The Gem Silicone Flanges are soft silicone inserts that adjust the fit of your Gem Pump breast shield to suit your nipple size. Getting the flange size right is one of the details that makes the biggest difference when you're expressing, and these give you a way to fine-tune the fit without changing your whole setup. They're available in three sizes — 18 mm, 20 mm and 22 mm — so you can match the size to your body.
A well-fitting breast shield keeps pumping more comfortable and helps you express more of the milk that's available to you. If your current shield feels too roomy or the seal isn't quite right, stepping down to a smaller silicone flange can help you find a snugger, more comfortable fit.
Why fit matters
Flange sizing isn't something you can reliably guess from bra size — it comes down to your nipple diameter, and the right size can make expressing noticeably more comfortable. Made from soft, food-grade silicone, these flanges are gentle against the skin and designed to cushion the seal within the Gem Pump breast shield.
