Duckbill Valve Silicone Diaphragm Compatible with Mommed S21 Wearable Breast Pump Replacement Parts

The packaging is great and the pump parts always work as they should.

All of the parts ordered are defective for my mommed S21 pump. My pump worked just fine before but after losing a part I ordered these to try and have went through and tested every piece. The suction doesn’t feel right with these. I have even tested them with a full pump session and came out with less than an ounce for each side when I normally pump 2-3 ounces each side.

Exactly what I needed, extra parts for my wearable mommed.

The sizing of these flanges and parts fit perfectly. They are identical to the original that came with my pump when compared with the originals, the quality, durability and function appear to be exactly the same. These are a great value for the money will increase the usefulness of your pump. I love that they came in a storage box! They are compatible with my mommed s21.

These are a perfect fit for the mommed pump and the quality is just as superb. I will be getting again when I need more replacements.

I ordered two packs of replacent duckbills and diaphragms for my Mommed S21 and all eight of the duck bills came with very visible openings at the tips. There is no option to contact the seller. Would not purchase again.

They are soft and flexible with no sharp edges, very good quality. I like that they are transparent because it makes it easy to see if there is any dirt or debris. Love that they are made of food grade silicone which means they are safe. Love these valves. But they are a little pricey.

Great replacement parts!
