FRUSSONIA Flange Inserts 17mm 6PCS – 24mm Flange Compatibility for Momcozy, Spectra, Medela, Elvie & More

Enhance your pumping experience with FRUSSONIA 17mm flange inserts

In the world of breast pumping, fit matters. The FRUSSONIA Flange Inserts in 17mm create a smaller, more tailored tunnel inside a standard 24mm shield, designed to align with a variety of pumping styles. The mid-weight silicone feels cool against skin and has a firm but gentle feel that supports a steady rhythm during session time.

The design features a thicker wall and a shorter bottom, which together help establish a tight seal and can help maintain suction without requiring extra effort. This combination can minimize leak points and help keep air where it should be—inside the system—so your milk-expressing moments feel more controlled and predictable.

What to expect when you try the 17mm insert

• A snug, comfortable seal that may reduce air escape and help sustain a steady pump rhythm.
• Compatibility across popular brands, including Momcozy, Spectra, Medela, Elvie, and Lansinoh 24mm flanges.
• Flexible use with a selection of sizes to find your best fit, especially if current flange feels tight or rubs.

Why choose the 17mm option

• Precise fit can translate to smoother pumping sessions and potentially better milk flow response.
• Silicone is BPA-free and food-grade, designed for repeated handling and cleaning.
• Replacing regularly (every 1–2 months) supports hygiene and consistent performance.
• Included six inserts ensure you have a steady supply for daily use and backups.

Care, maintenance, and sizing guidance

• Clean after each use with warm soapy water; for deeper cleaning, heat ≤100°C for 5–10 minutes.
• If unsure about size, consider the 8-pack option with two of each of four sizes to compare.
• Store in a clean, dry place to prolong silicone life and maintain problem-free pumping sessions.

Materials and safety are central to FRUSSONIA’s approach: the 17mm inserts are BPA-free and made from food-grade silicone, designed to feel soft yet resilient during repeated use. While individual results vary, many users report a more confident seal and a calmer pumping rhythm when a better-fitting insert is used. Think of these inserts as a practical accessory to expand your pump’s fit options, rather than a guarantee of outcomes.
