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

As described. Works well with the pump. A little more snug and feels more durable than the manufacturers valve that came with the pump which is kind of nice. Would buy again if replacements needed.

As a cautious mother and woman, we must always have a spare for our extractors, because they can be lost or broken, these are a great option which suits perfectly with my extractor.

Compatibility is exactly as stated. These work perfectly with my Smartpump 3.0. I actually prefer these to the lansinoh replacement valves, they don't seem to gap as easily.

I was nervous at first that they wouldn’t fit, but these fit my lansinoh manual pump perfectly! They are snug and don’t fall off, provide good suction, and clean easily. They look exactly like the original that came with the pump!

I usually regret it when I buy knock off parts, but not this time! After reading the reviews I decided to try these. They are just as good if not better than the Lansinoh valves! They have a nice tight fit and 2 little pieces that stick out on the side for easy removal. That way you can also distinguish them from other valves (I have so many lol). I have bought a ton of replacement parts over the last year and a half of pumping. I feel good I can at least save a little money on these!

These are actually great duckbills. Worth the money. Goes well with lansinoh hand pump

These valves and really good. Works perfectly with our signaturepro double electric pump. If you compare both valves these are smaller than the original valves but made with and strong material. But don't worry, it's fit perfectly and works like the original. Definitely will buy again.

these worked great for me instead of buying the super expensive replacement ones. great suction and lasted just as long!

Son perfectas para mi extractor lansinoh… la verdad es que dudaba en comprarlos porque no eran los de la marca pero leí comentarios positivos y la verdad es que funcionan muy bien, encajan perfecto 👌🏼 y me llegaron antes de la fecha estimada. Realmente los recomiendo mucho, no se arrepentirán de comprarlos Me siento feliz por mi compra

Update for July 13, 2024: Same as the other reviewer from June 27, 2024, I previously ordered these and they were perfect for the Lansinoh SignaturePro pump. I re-ordered the same item, but the set I just received were way too big. The correct size is diameter 21 mm, and I received ones with diameter 28 mm. I will return them. Original review: The Lansinoh pump is excellent, but after a while the included white duckbill valves did not seal well, so there was a loss of suction and the pump was less effective. These Nenesupply duckbill valves provide a tight seal, and work perfectly. Tighter seal than when the Lansinoh parts were new. Recommended.

افضل من الي جات مع الشفاط مره ممتاز

Me encantaron, son incluso mejores que ls originales que traía mi extractor, son mas gruesas y duraderas. Lo volvería a comprar sin duda!

Good suction-feed my Lanisoh pump
