Widemouth Connector 2pc Compatible w Spectra S1 Spectra S2 Pump; Compatible with Medela PersonalFit Shield, Pumpin Pal Shield, Lansinoh Flange, Maymom MyFit Shields, MyFit Crater Shield

They work just like I need them to. The pano flanges I got needed an attachment like this to connect to my spectra bottles. It’s wide mouth and also fits the spectra backflow valves

Wish spectra would make these standard when you get their pump. Handy to have these while you figure out which flange size is the right one. Rarely are people the size that’s given in the pre-formed flange/elbow piece given

Maymom adapter initially APPEARS to fit Mila's Keeper wide neck glass storage bottles but it's DECEIVING - the issue is that it untwists with ZERO resistance, as though it never screwed all the way down even though it is screwed alllll the way down (even tried removing the silicone bottle sleeve). However, good news, Idaho Jones, Nenesupply, and Pumpmom adapters/connectors all screwed into Mila's Keeper securely (esp Pumpmom was really snug) and would allow you to use a flange of your choice and still pump directly into the storage bottle.

Does the job

Bought these to use with LacTeck flanges, and they work perfectly to connect them to my Spectra bottles!

Super Duper. It fits lansinoh attachments making it work on Spectra S1 Plus.

These will fit as adapters for Spectra with LacTech flanges, but the fit is not secure. The flanges are a tight fit and can pop out very easily and you’ll lose the milk collection bottle if you’re not careful.

Perfect for my spectra! I wish more pumps had better size changes. Since spectra doesn’t make the smaller sizes, I bought this so I could buy a properly sized breast shield. This fits the spectra perfectly and I get a decent pump sessions with it. Very easy to clean and sterilize though. I ended up ordering a second set to help support washing/sterilizing downtime. Highly recommend!!
