Maymom2nd Generation Detachable Connector with Built-in Backflow Protector and Membrane Not Original Spectra Replacement Pump Parts for S1, S2 Plus, Synergy Gold, SG Portable

I primarily use silicone Pumpin Pal flanges, and unfortunately the design of this connector makes it hard to flip back the silicone flanges as far as they need to go in order to place correctly.Other than that, these worked comparable to Maymom's regular Spectra. I didn't see any differences in suction, and they fit all the other Spectra compatible parts as expected. They also fit regular detachable plastic flanges (Maymom & other brands) well.Cleaning is a bit more difficult because the long narrow tube up to the diaphragm, but I haven't had any issues with milk build up there so far.

I seen these and thought I’d give them a try since I’ve never seen any adapters look like this. Well, they’re not very good. The suction isn’t as good as my others. It’s also a pain to clean. It does come with a teeny little brush that’s way smaller than a bottle nipple brush. If you lose the brush, you’re not going to be able to clean it properly. I wouldn’t recommend these, they have better ones available.
