The Horigen Silicone Diaphragm (B4012) is a factory-original, medical-grade replacement component designed specifically for BabyWombWorld and Horigen series electric breast pumps. This flexible silicone membrane acts as the critical “engine” of the pump, creating an airtight vacuum seal while simultaneously serving as a secure backflow protector to prevent milk and moisture from damaging the electronic motor housing.

  • Closed-System Hygienic Barrier: Acts as an absolute physical barrier that prevents milk backflow, protecting the pump motor from liquid damage and cross-contamination.
  • High-Tensile Elasticity: Crafted from premium, resilient silicone that preserves original factory suction strength and rhythmic vacuum speed.
  • Precision Fit: Features a custom-engineered outer rim that snaps flush into the expression collection kit, eliminating micro-air leaks.
  • 100% Medical-Grade Material: Manufactured from food-safe, pure liquid silicone that is completely free from BPA, phthalates, and chemical toxins.
  • System Renewal: An essential replacement part to restore weakened or lagging suction performance caused by stretched or worn diaphragms.

When should I replace the silicone diaphragm?
Replace your diaphragms every 1 to 3 months, depending on your pumping frequency. Signs that it needs immediate replacement include a sudden drop in suction power, longer expression times, or any visible cloudiness, cracks, or tiny splits along the silicone dome.

Can I sterilize this part?
Yes. You can safely sterilize it daily using an electric steam sterilizer, clean boiling water for 3 to 5 minutes, or a specialized microwave sterilization bag. Let it cool completely before re-installing.

What is the best way to clean it?
Wash it after every use in warm, soapy water using mild, baby-safe dish soap. Use only your fingers to gently clean it; never use abrasive brushes or sharp objects, as these can puncture the thin silicone and ruin the vacuum seal.

Is this compatible with other breast pump brands?
No. This part is precision-molded specifically for BabyWombWorld and Horigen pump kits. Using it on other brands will prevent the pod cap from locking correctly and cause air leaks.
