When it comes to wearable, hands-free, and wire/cord-free portable breast pumps, there are only a few options and Elvie is one of them.
The Elvie is available as a single or double pump option and comes standard with a 24 mm and 28 mm flange with the option of purchasing a 21 mm flange directly from Elvie. Each flange has a size guide on the bottom to help you align your nipples properly but if you already know you need a smaller size, you end up having to find some inserts that will work within the larger flanges.
Because of the way the suction mechanisms work with the Elvie pump, the insert you choose must fit just right or be trimmed down to avoid blocking the holes on the Elvie flange which allow for suction.
This is where some hacks come in!
Enter Legendairy Milk silicone breast shields/flanges (that come with our collection cups or separately) to save the day!
The 24 mm Legendairy Milk silicone flange can fit into the 28 mm Elvie flange without blocking the flange’s air holes. You can then add your inserts to the 24 mm flange to get the diameter you need and provide the length that may be needed for longer or excessively elastic nipples.
The fit is a bit tight, so it does require some wiggling and pressure to get the Legendairy 24 mm silicone flange into the Elvie 28 mm hard flange, but once that is securely in, you can add your inserts into the Legendairy flange. You may need to do a U fold or “tulip” fold (anyone familiar with reusable menstrual cups? That’s the same fold you would use) and then flatten out the folds so that you have a smooth tunnel transition.
It’s also important to note that the Legendairy flange will not sit flush with the Elvie flange, but there is enough stability for the pump to comfortably sit against your breast/chest and within your bra to provide you a comfortable, hands-free, pumping session.
The Legendairy Milk inserts work well in this setup also! You may find yourself needing to do the U fold or “tulip” fold mentioned above to get the insert in comfortably but once you’ve smoothed everything out, you’re good to go!
Statistically many pumpers need even smaller flange sizes than 19 mm, which is why we now offer sizes 15mm, 17mm, 19mm and 21mm.

Hi. I need a hack for 15mm. Will a Maymom 15mm insert work with the Legendary 24mm insert plus Elvie hard 28mm flange? Any other suggestion to get to a 15mm?

Legendairy Milk replied:
Great question! The Maymom inserts are compatible with the Legendairy flange, so using the 15 mm Maymom inside the 24 mm Legendairy Milk flange (inside the 28 mm Elvie flange) is compatible! 🙌
Hi- I am a 19 flange size and have the 21 breast shield on the Elvie original. Can I use the 19 mm insert on the 21 mm breast shield?

Legendairy Milk replied:
The 19 mm insert is compatible with most 24/25 mm breast shields. Unfortunately, the 21 mm breast shields are too small for the 19 mm insert to fit.
Does this hack work with the Elvie Stride also? I am a 19mm flange and just got a new stride and want to get the right flanges?
Hi! I use the 21mm with elvie but was sized at a 16. Do I use the 28 mm instead to add your 24mm insert? Then add the 16?

Legendairy Milk replied:
Great question! To use a 16 mm Insert, you will still need to use the 24 mm Legendairy Milk flange inside the 28 mm Elvie flange. Once the 24 mm Legendairy Milk flange is in place, you can insert the 16 mm Insert. ❤️
I am a 21mm, can I use the 21mm shield with the 28mm Elvie shield?

Legendairy Milk replied:
Great question! The 21mm BREAST SHIELD will work just as well as the other SIlicone Collection Cup breast shields in the 28mm Elvie.
If you would like to use the 21mm INSERT, you will still need the 24mm breast shield to use it with the Elvie.
