Nenesupply 4pc Duckbill Valves Compatible with Wearable Elvie Breast Pump and Pump Parts Replacement Parts. Made by Nenesupply. Not Original Elvie Valves. Use with Pump Seals.

Worked with Elvie OG no problem. If I look closely I can tell the difference. No difference in output from me. I wash in a bottle washer and dishwasher and no issues with warping

Perfect fit for Elvie pump

Perfect replacements!

These duckbill valves are a great dupe for the Elvie. Both photos show the manufacturer duckbill valve on the left, and the Amazon product on the right. There are slight differences, but they work perfectly with my pumps. They give great suction and I get the same output as with the originals. The rubber is slightly stiffer than the Elvie brand duckbills, which I found actually hold up better through repeated use and washing. Hard to beat for the price!

Works even better than the name brand and much cheaper! Definitely recommend.

Perfect replacement. Fits well and improved suction after original parts wore out

I was nervous to order parts that weren’t from Elvie. I needed new parts but didn’t want to spend a lot of money. These were identical and a fraction of the price. They fit perfectly and I have nothing but great things to say. Save your money and buy these.

Works just as good as the original and was delivered quickly! The only difference I saw side by side is there is a tiny little number imprinted on these, but made no impact to the efficacy of the pump. Would buy again!
