How to Choose the Right Flange Size
For the most comfortable and effective pumping experience, choose a flange size that is 2-4mm larger than your nipple measurement. Here’s a simple guide:
- 11mm nipple size → Recommended flange: 13mm or 15mm
- 15mm nipple size → Recommended flange: 17mm or 19mm
- 20mm nipple size → Recommended flange: 24mm
- 23mm nipple size → Recommended flange: 27mm
If you're unsure about sizing, feel free to reach out to us for guidance—we’re happy to help!

Easy Cleaning & Maintenance
Breast pump parts do not require sterilisation since they only come into contact with sterile breast milk. Frequent exposure to high heat can cause parts to discolour, warp, or deteriorate, leading to the need for more frequent replacements.
Unless advised otherwise by a healthcare professional, we recommend washing with warm soapy water using a soft cloth or brush. Always ensure all parts are fully dry before use.
A Comfortable, Custom Fit for Every Mum
Alva Flange Inserts are crafted from high-grade, flexible silicone, providing a gentle, secure seal that conforms to your breast for a more comfortable pumping experience. Designed to seamlessly attach to your Alva Wearable Breast Pump, these inserts help create a personalised fit to improve both comfort and efficiency.
If you're experiencing discomfort or need a better-fitting flange size, our inserts are the ideal solution to enhance your breast-pumping routine.
