Quick answer
Thrive flange inserts help you get a better fit with your PowerPump set or wearable cup flanges, improving comfort and milk flow. Keep a spare set on hand for pumping away from home.
Why flange inserts matter for your pump setup
Flange inserts reduce the internal diameter of standard flanges, giving you a snugger seal without buying new flanges. This can help prevent nipple rubbing and improve suction efficiency.
Thrive flange inserts are designed to work with both the PowerPump set and wearable cup flanges, so one size option fits multiple pump styles. That means less guesswork when you switch between pumps.
When to buy spare flange inserts
Flange inserts wear over time, especially with frequent use and washing. Having a spare set means you always have clean parts ready, whether you're pumping at work, traveling, or just need a quick swap during a late-night session.
The Thrive Flange Inserts for PowerPump Set & Wearable Cup Flanges come at a practical price point, making it easy to stock up without overspending.
How to choose the right flange inserts
- Check your current flange size: Measure your nipple diameter (not the areola) using a sizing card or ruler. Your flange insert should be 1-2 mm larger than your nipple measurement for a comfortable fit.
- Match inserts to your pump type: Thrive flange inserts fit both PowerPump flanges and wearable cup flanges. Confirm your pump model before buying, and choose the insert size that matches your measurement. If you use both pump types, one set of inserts can work for both — check compatibility first.
- Decide how many sets to buy: Start with one set for your primary pump. Add a second set if you pump away from home, share a pump, or want a backup for when parts are drying. Buying two sets at once saves shipping hassle and ensures you always have clean inserts ready.
