Product details

These silicone rings are maintenance parts for the original S9/S12 wearable cup system. Seals are small components, but stretching, damage or deformation can reduce the airtight fit the pump needs to work consistently. Replacing the ring is therefore a more economical first step than replacing the complete pump when the rest of the system is still in good condition.

What parents appreciate

  • The practical positive for genuine seals is restoring fit while reusing the motor and collection hardware.
  • Because Momcozy has changed its wearable-pump architecture several times, generation-specific compatibility is more important than visual similarity.
