21mm Flange Maymom Pump Parts Compatible with Spectra S2 S1 9 Plus Breastpump Not Original Spectra S2 S1 Replacement Pump Parts Accessories, Small Flange

Spectra doesn’t come with the standard flange sizes for me so this set fit the bill to solve my problem. Compatible and interchangeable- it’s handy to have an extra set on hand so you don’t need to clean and sanitize right away.

Haven’t had any issues with it.

Good size bottles these work well and I have been using them for a few months now and they hold up nicely.

I’ve ended up purchasing two sets because you can never have enough extra pump parts 😅 like the durability and quality of these parts. Haven’t had any issues with them.

Bought this to use as an extra pump parts set formy Spectra pump, and use alternately with my Spectra parts. Don’t notice any difference in suction or function. Price is great. There’s a small booklet included to show you how to put together and pull apart all the parts properly so they don’t accidentally break, which is SUPER HELPFUL.. I don’t remember my Spectra pump having something like that. Storage containers’ volume marking are clear and easy to read, but it’s a little difficult to pour the last few drops of milk out due to the shape of the top of the container. One-piece flange is easier to clean than my Medela flanges. Came with 2 white duckbill valves and 2 blue ones; the blue ones are great to help distinguish from my other older set of white ones.. I like to keep the sets separate so that I can replace a set of 2 old valves together. Love that MayMom offers flange sizes that Spectra does not, but 1) I’m still not sure what the best size is for me and 2) doesn’t seem like MayMom offers the in-between flange sizes in all their product bundles. Have not used the tubing or storage caps yet so can’t comment on those.

These replacement parts for my Spectra 1 worked extremely well. I would highly recommend maymom parts to save a little bit of money when replacing old spectra parts.

These work perfect as my second set of parts for the spectra. Good quality and great price. Storage containers are the only part that seem different from the actual spectra brand.

I needed to replace my flanges for my spectra 2 after pumping for four months, but the original parts are soo expensive. I’m glad I found this brand. I personally think they’re better than the spectra original flanges. I had to buy an insert for the old flanges so I ordered the 21 and it’s perfect. I don’t want to say my output has increased, but I am getting a little bit more out of each breast. I used these parts for one whole day then I ordered a whole extra set of this brand! I’m very satisfied!
