IVARONAL 8pcs Flange Insert 18mm – Compatible with Momcozy, Spectra, Medela & More

Overview

Discover the IVARONAL 8pcs Flange Insert set, an 18mm silicone solution designed to pair with a wide range of wearable breast pumps. Built for versatility, these inserts work with popular models from Momcozy (Air1, W1, M9, M6, M5, S12 Pro, V1 Pro, V2 Pro) as well as brands like Spectra, Medela, Eufy, Lansinoh, Elvie, and MOMMED. The soft, food-grade silicone aims to provide a comfortable, snug fit that helps you focus on your routine rather than equipment adjustments.

Whether you’re adjusting to a new pump, changing stages, or experimenting with fit, this set gives you options without sacrificing comfort. While results can vary, the design emphasizes smoother expression and a more consistent seal, enabling a smoother pumping experience and potentially more efficient use of your time. It’s about offering possibilities, not guarantees, and letting you choose what feels right for you and your body.

Why this matters

Choosing the right flange size can influence comfort and alignment during pumping. The 18mm size in this set targets common needs across several major pumps, with a soft texture that feels gentle against the skin. By helping to align the shield with your nipple path, the inserts may reduce awkward pressure points and support a calmer pumping session.

• Broad compatibility across Momcozy, Spectra, Medela, Eufy, Lansinoh, Elvie, and more.
• Soft, skin-friendly silicone designed to feel comfortable during longer pumping sessions.

Size variety and fit you can grow with

The set covers a wide size range (13–22mm) with 10 distinct options, including 13/14/15/16/17/18/19/20/21/22mm. An included nipple measuring tool helps you quickly identify the best fit for different moments, so you can adapt as needs change throughout your breastfeeding journey.

• Wide range to accommodate evolving comfort and workflow.
• Measuring tool supports quick, on-the-spot sizing decisions.

Safe care and replacement guidance

The inserts are made from BPA-free, food-grade silicone, delivering a soft touch while staying durable with regular use. They’re easy to sterilize and clean between sessions, helping you maintain hygiene with simple routines. For optimal performance, consider replacing every two months, depending on use and care.

• Sterilize via steam, boiling water, or microwave steam bags; wash with mild soap and water.
• Rinse well, air-dry, and replace roughly every two months to maintain fit and function.
