Frequently Asked Questions

Q: What size breast flange insert do I need for my breast pump?

A: The correct size depends on your nipple diameter. You should measure your nipple (not the areola) and choose a flange insert that is 1–3mm larger than your nipple measurement for the best comfort and suction. Available sizes are 13mm, 15mm, 17mm, 19mm, 21mm, 24mm, 25mm, and 26mm.

Q: Is this silicone breast flange insert compatible with my breast pump brand?

A: Yes — this flange insert is designed to be broadly compatible with most major electric and manual breast pump brands. It fits inside your existing breast shield/flange to reduce the nipple tunnel size. We recommend checking your current flange's inner diameter before purchasing to ensure a seamless fit.

Q: How do I clean and sterilize the silicone breast flange insert?

A: The insert is dishwasher-safe and can also be hand-washed with warm soapy water. For sterilization, it can be boiled briefly or cleaned using a steam sterilizer. The durable soft silicone maintains its shape and integrity through regular cleaning cycles.

Q: Is this product safe for use during breastfeeding?

A: Absolutely. The insert is made from soft, medical-grade silicone and is completely free from BPA, PVC, Latex, Nitrosamines, and Phthalates — making it safe for both mom and baby.
