MaymomPump Parts Compatible with Spectra S2 S1 Replacement Kit for Spectra Pump Parts 24 mm Flange Duckbill Valve Tube Bottle Backflow Protector, Not Original S2 S1 Accessories

The media could not be loaded. I cannot recommend this product enough. I've had issues with pumping, and after visiting a lactation consultant, she measured me for the correct size flange. If you're reading this and experiencing difficulties with pumping, I encourage you to get sized again to ensure you're using the right size. The hospital initially sized me, but I found that I needed a different size since then.The lactation consultant specifically recommended this brand to me, and I saw immediate results after using the correct size. My side that previously produced less went from an average of 2 ounces to a full 6 ounces in just one session. That’s just from one side! In total, I pumped a successful 16 ounces with this pump (my other side is overproducing). I attribute all this improvement to using the correct sized flanges.This product is fantastic because I didn’t need to use inserts or attachments to fit my Spectra. While other brands offer similar products, this one works perfectly with my Spectra right out of the box. It also reduces the number of dishes I have to wash, which is a significant benefit when you're pumping. I can't praise this product enough and am considering buying another set so I can get through a full workday without needing to wash anything in between. I never want to be without it, and I’m done with other brands' inserts!

I bought these Maymom parts as a backup set, and they’ve now become my main set. They fit my Spectra pump perfectly—tight seals, no weird squeals, and strong suction. The plastic feels sturdy, not flimsy like some knockoffs. It even comes with extras, which is perfect when I’m too tired to wash immediately. If your original parts are worn out or mysteriously vanished into the dishwasher abyss, these are a solid replacement.

These parts are completely comparable to the Spectra brand. These are just way more for value for your money. Unlike the spectra brand replacement you get parts for both sides. It also comes with two sets of duckbills so when it’s time to replace no need to go buy more! It also comes with 2 lids allowing the bottles to be used for storage! The lids are compatible with Phillips Avent bottles and come with an O ring making bottles leak free! Definitely recommend these over “name brand”!

These work great with my spectra s2! The parts are interchangeable with the original pump kit and are great quality. The bottles hold a bit less but otherwise they are great!

I have the Spectra S2 and these parts are even better than the spectra originals! I use a 15mm flange, and being able to purchase that size and not have to wash a million inserts is phenomenal. I pump at work but have no place to wash my stuff in between pump sessions, so I drag 3 sets of pump parts to work each day. These are much cheaper, better quality, and fit more compactly in my bag than the spectra original parts. Super grateful to have found this brand! The gradients on the bottles are very easy to read and have not worn off after lots of washing a steam sterilizing. The bottles also have a nice wide base so I never worry about tipping them over when I'm unhooking everything. Love them!

Great affordable dupe that is compatible with the spectra s1 pump parts! I like the size of the bottles- they are shorter than the actual s1 bottles but they fit about 5 oz if you pass the top line but convenient for when I’m not too full. I mix and match the accessories with the actual s1 parts and have had no issues!Just be careful when tighten the bottle to the flange, I find there is no perfect seal. Could be a defect with mine but this also happens with the spectra bottles as well.

I got these parts earlier this week because my back flow piece broke in my breast shield. While there are some differences when comparing to Spectra- these parts do fit and work just like the spectra parts- the size “seemed” larger in the shaft of the breast shield, and is slightly longer, but it fits and works while pumping the same! The parts come with detailed instructions and “o” rings for non leak proof seals when attaching to spectra parts! Im very happy with my choice!

These pump replacement parts work great with my Spectra! This is my 4th time buying this kit to keep my pump parts up to date and I have no complaints! This is the only pump part replacement kit I’ll be buying for my Spectra.
