About this item
Highlights
- Reusable Flanges are clear colored for nipple visibility and alignment for easy placement and fast assembly to ensure effective suction. Flanges are reusable, but should be replaced every 3 months for optimal performance.
- Completely mobile and hands-free & easy to assemble – everything fits inside the pump without cords or attachments. This breast feeding accessory gives you the ability to pump directly into Willow Go Reusable Breast Milk Containers and easily transfer to a storage container or bottle when you’re ready to feed.
- To find your perfect size, reference our sizing chart (pictured) to determine your size for optimal pumping experience. Flanges come in three sizes: 21mm, 24mm, and 27mm. In addition, 24mm flanges are compatible with sizing inserts for mamas who measure smaller than 21mm.
- Easy set up, easy clean up with dishwasher-safe parts to clean.
- Exclusively designed to work with the Willow Go Wearable Breast Pump.

These flanges are my favorite!
[This review was collected as part of a promotion.] These flanges are my favorite! I get almost the same output with these as a “primary” pump’s flanges. They are easy to use the Willow inserts for a customized fit. I definitely recommend having an extra set of parts for easy outings.

I purchased the 27MM flange
[This review was collected as part of a promotion.] I purchased the 27MM flange for a better fit. This is more comfortable for me. I wish I could select my flange size when purchasing my pump so it’s not an additional expense considering it came with flanges that do not fit.

In fairness to Willow, this
[This review was collected as part of a promotion.] In fairness to Willow, this review is for the Willow replacement parts as a whole and may not be an issue of the flanges. I've had this pump for less than 4 months and lately I've had issues where near every time I go to reassemble, the flange "pops" off the assembly. I used to be able to get it to stick back in place by pushing it down, wiping it down to ensure no moisture, etc, but lately that hasn't been working and as a result, it sadly renders the entire pumps inoperable. When I search this issue on Google, it seems like this is an issue that others have had. Bummer!
