Nenesupply 17mm Flange Insert – 24mm to 17mm Reduction for Elvie, Medela, Willow & More

Meet the Nenesupply 17mm Flange Inserts—a compact, soft silicone solution designed to adapt 24mm flanges to a smaller opening. This 2-pack helps you customize fit with brands like Elvie, Medela, Spectra, Willow, Momcozy, and Motif Luna, letting you explore comfort without replacing your entire flange kit. The inserts slide neatly inside the 24mm flange, reducing the opening to 17mm while preserving a strong seal.

Designed for broad compatibility

Because pump configurations vary, these inserts are built to work with most 24mm flanges across popular models. They’re compatible with Elvie flange parts and Willow parts, and work with Medela PersonalFit Flex and Freestyle Hands-Free, as well as Momcozy, Spectra, and Motif Luna styles. Note that performance depends on your current flange and pump combination.

• Brands included in the compatibility scope: Elvie, Elvie Stride, Momcozy, Medela PersonalFit Flex/Freestyle Hands-Free, Spectra, Willow, Willow Go, Motif Luna.
• Available sizes beyond 17mm: 15mm, 19mm, 21mm to broaden your fit options.
• Material: soft silicone for a comfortable feel against the skin and a gentle pump experience.

Key benefits you may notice

Embracing a 17mm opening can help some users achieve a snug fit that supports a more controlled pump feel. The inserts feature embedded sealing circles to help maintain a full seal as you express, and the soft silicone edge reduces irritation at the flange rim. They’re designed to reduce the funnel opening without altering the overall suction apparatus.

• Comfort-focused design: softer silicone and a smaller opening for potentially gentler sessions.
• Seal-preserving details: embedded sealing circles aimed at maintaining a reliable seal.
• Efficiency through fit: correct flange sizing can contribute to an efficient pumping experience when paired with compatible pumps.

How to use and care

Installation is quick and simple: align the insert with your 24mm flange and push in. Removal is just as easy, letting you switch sizes on the fly. These inserts are dishwasher-safe on the top rack, BPA and DEHP free, and comply with EU and USA materials regulations. Independent lab testing supports their safety claims for materials that contact food.
