NENESUPPLY 17mm Flange Insert – 24mm to 17mm Conversion for Elvie, Medela, Spectra, Willow & More

Overview

NENESUPPLY 17mm flange insert offers a practical way to tailor flange size without swapping pumps. Crafted from soft silicone, these inserts convert a 24mm flange to a slimmer 17mm profile, helping to align your equipment with your comfort needs while preserving a secure seal during use.

Compatibility and versatility

This set is designed for broad compatibility. It works with 24mm flanges across popular models such as Elvie, Elvie Stride, Medela Personalfit Flex and Freestyle Hands-Free, Spectra, Willow, Willow Go, and Motif Luna. The result is a flexible option that can adapt to multiple devices, allowing you to explore a better fit without purchasing new parts.

• Universal approach to 24mm flange capacity with 17mm sizing
• Available in 15, 17, 19, and 21mm for precise matching

Comfort-focused design

The inserts are made from soft silicone to reduce bulk and enhance comfort during pumping. An embedded sealing circle helps maintain a complete seal, contributing to a steady suction without frequent adjustments.

• Soft silicone for gentle contact with the skin
• Embedded seal helps sustain suction and minimize leaks

Ease of use and care

Installation is straightforward: simply push the insert in or pull it out to switch sizes. Cleaning is convenient as the inserts are top rack dishwasher safe and free from BPA and DEHP. They comply with EU and US regulations for materials that contact food, and independent labs have tested them for quality and safety.

Real-life use may reveal a more comfortable pumping experience when the 17mm profile aligns with your anatomy. This is not a guarantee, but the option can offer a more customized fit for smaller nipple profiles and a snug pump seal when paired with compatible flanges.
