Flange Accessory Kit

Need a smaller flange than the one that came with your breast pump? Our s let you change the flange itself rather than adding a silicone insert inside a larger tunnel.

Available in 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm and 19mm, these hard plastic flanges are a simple way to create a pumping set-up that better fits your body.

They're also handy if you need a spare pumping kit, want to replace worn pump parts, or want to use a different flange size without replacing your entire pump. Each kit includes

- 1 x hard plastic flange in your chosen size
- 1 x backflow protector
- 1 x duckbill valve

Just add your existing tubing and a compatible bottle. Compatibility

These kits work with most breast pumps that use standard external tubing and are designed to fit standard wide-neck bottles, including bottles commonly used with brands such as Spectra, Milkbar, Avent, Bellema and Pigeon.

They can be a great option for pumps that come with limited flange sizing, allowing you to use a smaller hard plastic flange while continuing to use your existing pump motor.

Please note: These kits are not compatible with the Unimom Forte. The Forte's pressure can cause the backflow protector membrane to pop out during pumping. Not sure which size you need?

Flange sizing isn't simply about measuring your nipple and adding a set number of millimetres. A good fit should feel comfortable, allow your nipple to move freely within the tunnel without becoming stuck, and support effective milk removal.

If you're unsure about your fit, Flow & Flourish also offers flange fitting support to help you find the size and shape that works for your body.
