The 3D Soft Silicone Cushion Flange – 17mm is a factory-original replacement shield engineered to enhance comfort and milk expression efficiency for BabyWombWorld electric breast pumps.  This cushion uses advanced 3D compression technology to rhythmically expand and contract, mimicking a baby’s natural latch to optimize milk let-down without causing painful friction.

  • 3D Cushion Technology: Provides dynamic compression rather than static suction, stimulating a more natural and comfortable milk flow.
  • Medical-Grade Silicone: Crafted from durable, velvety-textured silicone that is gentle on sensitive skin and resistant to discoloration.
  • Leak-Free Seal: High-tensile elastic molding ensures a tight fit onto the pump collection kit, preventing pressure drops or air leaks.
  • Customizable Fit: Available in multiple sizes (21mm, 25mm, and 29mm) to accommodate different nipple profiles and ensure maximum comfort.
  • Safe Material: 100% free from BPA, phthalates, and synthetic toxins to keep expressed milk pure and uncontaminated.
  • Easy Sterilization: Designed to withstand steam, boiling water, and standard sterilization methods for safe, hygienic use.

How do I determine the correct flange size?
Sizing is based on the diameter of your nipple base after a pumping session, not your bra size. If you feel pinching or rubbing against the tunnel walls, you may need to step up or down in size to allow the nipple room to expand safely.

How often should I replace these flanges?
For daily pumpers, it is recommended to replace these silicone cushions every 3 to 6 months. Constant motor stretching and heat sterilization will eventually degrade the structural compression strength of the silicone.

How do I sterilize the flange?
Wash thoroughly with mild, baby-safe soap after every use. You can sterilize them using an electric steam sterilizer, by boiling in water for 3 to 5 minutes, or using a microwave sterilization bag. Avoid abrasive brushes to prevent scratching the surface.

Can I use this with other breast pump brands?
No. These cushions are custom-engineered with specific seating grooves tailored exclusively for BabyWombWorld electric breast pump collection kits. Using them with other brands will likely compromise the vacuum seal and degrade suction performance.

Is this item returnable if the size is incorrect?
Due to medical and sanitary regulations, this is a personal-wear item and cannot be returned or exchanged if ordered in the wrong size. Please measure your nipple diameter carefully before finalizing your checkout.
