IVARONAL 8pcs Flange Insert 16mm – Compatible with Momcozy, Spectra, Medela & More

Comfort, compatibility, and practical design

Meet IVARONAL’s 8pcs Flange Insert in size 16mm, built to accompany a wide range of popular breast pump brands. This set is designed to enhance your pumping experience by offering a softer touch, a closer skin fit, and a more tailored shield size. By adjusting the shield tunnel to a more suitable dimension, the inserts aim to reduce press points and keep the pumping session comfortable from start to finish.

Designed for flexibility, these inserts work with many mainstream pumps, including Momcozy Air1/W1/M9/M6/M5/S12 Pro/V1 Pro/V2 Pro, Spectra, Medela, eufy, Lansinoh, and Elvie. They fit most 24mm wearable pumps, helping to bring the shield into a more consistent size for a smoother connection between you and your pump. In daily use, this means less fiddling and more focus on the task at hand, whether you’re at home or on the go.

• Compatibility across multiple brands and models for a versatile pumping setup
• Size reduction from 24mm shields to a correct 16mm fit for improved comfort
• Includes an accurate nipple measuring tool to help identify the best size for you

Material choice matters when you’re dealing with frequent use. The inserts are crafted from soft, food-grade silicone that is BPA-free, providing a gentle touch on delicate skin while maintaining a close seal with minimal foreign body sensation. The small, snug fit is designed to support comfortable expression and reduce upset due to pinching or slipping during pumping sessions. While individual results vary, many users appreciate the calm, steady feel of the silicone against the skin as they express milk.

• Soft, BPA-free silicone that’s gentle on skin
• Close-fitting design to promote comfortable expression
• 9 sizes offered (13–22mm) with 16mm included in the set

Convenience and care are simple with IVARONAL. The flange inserts are easy to sterilize using steam, boiling water, or microwave steam bags. After use, wash with mild soap and water, then rinse and air-dry. A routine replacement every two months is suggested to maintain optimal functionality. The set also includes a nipple measuring tool to help you choose the right size as your needs evolve, making it easier to adapt to changing comfort levels over time.

Whether you’re seeking a more comfortable fit, a clearer path to the right size, or a versatile option that works with several brands, this 8-piece flange insert set from IVARONAL is designed with practical use in mind. It’s not a guarantee of a specific outcome, but it offers a thoughtfully engineered option to support your pumping routine according to your unique needs.
