Dr. Brown's 搾乳器用 交換用ダックビルバルブ 2個入り

These are the only valves that keep my pump working like it should, suction stays strong and consistent each session. I ordered a 2-pack and it’s been a lifesaver for morning pumping when I’m rushing.

The valve slid in without any fuss, and that unique design really restored the suction like it was day one. Two in the pack means I have a spare ready when the next wear-out happens.

My pump’s suction was getting weak, but swapping in these duckbill valves fixed it right away—the seal is tight and they slide in easily. I grabbed the 2-pack so I always have a spare on hand for the manual pump, which is a lifesaver during late-night sessions.
