Maymom Pump Part Compatible with Spectra S1,S2 Spectra 9 Plus Breastpump; Incl Wide Mouth Flange (One flange-18mm Flange) Not Original Spectra Flange; Not Spectra Baby USA Parts

I love that the flanges are true to size, and a little bit wider towards the valve, which I feel helped milk to flow better and faster through the flange. The quality of this was great, I really like that the plastic pieces felt more sturdy than the accessories that my spectra came with by default.I used these with the blue spectra and they were compatible. I really didn't notice a difference between spectra parts and these except for the increase in quality and thickness. I also love that they sell the individual flanges in such a great variety of sizes.Piece of Advice: order slightly larger than you need, then buy cushions/inserts to make the flange more comfortable. No fault of this company, but plastic isn't really comfortable any way you try to do it.

True to size and much easier to use/clean than having to put an insert into the 21 mm flange my Spectra pump came with. Fits the Spectra bottles well.

These flanges are excellent! I bought them to use with my spectra pump as spectra (and most pump manufacturers) do not make flanges this small. This is extremely annoying because most women do not realize that they are using flanges that are way too large and both cause them pain and stifle their milk output.These flanges offer a great way for me to pump more effectively in order to maximize milk output. They are quite comfortable and fit my spectra parts perfectly. Fit is also crucial to ensuring proper suction and effective milk removal so the fact that they fit just as well as the original spectra parts is wonderful. Highly recommend!

Purchased because I needed a size I could not get from the replacement site with my insurance. Worked wonderfully with my Spectra S1 original parts.

If your pump flanges are too big and you're wondering why your sessions feel like medieval torture—these inserts are your fix. The 18mm size helped with suction and comfort, and they fit snugly in my Spectra parts. Easy to clean, too. Sometimes it really is the little things that make pumping suck less.

These fit perfectly on my spectra pump however I feel like they are shaped a little bit different and my breast don’t fit as well into them. It still works but I feel like it could be more effective.

These are my favorite flanges for pumping! I used these for my first child and reordered a new size when I had my second because I love this brand so much! The fit is great and they’re super easy to clean!

Love Maymom products - exactly as advertised. I wish they came in packs of multiples!
