Willow Wave Valves Set (4-pack)

The food-grade silicone feels really sturdy, and the one-way seal is noticeably tighter than the old valves I had. My pump sessions have been mess-free ever since I swapped these in, and the 4-pack gives me peace of mind for the next few months.

Installed these in under two minutes and the food-grade silicone feels noticeably sturdier than the originals. The one-way seal holds up even when the pump is tipped sideways, which has saved me from a few messy spills this week.

The food-grade silicone feels reassuringly sturdy compared to the originals, and the one-way flow has been flawless so far. My pump is running quieter and I haven't had a single leak since swapping them out.
