Product Highlights & Benefits:
Accurate Fit Adjustment: Reduces the 24 mm nipple tunnel down to 21 mm for a closer fit and greater pumping comfort.
Wide Compatibility: Works with Spectra and Medela 24 mm hard flanges.
Comfort + Performance: A better match between nipple and tunnel can reduce friction, improve suction, and enhance milk flow.
Safe & Easy to Use: Made from BPA-free, food-grade silicone and easy to insert into your existing flange.
These 21 mm flange inserts are great for pumpers who find the standard 24 mm flange too large, whether you’re pumping at home or on the go. Smaller flange openings often help reduce discomfort, minimize nipple movement inside the tunnel, and support a better seal — all of which can contribute to a more efficient pumping experience. Use with compatible Spectra and Medela pumps; simply insert into your existing 24 mm flange and start pumping.
Material: Food-grade, BPA-free silicone
Pack: 1 pair (two inserts — one per side)

Note: This is an aftermarket flange insert designed to adapt your existing flange/shield — it is not an original manufacturer replacement part.
