Frequently Asked Questions
Q: How do I know which breast pump this silicone diaphragm is compatible with?
A: These replacement breast pump parts are designed for wearable electric breast pumps. Please compare the dimensions listed above (diaphragm: ~4 cm, seal cover: ~2 cm, bra buckle: ~10 cm) with your existing parts before purchasing to ensure compatibility.
Q: How do I clean and sterilise these silicone breast pump parts?
A: Cleaning is simple — just submerge the parts in boiling water for 3–5 minutes to sterilise. The smooth silicone surface resists residue build-up, making routine cleaning quick and easy. Allow to air dry fully before reassembly.
Q: Are these breast pump parts latex-free and safe for nursing moms?
A: Yes! All parts are made from food-grade, latex-free silicone with no toxic chemicals or added fragrances, making them safe for use by nursing mothers and around infants.
