Features & Benefits:
19 mm size
Designed for comfort + performance — The tunnel and funnel are shaped to let the nipple move freely without rubbing tunnel walls or pulling areola tissue in. A well-fitted flange means better drainage, less irritation, and a more comfortable session overall.
BPA/DEHP-free, easy to clean — Built from safe materials you can trust, with streamlined surfaces and minimal crevices to make sterilizing or washing quick and thorough.
Fits Spectra wide-neck systems — Compatible with S1, S2 & 9+ pumps (closed system) and pairs nicely with Spectra wide-neck bottles or other wide-neck setups.
2-pack for backup or convenience — Keep one set at home and one in your pump bag, so when life gets busy you’re always ready.
Who It’s For:
Pumping parents who want to optimize your gear for comfort and output.

Why Choose This Over Generic Flanges:
Not all flanges are created equal. This one is tailored specifically for the Spectra system with size precision, reliable fit, and materials you can count on. Rather than sticking with an ill-fitting “standard” size and compromising comfort or output, choosing the right flange size means better milk removal, less irritation, and more confidence in every pump session. When you’re already doing the hard work of pumping, your gear should just work for you — not against you.
Make your pumping setup work with you, not add to the challenge. Choose the 19 mm Spectra Breastshield 2-Pack and pump smarter.
