Vaihtoläppäventtiili Expression-kuppeihin

These valves fit the cups perfectly and the improved seal makes a noticeable difference in how steadily the milk flows. I ordered two sets and swapping out the old ones took less than a minute each.

I was getting so frustrated with slow letdowns until I swapped in these replacement valves—the milk flow is noticeably more consistent now, and they snap into the cups without any wrestling. Each valve feels sturdy enough that I don't dread ordering refills again.

These valves fit perfectly and create a much better seal than the old ones I was using. The suction feels noticeably stronger, so pumping sessions are quicker and there’s no more wasted milk pooling in the flange.
