5Pack Silicone Duckbill Valve & 4Pack Silicone Diaphragm Compatible with momcozy S9 / S12 / S9Pro / S12Pro Wearable Breastpump, Breast Pump Replacement Parts, Breastfeeding Essential Accessories

I originally ordered these to use on my momcozy S12 but I ended up using them with my hand pump (evenflo brand) and my wall pump. They are pretty universal and they actually worked better and stayed out better on my momcozy! The duckbill that originally came with my momcozy kept sliding off while I was pumping no matter what I did (I only used it 3 or 4 times before this) I popped one of these on and it works a lot better and stays put. Also easier to cle.

I took a chance and bought these for my Baby Buddha and got lucky. These fit and are much cheaper than the replacement parts from Baby Buddha!

First and foremost, I must commend you on the exceptional quality and functionality of both the silicone duckbill valves and diaphragms. They are impeccably crafted, and the silicone material feels sturdy and safe for use with my breast pump. I have found them to be highly effective in preventing milk backflow and ensuring a seamless and comfortable pumping experience.Additionally, I greatly appreciate the convenience of having a pack of silicone duckbill valves and diaphragms at my disposal. It provides me with peace of mind knowing that I have spare parts readily available, especially during busy days when time is limited. The inclusion of four silicone diaphragms is particularly valuable, as it ensures that I always have backups on hand when needed.Furthermore, I would like to commend your company for its exceptional customer service. From the moment I placed my order to the timely delivery of the products, the entire experience was smooth and hassle-free. Your team's dedication to customer satisfaction is truly commendable, and it has left a lasting impression on me.In conclusion, I couldn't be more satisfied with your 5 Pack Silicone Duckbill Valve and 4 Pack Silicone Diaphragm. They have exceeded my expectations in terms of quality, functionality, and convenience, and I would not hesitate to recommend them to other breastfeeding mothers or anyone in need of reliable breast pump accessories.

I use these with Momcozy S12 Pro. They're a good fit.

It does its job but not as soft as the originals so takes another few seconds to put together the pump parts.

These are compatable with the Medela hand pump. I struggled because I feel like my milk never really came in and with the addition of the duckbill flange helped me get every drop out. I was able to provide my baby atleast with some breastmilk for the first month and a half of her life thanks to these.

Worked perfectly!

These work great. I used them with the Legendairy Milk Cups.
