Nenesupply 4 pc Duckbill Valves Compatible with Lansinoh Pumps Parts and Breast Pumps Replacement to Lansinoh Valves. Use with Signature Pro Smartpump Manual Pump

Love these for my Lansinoh pump. They are actually a little tighter fitting than the originally duck bills that come with the pump itself. Would definitely recommend!

Work well. Compatible with my lansinoh smart pump 3.0

I exclusively pump for my babies and have been for over three years now. I always am replacing my duckbills to keep my pumps pumping correctly. These have been perfect and easy. Especially as a stay at home mom where getting out of the house is another chore, being able to order these online and have them arrive ready to use is a life saver.

Works perfectly with the lansinoh manual pump!

Purchased these to use with a Lansinoh manual pump and they fit perfectly. They are durable and hold up through many hand washes. Great value.

A little tight on my “Lansinoh” pump and are hard to take off. But they get the job done.

I was worried buying not the lasinoh brand replacement parts, but as a single mom on a tight budget, i learned to deal. These worked better than the lasinoh ones actually. Tighter, longer lasting seal making the suction a step better. Also last longer, they were made much better.

I order these because my valves from my Lansinoh pump kept tearing. So far I have used these for a couple months and they have no torn. They fit perfectly on my pump and I am so happy with this purchase.
