Nenesupply 15mm Flange Insert – 24mm to 15mm Reduction, Elvie/Medela/Spectra/Willow Compatible

Meet the Nenesupply 15mm Flange Insert

A compact, soft silicone solution designed to broaden your pumping options. This 2-piece set reduces a common 24mm flange to a comfortable 15mm size, offering a snug seal and a more tailored experience without changing your entire flange system.

Designed for broad compatibility, these inserts work with 24mm flanges from Elvie, Elvie Stride, Momcozy, Medela (PersonalFit Flex and Freestyle Hands-Free), Spectra, Willow, Willow Go, Motif Luna, and more. The result is a flexible option that can support a variety of setups across brands, helping you adapt to changing needs without new hardware.

Key compatibility details help you plan your fit: the inserts are available in 15, 17, 19, and 21mm, letting you dial in size based on comfort and routine. Made from soft silicone, they cushion the funnel and support a secure seal while you pump.
