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

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.

Ordered replacement parts for the pump. Works great.

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! 🍼✨

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

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!

Works as it should for a replacement part

Perfect replacement

Replaced my original duck bills perfectly

These fit exactly and are a perfect replacement. Other duck bill valves claim to be compatible, but this is the only compatible duckbill valve for the eufy breast pump S1 pro l. don’t choose anything but the eufy branded valves.

great replacements!
