eufy Original Diaphragm (2-Pack) for Wearable Breast Pump E10/E20/S1/S1 Pro, Food-Grade Silicone, Suction Regulation, Easy to Clean and Install

These caps are a must if you own the any of the eufy pumps. I have tried bending over completely and laying almost all the way down and they have not leaked when using these caps. It would be great if they were already included with the pumps, but they are definitely a must. The price is a little high but they come with four and will last probably as long as you don’t lose them.

These work perfectly for my eufy pumps! Easy to clean and durable. No issues with these as I replace my pump parts every 30-60 days.

Good condition

Good

I got these on April 30th, it is May 13th and I already had to get out the second pair as I noticed a gap in the valves while at rest. I use this pump maybe 1-2 times a day at most. There are definitely days I don’t use my Efuy at all. And according to their website I should have to replace the duck valves every 2-3 months if I’m using it that much.Well when I got out the second set there was already gapping before I even used it! I’m very disappointed that I spent more to get the Eufy brand duck valves and the quality is just not there.

I was breast feeding for over a year and was very thankful to find out thta amazon had parts to my pump. I would have had to throw it away but due to me get the new pasrt i used it for my second child.

Fit my eufy s1 pros perfectly

These are really hard to get your hands on but way better than generic brand. Definitely hold out to get these ones!
