S12 Wearable Breast Pump Accessories Universal Duckbill Valves, Original Part Accessories Replacement, Electric Breast Pump Parts for S12/S9/S10, BPA Free, Food Grade Silicone, Easy to Clean, 6 PCS

Dug up my pump after not using for the past year for my 2nd child, and was distressed to find there was no suction. Used these to replace my duck bills and it now works like new. I use these with my spectra caracups and they fit perfectly and suction is great!

Has all the types for wearable pumps. It would help if there were two each.

I have the spectra caracups and this is a great replacement dupe for the spectra duckbills. Spectra duckbills are 14.99 for one pair and these are 9.99 for 3 pair. It does the job but honestly if you are an exclusive pumper they will not last long as I replace them every two weeks or so as I feel it’s losing suction.Update: I am not sure what’s happening but last few times trying to order the 6 pack of duckbills I keep receiving a pair of duckbills and a diaphragm. I am unsure if the company mislabeled their products or amazon workers are clueless. This has caused me to stop purchasing entirely bc I do not want the risk of getting the wrong item.

If you are looking for a valve to fit the original momcozy s12 this is it!!I kept getting sent the valve for the s12 pro(from but the manufacturer and on Amazon) and it did not fit. Way too short.But this one definitely fits the original s12(not the pros!!!). It’s the longer valve. People says it touches but it does not touch the container. It’s the same as the original. It fits like the valve that originally came with the s12. I’m one happy customer finally!!

They are a bit long for the momcozy s12. They do work but only for about a month & then they won’t stay on. The ones my momcozy s12 came with worked for 3 months before needing to be replaced. I will use them till they don’t work as I don’t want to waste them but I won’t order again.
