Nenesupply Compatible 21mm Flange for Spectra S2 Spectra S1 Breastpump. Made By Nenesupply. Not Original Spectra Pump Parts Not Original Spectra S2 Accessories Not Original Spectra Flange

These work with my spectra pump. They are interchangeable with spectra parts and work just as well in my opinion.

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!

I was in need of a second set of flanges as I am exclusively pumping and didn’t want to constantly clean pump parts. I found these after a quick search and they’re perfect! I haven’t had any issues. They fit perfectly on my Spectra pump. The valves can be a little difficult to remove but a little twist at the base does the trick. Will purchase again when I’m in need of replacement parts!

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

Every breast pump accessory I have bought never comes with the correct size flange for me. I was so thrilled that I was able to purchase these for a great price, and they are fully compatible with my pump. They are comfortable, durable, and so much more convenient than going through medical supply companies.
