19mm Oval Flange Pump Parts for S1 S2 9 Plus Breast Pump, Replacement 19 mm Breast Shield/Duckbill Valves/Backflow Protector/Silicone Tubing

Works like a charm! And I actually like this set up (where the parts are detachable) way more than what came with the pump originally.

Perfect set for spectra with the added bonus of being able to fit any Mandela flanges if needed on it

No issues with fittment on my Spectra S2 (and thus shouldn't have any issues with an S1 since they are the same pump with different power sources). The key pieces here are the duckbills, tubing, and diaphragms; I didn't really need the extra flanges, but I suppose they're nice to have around just in case. Overall a replacement set that works and meets my needs, at a lower cost that OEM parts!

Needed a different size, but good quality

These are great, there's nothing worse late at night than needing to clean your pumping equipment because it's the only option for you. These backups allow us to cycle through spares and do a large clean in the morning. Plus they work great. The flanges are sized better than the stock Spectra and have soft silicone where they meet the skin. This allows for a better fit and they can be disassembled even better than stock to allow easier cleaning. Having all the other parts is also hugely helpful. The white vacuum covers are great to have extras of and they have a tab that allows you to remove them without damaging the main seal. It's great to have spares on hand!

I got the flanges , washed them and put them in the sterilizer only for them to melt and completely lose shape.

Love these sets for my lacteck flanges. While the flanges this comes with are nice and comfortable, I prefer silicone. The other parts work well and last quite some time. I exclusively pump and haven’t had to change these out after a month so far.

Had been using my spectra breast pump for a while and last week I thought I didn’t have any milk anymore because I was only able to pump half the amount of milk that I usually pumped. I ordered this and it fixed my issue immediately. I guess it was probably one of the valves or tube that had a defect that led to my ineffective pumping. After switching to the new replacement valves, my milk supply came back fully. Great product, works as described. This is the 19mm flange pump and it is less painful than my previous 28 mm flange pump. Will probably stay with the 19mm from now on.
