21mm Flanges 2pc Compatible with Spectra S1 S2 Synergy Gold Motif Luna Breastpumps Replacement to Spectra Pump Parts and Flange 21mm Replace S2 Parts and Accessories

Work great as replacement parts for my Spectra pump. I needed an extra pair of flanges and these got the job done. They are hard plastic, can be put in the dishwasher, and the only real difference I can see from the set that came with the pump is the neck is a bit longer. Additionally, sometimes you have to unscrew and screw it a couple times before it lines up properly with the bottle. These were a great buy and I would purchase them again if I needed too.

Exactly what I needed for my spectra pump. Fit perfectly

Worked great

This is my second child I am breast feeding and pumping for. For my first I could only find size large in stores so I assumed that was normal. Ended up losing my supply at 5 months. I think they were to big because i never really got more than 3 ounces out of a breast. I just used the medium for the first time and got 4 ounces out of each breast. Definitely worth making sure you have the right size.

Love the shape of these flanges. I found them to be true to size and compatible with my Spectra.

I love these flanges! Perfect for my spectra2

Mirror functions great but after a while it gets hard to see like it gets a build up that can not me cleaned.

I love these! I was very hesitant about getting a generic brand because I wasn't sure that they would really be compatible with my Spectra s2 or that the quality would be as good. But I am SO glad I got these! I actually like them BETTER than the originals. With the originals I couldn't get the valve off to really clean inside, and I tried everything, to no avail... buildup still occurred after 3 months' use. At the same time, I was nervous that these valves DID come off because when I bought replacement name brand valves on my first Spectra pump three years ago, they always fell off into the milk while nursing. The Nene ones stay on GREAT and have never fallen off. But, when I need to wash all the parts, they come off easily to fully clean the inside of the flange. I've had Prime for years now and have never reviewed anything, but I was just so happy with this purchase I had to! Highly recommend!

Not come with duct, but can use the ones that come with Spectra S1.

I ordered the flanges however, upon receiving the part of the flange that connects with the tube was too big, therefore there was no suction. The spectra tubing measures 0.6mm whilst the flange connector measures 1cm. Please advise if nene supply provide parts that are compatible with the spectra? Item will need to be returned. Thanks
