Finally got around to replacing the old valves on my pump and the suction feels strong again right away. The silicone is flexible but not flimsy, and they sealed perfectly into the collection bottle without any leaks. My last set lasted months, so these two should hold up fine.

These valves fit perfectly and restored the suction on both my pump setups right away. Milk flows cleanly into the bottles without any of the leaking I was dealing with before, and they seem sturdy enough to last through plenty of washing cycles.

My pump is finally working like it should again—the suction is strong and consistent now that I swapped in these silicone valves. They were easy to clean and install, and milk flows straight into my bottles without any annoying backflow.
