About Nenesupply 2nd Gen 17mm Flange Inserts

Nenesupply presents its 2nd Generation 17mm flange inserts as a two‑piece silicone solution that adapts larger 24mm flanges to a more compact 17mm size. Designed for compatibility with a wide range of pump brands, these inserts work with 24mm flanges from Elvie, Elvie Stride, Momcozy, Willow, Willow Go, Spectra, Medela, Motif Luna, and more. The kit is sold as a 2‑pack and is offered in multiple inner diameters to suit different comfort needs, including 15, 17, 19, and 21mm options. The goal is a smooth, comfortable fit that aligns with the natural contour of the breast for many users, while maintaining compatibility with existing pump parts and accessories.

Key Benefits and Real‑World Use

In daily use, the right flange size can influence comfort and airflow during pumping sessions. These inserts feature a smooth angle and soft silicone texture to support a gentle, ergonomic feel. A key design detail is embedded sealing circles that help create a complete seal, which can support steady suction and reduce gaps that disrupt the pumping rhythm. To keep you going through busy days, the 2nd Gen design emphasizes quick installation and removal, so you can swap sizes without hassle when needed.
