Nuliie 8Pcs Silicone Flange Inserts – 14/16/18/20mm Sizing Kit for 24mm Pumps

Tailor-made comfort for your pumping routine

Meet the Nuliie 8Pcs Silicone Flange Inserts, a sizing kit designed to adapt your 24mm wearable breast pump to your unique shape. The eight inserts span 14, 16, 18, and 20 millimeters, giving you flexible options to refine fit as your needs evolve. Note: this kit is not compatible with 27–28mm shields.

Why the right fit matters

The right flange size can influence how comfortably you pump and how smoothly milk flow can feel during a session. With multiple sizes in one kit, you have the freedom to experiment and discover a fit that best suits your body and routine without changing your pump hardware.

Quality, safety, and easy care

Crafted from food-grade liquid silicone, these inserts are BPA-free and dishwasher safe, making cleaning simple after every use. The soft, flexible material is designed to slip into your shield to adjust the nipple tunnel diameter, potentially reducing tension and enhancing everyday pumping comfort.

• Compatibility: fits most 24mm wearable pumps to tailor shield size for a better fit.
• Safety & care: BPA-free silicone; dishwasher safe; clean promptly after each session; consider a regular replacement every 2 months.
• Extras: complimentary nipple measurement ruler included; 24/7 customer service; free replacement if sizing isn’t right.

What you get and practical use

The eight-piece set includes four sizes—14, 16, 18, and 20 mm—providing a practical path to find the most comfortable shield fit across your pumping routine. The compact, soft inserts are designed for quick swaps, helping you adapt as nipple size or comfort preference changes through different breastfeeding stages.

• Real-world use: experiment with sizes to support a smoother pumping rhythm and potential comfort gains.
• Maintenance: keep the inserts clean and ready; they’re durable and easy to care for with regular use.

Supportive extras and sizing transparency

Alongside the inserts, Nuliie offers a free nipple measurement ruler to help you compare sizes before and after pumping. The brand also provides responsive support to help with sizing questions. Packaging may vary between new or old versions, but the product inside remains the same high quality.
