Need a better fit for your Elvie or wearable breast pump? These 14 mm silicone inserts reduce 24 mm hard flanges for a snug, comfortable fit — essential for small nipples or sensitive pumping sessions.

  • Comfort-Focused: Soft silicone insert helps improve comfort, reduce nipple stretching, and minimize pumping-related irritation.

  • Improved Seal & Suction: A closer, more personalized fit can enhance suction efficiency and milk output for those with smaller nipples.

  • Easy to Install & Clean: Simple insertion into existing 24 mm flange; can be removed for cleaning. BPA-free, made for safe breastfeeding use.

Whether you’re new to pumping or optimizing your existing setup, a well-fitting flange can make a huge difference. This silicone flange insert allows you to adapt a standard 24 mm hard flange — commonly included with wearable pumps like Elvie — to a smaller, more comfortable size.

Many people find default flanges too large, which can lead to poor suction, discomfort, or tissue pulling. By inserting this silicone adapter, you can achieve a snug fit, creating a better seal, increasing comfort, and often improving milk expression.

This insert is especially useful for parents with smaller or sensitive nipples, or those who struggle with flange slipping, irritation, or sub-optimal output. It’s a simple, low-cost way to customize your pumping setup without replacing entire flange sets.

With safe, easy-to-clean silicone material and straightforward installation, this product is a smart and practical addition for anyone using an Elvie pump (or other compatible wearable pump).

Material: Food-grade, BPA-free silicone

Compatibility: 24 mm hard flange (Elvie and other wearable pumps)

Purpose: Resize flange opening to smaller diameter for improved comfort and suction

Maintenance: Remove and sterilize/clean between uses

A properly sized flange is not optional — it’s fundamental. Poor flange fit can lead to discomfort, reduced milk flow, or even tissue irritation. These inserts help meet the needs of parents with smaller nipples or those who want to fine-tune their pumping setup without buying brand-new flanges.
