Find your most comfortable fit with the MammaBump Flange Insert Fit Pack, designed specifically for the Luna® Wearable Breast Pump.
Made from soft, flexible, high-grade silicone, each insert fits securely inside the Luna® flange to reduce the tunnel size and create a more comfortable, customised fit for smaller nipple sizes.
The pack includes four sizes:
- 15 mm
- 17 mm
- 19 mm
- 21 mm
Having multiple sizes on hand makes it easier to find the fit that feels right for you — particularly as nipple size can differ between breasts or change throughout your pumping journey.
Simply insert your selected size into the Luna® flange before pumping.
Compatible with: Luna® Wearable Breast Pump
Material: Soft, flexible silicone
Sizes included: 15 mm, 17 mm, 19 mm and 21 mm
For the best pumping experience, use our nipple ruler to measure your nipple size and refer to the Luna® sizing guide before selecting your insert.
Care Instructions
To clean your parts we recommend simply using warm soapy water with a soft cloth or brush. Ensure all parts are properly dry before using your pump.
Breast pump parts are only in contact with breast milk which is sterile, so they don't require sterilising (unless specifically instructed by a medical professional).
Most dishwashers operate at over 100° which can be harmful to your parts. This may cause them to discolour, warp or deteriorate and require replacing fast.

Flange was exactly as advertised
I have 2 pumps to use simultaneously and after waiting for it to get sent to Australia, I only twigged when it arrived that it wasn’t a set of 2. That could be made a bit clearer in the description. But the product itself is great.
It's so comfortable for breastfeeding mom.
Bought these flange inserts and it works great, i could tell the difference using them when pumping! Just a bit tricky to place inside the flange, but other than that im satisfied with the product!

The flange insert fits perfectly in the mamma bump pump and definitely helped the pump to work better for me.
This flange size was perfect
Amazing product with a valid sizes to suit the individual. They work really well.
Good product
Great match
Great product.
These flanges are great and really comfortable! The shipping took a little time but over all they were worth the wait. I paired them with my hands-free wearable Luna pump from mamma bump and they are awesome!
Cheap and effective
Good fit and easy to use.
I have very small nipples and got the 15mm flange. Use it with the Luna and able to pump with no pain and gets lots of milk!
Perfectly fits in the MammaBump pump and also my spectra
Had to purchase flange insert for the Ella model, happy with purchase as now I feel as those I have a better suction around nipple to express
Glad they have these options, I ordered in case but didn't end up needing it.
Perfect size! Suction is so much better!!
I order the 21mm flange insert and it works really well.
