How to choose the right size of breastshields for you?

The inner diameter of the breastshield (B) should be 1-2 mm larger than the diameter of your nipple (N) AFTER a pumping session or 3-5 mm BEFORE a pumping session.  You should be able to see free movement of your nipple during pumping and there should be little or no suction of the areola into the tunnel of the breastshield.


When it comes to pumping comfort, every millimeter counts.  That is why we design a series of breastshields of small increment sizes. Maymom one-piece breastshields are available in many different sizes (refer to dropdown selection for range of available sizes) to fit the majority of breast pumping mothers.


How to measure the diameter your nipple?

Download the nipple caliper file, print it out, cut through the red line, fold along the green dots then you have made yourself a nipple diameter measuring tool!  See below for the finished ruler.

Customer Questions
Can thsi fit pigeon wide neck bottles?

This product is meant to fit Spectra wide-neck bottles. Spectra wide-neck bottles has similar width as Pigeon wide-neck bottles, but threading may be slightly different.  It would fit but screwing on may not be 100% perfect and secure.

Does this come in a pair or only one piece per order

As per product description, you will receive one piece.

Is this compatible with S1+ ?

Yes, it is.

Hi, Can I chk what is this difference between this and the 2 pc design?

The 1 piece design means the product is made as 1 whole piece. Maymom Wide-Neck Flange for Spectra/Medela (2-piece Design) with Valve & Membrane, 1pk: 2 piece design means the product is made from 2 pieces, whereby the flange and the connector...

Hi, good day!I have a Spectra S1 machine handed down with no accessories.May I check, beside getting this set, i do need to buy the back flow protector and tubings right?So sorry as I am very new to this. Thank you very much for your assistance! Cheers! :)

If you are pumping double-side, please ensure you have the following: 2 x Flange 2 x Backflow protector & membranes & valves 2 x Tubing 2 x Milk Bottle

Hi can I use the wide to standard wide neck adapter on this so I can fix my standard neck bottle on this flange.?

If you are pumping into standard-neck bottle, you are better of using this product Maymom Breastshield for Spectra with Valve & Membrane, 1pk (8 sizes, 15-36mm) (click here). It allows you to pump straight into a standard-neck bottle, without...

Hi do you separately sell the non-duckbill valves and membranes?

You can actually use this as well: Maymom Replacement Valves (2x) & Membranes (4x) for Medela Breastpumps (click here) This valve & membrane should fit Maymom Wide-Neck flange.

Is this compatible with Hegen bottle? (With hegen adapter)

Yes, it is. For Hegen adapter, please use Hegen PCTO™ Wide Neck Bottle Adapters (2-pack) (click here).

Is this compatible with cimilre s3 pump and pigeon wide neck bottles?

It is not compatible with Cimilre S3 pump, only Medela/Spectra pumps. Width-wise it fits Pigeon wide-neck bottles, but thread-wise it may not. 

Is this compatible with avent single electric pump? Model scf 332?

Unfortunately, this flange can only connect to Spectra and Medela pumps.

Can this fit medela symphony?

Yes, it can.

2 Questions;1. Does this fit the Dr. Brown's Wide Neck 5oz glass bottle2. Can we use our existing Medela PISA valves and membranes with this flange?

No, it does not fit Dr Brown Wide Neck glass bottle. We have not tested Medela valves with this Maymom flange, therefore we are unable to promise the compatibility.

Do you have 17mm flanges for wide neck bottles?

Not at the moment. For now we have smallest 15mm: Maymom Soldered Flange for Spectra/Medela with Valve & Membrane (Wide-Neck), 1pk (click here)

Hi! Is this one flange or one set of 2 in 1 pack?

This is 1 flange only.

HI, does the Mamymom Wide Neck Flange (1pc design) come with 15mm and 17mm ones? Thanks

You can try Maymom Soldered Flange for Spectra/Medela with Valve & Membrane (Wide-Neck), 1pk (5 Sizes) (click here). It's the exact same product (just that it's a 2 piece soldered flange) and it comes in 15 mm.
