Dr. Brown's CustomflowTM 이중 전동 유축기 교체 부품 키트

Swapping out the old membranes and duckbills with this kit made my pump feel brand new again, and the connectors fit perfectly onto my existing bottles. The two of everything means I can prep a full pump session without stopping to wash parts mid-day.

I was worried about compatibility when ordering replacement parts, but these connectors and valves clicked into place perfectly with my existing setup. Having two complete sets of membranes, caps, and duckbills in one kit means I always have a spare ready when one set needs washing.

The duckbill valves are the reason I keep coming back—they fit perfectly and make the whole pump session feel airtight again. Having two of everything in the kit means I can wash one set while the other’s in use, which has honestly saved my sanity during late-night pumping.
