Maymom Pump Parts Compatible with Spectra S2, Spectra S1, 9 Plus Pump Not Original Spectra Pump Parts Replace Spectra S2 Accessories and Spectra Flange. Inc Flange Backflow Protector Tubing (28mm)

This package contains everything you need for your spectra pump, apart from the collection bottles. This even comes with a pair of duckbill valves, though it might be good to extra valves anyway to ensure continued optimal usage of your pump.

Fits the Spectra S1 Plus well, parts look almost identical to the original.

My friend gifted me a spectra pump so I bought these parts to be able to use it. So far everything works great and all the parts fit perfectly. I've never used the original parts but these seem like what they would be like, I really like the extra long tubes because it allows me to be comfortable on my bed at night without having to hang on the edge. Came with two duckbill membranes which was a great surprise

UPDATED 2/1/19: after a while of using these parts I noticed a dip in supply. I got some Spectra brand backflow valves and I think that was the issue. The Spectra valves have a thicker silicone and a tighter fit. The rest of the parts from Maymom were fine but the thinner silicone didn’t seem to work as well for me.These part fit perfectly with my spectra pump. No issues whatsoever with product quality as I’ve seen in some other products. Maymom is my go-to brand for pump parts.

I needed a quick replacement as I broke a flange for my Spectra2 and was able to get this the next day. It works just as well and came with promotional duckbills as a bonus.
