• Better fit for many users with nipple diameters around 19–21 mm

Care, maintenance, and replacement

Cleaning is straightforward: rinse, sanitize with steam, boil, or use microwave-steam bags. For continued performance, consider replacing the flange every two to three months to maintain optimal function.

Compatibility notes

This is a replacement part and not the original Spectra flange. Some wide-mouth bottle brands may not fit; verify compatibility with your bottle brands before use. It works with Spectra backflow protector systems as shown in the listing to support your pumping workflow.
