Getting flange size right changes everything about pumping comfort, and this Willow® sizing insert set fine-tunes the fit of both the Willow Go™ and Willow® 3.0 pumps without buying whole new flanges.
Inserts adapt the flange opening to your measurement, a small adjustment that pays off in comfort. One set serves either pump model, which simplifies life for households running both. Pack quantities appear in the dropdown below.
