WILLOW WILLOW 3.0 / 360 Leaking Milk

Willow 3.0 FlexTube™ (2-Pack)

The FlexTube is the critical fluidic bridge and vacuum seal for the Milk Bag system. Over time, the internal silicone check valve undergoes material fatigue or accumulates microscopic residue, preventing the valve from maintaining the hermetic seal necessary for 360-degree mobility. This leads to gravitational leakage when the pump is tilted or inverted.

Willow 3.0 Reusable Container

When using the reusable storage option, the integrated duckbill valve and silicone diaphragm within the container assembly are the primary points of failure. If these components become distended or the perimeter gasket loses its compressive seal, the vacuum-assisted containment fails, allowing milk to escape the container's internal chamber.
