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

These fit on the Spectra bottles. Good replacement parts

Purchased this for my pumpin pals attachments. They worked perfect. If you need inserts, get this.

This product has a hole for no reason which doesn’t allow it to suction right, I would have returned it but the box was ripped while opening it and lost other parts to it.

Fits my spectra tubing and backflow protector well so I can use non-spectra flange/shield with my spectra pump and parts.They are easy to assemble and clean, wash great in the dishwasher, and perfectly match the original Spectra parts.

I purchased 4 sets of these, and every one the plastic has melted during the initial sanitize. The box recommends 3-5 mins in boiling water. The 1st set of 4 I did for 3 mins. They melted. The 2nd set I did for 2 mins they also melted. I am still going to try to use these for necessities purpose. We are having our baby tomorrow, but I will definitely not buy more. If they aren't able to be used I will request a refund.

Perfect fit for the Spectra bottles and wide silicone flanges. Snug fit at the top and duck bills fit perfectly inside. Very happy with these for the price.

Great fit worked perfectly for the wide bottles I had

Need an adapter for compatibility with pumping pals, and not included.
