Willow® 3.0 Flange Set (2-pack)


Our breast pump flanges come in 3 sizes so you can find a fit that's comfortable and optimizes output. If you measure smaller than 21mm, choose our 24mm flanges — they're compatible with sizing inserts.

Exclusively for use with Willow 3.0 spill-proof breast milk storage bags.

Did you know: you should replace pump parts every three months for optimal performance. Normal wear and tear can impact suction and output! Having extras on hand is helpful in the event that you lose a part, too.
