PumpMom Backflow Adapter for Spectra S1, Spectra S2 Pump to Use Most Medela Flanges and Bottles; Connects Between Medela Breastshield and Spectra Backflow Protector (Pumpmom Flange Adapter)

It was great I have spectra hand me down with Medela left over from hospital supplies this fit perfectly worked with Medela attachments that’s I own and have gotten used to

Great adapter that allows for ease of use with any parts. I have four parts that I rotate with use on my spectra thanks to this adapter! Currently using medela and maymom brand parts with my spectra since spectra parts are hard to find!

I really loved my medela pump parts and wanted to use the same with spectra s2. Spectra parts are too large to use and takes too much space in my washer. These adapters work perfectly.

These worked perfectly to adapt my Medela flanges for my SpeCtra pump. The 24mm SpeCtra flanges did not fit me well. A decade ago I used a Medela pump with my first 2 kids and I still had the 24mm flanges. The hospital provided a Medela pump kit which came with new flanges. I mention this because the newer flanges are slightly different. This adapter worked well and fit both types, but it comes disconnected more easily from the newer flanges. I was going to buy the 20mm flanges from SpeCtra, but they were expensive! This was a much more cost effective option! I almost returned these because I thought they didn’t fit at first... but my pregnancy brain just forgot how to assemble my pump parts 🤦🏼‍♀️. So, double check before you assume it doesn’t work.

I used the adapters with the spectra s1 tubing and the medela personal fit flex connectors. The small end fit the medela end just fine but the larger end wasn’t snug enough to provide a seal with the spectra tubing. I improvised originally by trying gorilla tape to form a seal. It kinda worked but I found a better solution using a plumbers tape instead. It was a bit annoying that I had to rig it up but now that I found the right tape I’m very happy with the adapters because the spectra flanges we’re just an epic pain to place into a pumping bra.
