Features

  • Bliblo diaphragm & duckbill valve are suitable for electric hands-free breast pumps, including S9, S12, S9 Pro, and S12 Pro models. We have improved our product, and now the duckbill valve is shorter than the previous version, ensuring it does not touch the cup wall for a more comfortable and efficient use.
  • Safe and Hygienic Materials: Crafted from BPA-free and food-grade silicone, these pump parts are not only safe and soft to the touch but also completely odorless. They provide the utmost safety for both you and your baby, letting you pump with peace of mind.
  • Pump Efficiency: The diaphragms help maintain a secure seal to prevent milk leakage during pumping, while the duckbill valves efficiently channel your milk into the container, minimizing waste and ensuring every drop is saved.
  • Convenient Cleaning: Designed with busy moms in mind, all parts can be quickly and easily washed with warm soapy water and thoroughly rinsed. For deep sterilization, they can withstand steam, boiling water, or microwave steam bags, offering multiple ways to ensure hygienic milk collection.
  • Professional After-sale Service:Your satisfaction is our encouragement to pursue high-quality service and products, have any problems, please contact us, we will assist you within 24 hours!

  • Spectra Dupe
Works perfect on my spectra pump. The pink gives me a little extra motivation to make pumping fun.

  • Works well
Size: 4 Piece Set
After the original duckbill valve tore, I found these replacements were half the price of the original parts so I decided to try them. You can tell the material is thicker and a little different than the original manufacturer's parts, but it does work as intended. They have outlasted the original part so far (by about a month) and have not started to show any wear. I would buy them again. ... show more

  • Does not stay on!!
Size: 4 Piece Set
The one from Amazon is significantly smaller and thinner in size… the duckbill slips off once you turn the pump on. When I actually got it to stay on it popped off after I pumped causing all my breastmilk to spill out of the flange part. It’s a headache especially because this pump is supposed to be for convenience. This has popped off while I’m driving or in places I can’t easily take the pumps out my bra open it up and try to put the duckbill back on just for it to keep slipping off. The Amazon duckbill is on the left the original duckbill that came with my momcozy s12 pro is on the right ... show more

  • The best duckbills
Size: 4 Piece Set- Duckbill Valve
I have now exclusively pumped for two children and these are above and beyond the best duckbills that I have used. I will only buy these when I need to replace mine because they give me the best suction and have increased my milk production as a result

  • Not exactly like the MomCozy ones
Size: 4 Piece Set
These will fit but a little large. I plan to buy the name brand ones next time since they aren’t as similar as I hoped.
