Key compatibility and range

The flange is designed to work with a variety of Spectra models including S1, S2, 9 Plus, and Synergy Gold. It also pairs with Motif Luna and Ameda Mya pumps, expanding your options for expression or feeding sessions while you test how different bottles feel in your hand and at the pump.

Bottle and part compatibility

Beyond the pump, this flange can connect with Spectra wide-mouth bottles, AVENT bottles, and Momstouch wide-mouth bottles. It is compatible with most other wide-mouth bottles, offering flexibility in daily use when you juggle bottles at home or away.
