IVARONAL Flange Inserts 16mm 6pcs – Reduce 24mm Shield to Correct Size for Wearable Breast Pumps

Personalized sizing for comfortable pumping

IVARONAL Flange Inserts are designed to tailor the tunnel size of wearable breast pumps. With a wide range from 12mm to 22mm, you can customize the fit so pumping sessions feel less snug and more comfortable. Many mothers notice changes in nipple appearance during pumping; this product helps you observe and adjust for a better, more relaxed fit without relying on trial-and-error.

What you gain

• Broad size options (12mm–22mm) allow you to reduce a 24mm tunnel to the right size without compromising seal.
• Compatibility with a broad set of brands and models (including Momcozy, Spectra, Medela, and more) helps you find a flexible fit for many setups. Note: not compatible with 27mm shields.
• Soft, food-grade silicone provides a comfortable, skin-friendly touch during pumping, with a snug feel that aims to minimize rubbing or irritation.
• Easy one-step installation and straightforward cleaning after use—wash with warm soapy water; sanitize via steam, boiling water, or microwave bags.

Care and safety

• Always inspect the inserts and replace when deformed or yellowed to maintain proper fit.
• These inserts are BPA-free, odorless, and designed to be gentle on skin while supporting efficient pumping sessions.

While results can vary, some users report improved comfort and a more natural pumping rhythm when using properly sized inserts. They are designed to support your routine rather than guarantee outcomes.
