8pc Duckbill Valves 4pc Pump Seals Diaphragm Compatible with Wearable Elvie Breast Pump and Pump Parts Replacement Membrane Parts

The spouts are fine but the other piece is a bad fit and unusable with elvie.

Didn’t know how badly I needed to replace my pump parts until I installed these! Man do they ever work great. No issues with compatibility. Nice little clear case it comes in.

Absolutely loved these to use as extras with my Elvie! I had previously ordered a different brand which were pink and they did not work at all. I believe they were too thin or loose so the pumps would not suction. These exceeded my expectations and didn’t give me any trouble! They shipped and were delivered very fast and are a good quality - thick yet pliable and worked perfectly.

Work great and fit like they are supposed to.

Got these knowing it could work or be a flop. I replaced the original duckbills and membranes and my supply increased! Not only that but I feel these fit BETTER than the originals for the membranes. The little side hooks seem stronger and more stable. I will be sticking with this brand for my replacement pieces for my Elvie pumps!

There's a good number of pieces here for the price and honestly when it comes to pump parts you can't have enough, in my opinion. The material is a little thinner that Elvie's so you need to be a little gentler but otherwise this is a pretty good dupe, stock up!
