Review on Maymom Pump Parts For Spectra S2 Spectra S1 Spectra 9 Plus Breastpump Not Original Spectra Pump Parts Replace Spectra S2 Accessories And Spectra Flange. Inc Flange Backflow Protector Tubing (21Mm) by Ben Jacobson

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.
