Mompmuir Flange Inserts 16pcs (15–22mm) for 24mm Pumps – Compatible with Medela, Spectra, Elvie

Overview

Introducing the Mompmuir flange sizing kit, a 16 piece set that covers eight sizes from 15 to 22 mm. Designed to fit most 24 to 25 mm pump shields, this kit helps you tailor the fit for comfort and pumping efficiency without guessing at size.

How it works

Choosing the right insert allows you to customize the shield opening to your nipple tunnel. The soft silicone is transparent and gentle against skin, supporting a more comfortable pumping session and potentially smoother milk expression. The design prioritizes a snug, supportive seal while minimizing pressure points.

• Comfort first: flexible silicone cushions and adapts to your body to reduce irritation
• Potential efficiency: a well-fitted shield can support steadier pumping sessions

Compatibility

Compatible with a wide range of popular brands including Medela, Freestyle, Swing Maxi, Harmony, Spectra S2/S1, Momcozy S9/S10/S12 Pro, M5/M6/M9, Elvie and Elvie Stride, Lansinoh, and more. Note: not compatible with 27–28 mm shields.

What’s included

• 16 silicone flange inserts (15/16/17/18/19/20/21/22 mm)
• free nipple measurement card to help you pick the perfect size
• complimentary cleaning brush for easy maintenance

Care and replacement

Made from BPA-free transparent silicone. Clean before use with water and mild soap; sanitize with steam, boiling water, or microwave steam bags. To maintain fit and hygiene, replace inserts every 1 to 2 months.

Choosing the right size

If you are unsure, start with the 16-pack to explore multiple sizes. Nipples can vary during different breastfeeding stages, so having a range helps you adapt as needed. Use the measurement card to compare before and after pumping for the most comfortable fit.
