Adaptable flange inserts for a personalized pumping fit

Meet the Nuliie 8pcs silicone flange inserts. The 15mm inserts are designed to adapt standard 24mm shield sizes to a snug, comfortable fit. The soft silicone edge feels gentle against skin and moves with you as you pump, creating a smoother rhythm without harsh pressure. Made from food-grade liquid silicone and BPA-free, these inserts are reusable and built for everyday use in busy mom life.

What you get and how to use

• 8 pieces in 15mm size that fit most 24mm shields, reducing the tunnel to a comfortable fit
• Free nipple measurement ruler to help you choose the best match for your stage
• Cleaning brush included and dishwasher-safe cleaning options for quick routines
• Size variety reminder that nipple size can vary across breastfeeding stages

Note not compatible with 27–28mm shields. Real-life scenarios vary, but many moms report a feeling of improved seal and calmer pumping sessions with a better fit. These inserts are meant to support a smoother pumping experience and may help optimize your routine, depending on your setup and body.

Why this accessory may matter

The tactile softness of the silicone, combined with a precise 15mm width, offers a gentle transition inside the shield. The result is a potential combination of comfort and efficiency during pumping, especially for those navigating shield size limitations. While outcomes differ, users often describe a more relaxed fit and a steadier pumping cadence when using appropriately sized inserts.

Care, safety, and replacements

• Crafted from BPA-free food-grade silicone that’s designed for repeated use
• Dishwasher-safe for easy sanitizing between sessions
• Rinse after each use and wash with mild soap as part of routine care
• Replace every two months to maintain comfort and performance

Choosing the right size and staying prepared

If you’re unsure, start with the 15mm inserts for a 24mm shield and adjust as needed. Keep a spare pack handy for growing needs, and use the included ruler to compare the fit before and after pumping. This setup aims to support a comfortable pumping routine without making guarantees about outcomes.
