NENESUPPLY19mm 2 pc Flanges Duckbill Valves Compatible with Spectra S2 S1 9 Plus Synergy Gold Breastpump Replacement to Spectra Pump Parts Flange Accessories Wide Mouth Work with Backflow Protector

These flanges made pumping easier. Before this purchase, pumping was a pain! Now, I’m able to make it through a full session with minimal issues!

I was unaware I needed a different size flange. These worked seamlessly with my spectra pump. It’s also nice to have an extra set on hand. Good price

I found out about flexible silicone flanges after I had already purchased these. I’m thinking those would be more comfortable.I also find these to be hard to wash. I’m not always confident I’m reaching the inside well enough.However, it works well with my spectra pump, and I was glad this size was available. It’s been hard to find.

Good quality, fit my Spectra pump parts exactly.

If your flange size is wrong it could negatively effect your milk output! Bought this after measuring and immediately noticed a difference!!

I really like my spectra

They fit the spectra bottles, but you have to ensure they're screwed on perfectly. I ended up having to buy this brands bottles to make sure I didn't have anymore spilling accidents because I thought the flange was properly screwed on (which you don't know until you actually tip the bottle because it feels properly snug).

Good flanges. Works with spectra 2

Didn't realize my nipples were smaller than the average woman until trying different brands and shopping for breast pumps. After all my research I knew the Spectra S2 pump was for me, but I also knew the standard 24mm and even larger 28mm flanges that come with the pump would not work for me. Wanting to maximize my pumping experience I was happy to find these smaller size flanges that fit the S2 model. They are completely compatible and work great!

Love these. Feels the same as my spectra flanges. The base is a bit smaller though so if you need the conversion parts so that you can use narrow bottles, the base and conversion don't line up exactly. DOESN'T AFFECT THE PRODUCTS WORKING TOGETHER THOUGH :)

Just what I needed! Thank you so much, I don't understand why the original manufacturer does not make this size, but I am sure happy you did. No more pain and more milk.

It does the job. Needed a smaller size that didn’t come with my pump. Fits my spectra s1 parts! Great quality so far

Fit my pump perfectly and was the size I needed.
