Wide Mouth Base Connector 2pc - Compatible with Motif & Spectra S1 S2 Pumps & Bottles; Compatible with Medela, Maymom, Pumpin Pals, Lacteck & Idaho Jones Flanges - Replacement Pump Parts Adapter

Works well to attach soft silicone flanges to spectra pump.

EDIT:Because the last set I had purchased did not fit well, I was sent a replacement set, which fit flanges better than the previous set, though it was not a perfect fit, it made pumping with other flanges easier and more versatile because I can use different flanges for the Spectra instead of the standard ones, which does not work as well for me.___________Purchased this to use with Pumpin Pals Flanges as it was advertised to fit them, however, the connector itself is so tight and small that the flange hardly fits, and causes the flange to fall off from the connector while pumping. Super frustrated as I was excited to get these, and used it right away after sanitizing it.

It works okay for being an off-brand product. However, the lid fits very loosely. When you screw it on, it doesn’t fit tightly and it comes off easily. The vibration of the spectra can easily cause the lid to loosen. Also mine came with a giant hole in the top of each one and the same spot (I’m guessing so air can escape?) and I don’t remember my spectra flanges having these holes. If they do, they aren’t this large and obvious.Update—they sent me replacement parts and were very communicative regarding the issue I was having. Great customer service! The lid is still a bit loose, but I genuinely think it’s just a manufacturing issue. And these ones do not have large holes at the top.

Used for lacteck flanges in my Luna motif. Does work but if it falls forward, it spills from the sides. Good for the price but be careful not to tip bottles over. Also hard to clean, gunk gets stuck you need to bend a bristle brush to get into the cornersEdited comment: I rated this 3 stars but changed it to 5 stars because the excellent costumer service team refunded my purchase completely unsolicited. Obviously my review still stands true but the way the company handled it was very impressive.

If you're trying to personalize your Spectra flanges and need a connector, these are awesome! They work with all kinds of flanges and are easy to clean!

These absolutely suck. I use 5oz bottles with these. Halfway full and it’s like it too heavy and they disconnect and fall. I’ve lost so much milk because of this. Milk spills from where you tighten it to the bottle even tho I make sure it’s super tight. Do not waste your money on these

Ordered these as an alternative to Maymom adapter because these screw securely into Mila's Keeper glass storage/collection wide neck bottles. Haven't tried to pump with them yet but here are comparison photos in case it's helpful for anyone. Idaho Jones on the left or on the top in the photos.

Exactly what I needed for a second set of pump parts for my spectra and PGA.
