing

Meet a versatile silicone upgrade for standard 24mm breast pump shields. This four-piece set includes two 14mm inserts and two 21mm inserts, giving quick options to tailor the fit without swapping hardware. The design focuses on comfort, compatibility, and ease of care, so you can approach pumping with a bit more confidence each day.

Why choose silicone flange inserts

• Soft, smooth edges and flexible silicone contribute to a comfortable feel during pumping sessions. The right size may help reduce friction and establish a more stable seal. These inserts are made from food-grade silicone and are BPA-free.
• Broad brand compatibility: fits popular shields from Momcozy, Spectra, Medela, Elvie, Lansinoh, and more; not compatible with 27–28 mm shields.

Practical sizing options

The kit includes two 14mm inserts and two 21mm inserts for a flexible fit that adapts to your routine. No need to alter your pump hardware to try different sizes.

Care and maintenance

• Dishwasher safe silicone with an included sponge cleaning brush for easy upkeep.
• Food-grade, BPA-free material designed for everyday use and reliable cleaning.
• Replace every 2 months to help sustain performance.
