MaymomDuckbill Valves for Spectra. Designed for Spectra S1 Spectra S2 Spectra 9 Plus Spectra Dew 350 Not Original Spectra Pump Parts Spectra S2 Accessories Replace Spectra Valve (6 ct White)

I use these on my spectra 2 pump and they fit perfect. Little did I know I was supposed to change these every three weeks, the suction is so much better and I get much more milk now when I pump. I love that it comes with 6 so I don’t have to keep buying them frequently.

I've looked at a few of these to replace parts on the spectra breast pump my wife is using and these are the best alternative to the brand product in terms of quality and price.They seem a bit thicker and less flexible than the original parts, but it hasn't made a difference in the pump performance.Expect some milk to get stuck in it when you turn the pump off.Good product.

I really like these colourful valves so that you can tell which pair is new and which pair is old. they do the job well. however, compared with OEM ones are only $5 after tax per pair including tax if I purchase in Asian countries, the price in North America is much higher! but considering this is Korean brand, it make sense it's expensive here. No complain then!

These are the perfect fit for my spectra 350 electric pump and they work amazing.What a bargain price for 3 pairs

The spectra valves kept falling off after only a month, even with making sure they were clean and dry. These stay on and provide better suction. It’s a pity to have to buy these so soon after but it’s worth the money.
