eufy Original Duckbill Valves (4-Pack) for Wearable Breast Pump E10/E20/S1/S1 Pro, Leak-Proof and Dust-Proof Breast Pump Replacement Parts

Super pleased with my purchase. I bought these to replace the original ones that came with my pump. I like these even more & they feel more durable. Would definitely recommend the overall Eufy pump. I have the S1.

Work just like the original ones

I've ran into a lot of replacement parts that don't quite fit, but these work perfectly with my S1. I replaceme them every month and continue to have great output.

What else can I say, they're exactly what I needed to replace my eufy E20 duckbill valves. All are in good shape and fit in my pumps like the original ones. Sturdy!

These little guys are super easy to break and was so sad when I found my original one ripped. I was happy to find that amazon had the original parts and for a great deal with multiple quantity options.

These replacement parts for my Eufy wearable pump were exactly what I needed. They fit perfectly, work just like the original pieces, and restored the suction back to full strength. It’s so nice having extra parts on hand so I’m not constantly washing the same ones throughout the day. The quality feels really solid, they’re easy to assemble and clean, and they’ve made my pumping routine so much more convenient. Definitely worth it for any Eufy wearable pump user! 🍼✨

I enjoyed this! I was nervous to purchase on Amazon because some of the Facebook members on Eufy said some of the products bought on Amazon decreased their supply, but these worked perfectly for me!

These inserts are the perfect addition to my Eufy pumps. They make pumping so much more comfortable!
