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!

  • Good quality
Size: 4 Piece Set
Works great for my Momcozy s9pro

  • 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

  • Spectra Dupe
Size: 4 Piece Set-pink
Works perfect on my spectra pump. The pink gives me a little extra motivation to make pumping fun.

  • Was nervous at first
Size: 19MM-Flange Insert
I was so nervous to order these. From the photo I had no idea how it would fit on my momcozy. I ordered them anyways because the momcozy size I had was way too big and hardly got any milk. Getting the right size flange is a HUGE deal in pumping and helping you produce more milk. (Be sure to get measured at the hospital after baby and they'll help you get the right size!) But this product came in and is great quality. It was easy to assemble to my momcozy and was seamless (you can hardly notice I added them to the inside). They were the correct size for what I needed and helped create a stronger suction! The only downfall is it's one more thing to take off and remove but soooo worth it for having the right size flange. ... show more

  • No funciona para moncozy
Size: 4 Piece Set
No funciona. No es del mismo tamaño que el original, es mas pequeño, la valvula se desprende durante la extracción y hace que todo lo recogido se contamine. No pierdan su tiempo, mejor compren el repuesto original
Reviewed in the United States on January 15, 2025 by I didn't like it at all. The colors are darker than the photo. It's not beige, the real color is brown. What's most annoying is that the suction doesn't work, the bowls don't stick to anything, it's not safe to leave the plate on the baby.

  • Easy to use
Size: 21MM-Flange Insert
Easy to use. Easy to clean. Can sometimes be challenging to get into pumps correctly.

  • Worked with Momcozy pumps
Size: 19MM-Flange Insert
I’m a breastfeeding/pumping momma who purchased a Momcozy pump and has a bit of elastic nipples. The size 24 flange I think runs a little big and it has a short “tunnel” so my nipple was getting pulled back far and getting pinched in the top while causing pain and loosing suction. I tried a Maymom insert and cut it to fit bit no luck. I tried the beaugen which worked a but was annoying. Sticky, never really adjusted to the correct size (always loose) and turned an ugly yellow color. I tried these and was worried they wouldn’t work because it covers the suction hole. But they worked! It covers the suction while but there is still room between the suction and the insert so it doesn’t effect output. I was so happy they worked I cried! This is the only insert that worked for me and my Momcozy pump. Saved my pumping journey especially now that I EP. In another review I saw that their insert stuck out a bit but mine goes all the way in. The first two weeks it’s snug and you have to gently push it in or even fold it a bit and flatten it out in the Momcozy pump. Over time it “molds” and slides in perfectly. ... show more
