Frequently Asked Questions

Q: Which breast pump brands are these silicone flange inserts compatible with?

A: These breast pump flange inserts are designed to fit most breast pump brands that use 24mm or 27mm detachable shields, including many popular wearable and standard pumps. Always check your pump's shield size before ordering to ensure compatibility.

Q: How do I know which insert size (15mm, 17mm, 19mm, or 21mm) is right for me?

A: The correct insert size depends on your nipple diameter. Measure your nipple (not the areola) in millimetres and select an insert that is 1–3mm larger than your nipple for a comfortable, efficient fit. A lactation consultant can help you determine the right size if you're unsure.

Q: Are these breast pump flange inserts safe for regular use?

A: Yes. These inserts are made from food-grade silicone and are free from BPA, PVC, latex, nitrosamines, and phthalates — making them safe for regular pumping use. They are also washable and reusable, so they are both economical and hygienic.

Q: How do I clean and care for the silicone flange inserts?

A: Simply rinse the inserts with warm, soapy water after each use and allow them to air dry. They can also be sterilised by boiling or using a steam steriliser for added hygiene. Avoid harsh chemicals or abrasive cleaners to preserve the silicone material.
