2X 17 mm Maymom Wide Neck Pump Parts Compatible with Spectra S1/S2 Pumps; Incl Wide Mouth Flanges; Not Original Spectra Flange; Replaces Spectra Shield (Two Small Flanges)

These flanges were a good price and worked great on my spectra s 1 plus. Would recommend for anyone who needs to order additional sizes or spare parts.

I’m really happy to have a properly sized flange & good quality duckbill valves. While the lid screws onto & “fits” the Spectra bottles, it is NOT as good a fit as the Spectra flange lids. It seems like the tops may have too much tread, so if you bend over & your bottle happens to tip, it will leak around the tread. If you advertise something as fitting, that should not happen. I cannot tell you how upset I was when I noticed the amount of milk that spilled around the tread of a closed bottle. No bueno. I think I will just get flange inserts and use the Spectra flanges to prevent any spilling. Annoying.

Works great for what its intended for.

Great suction. Im glad I was able to find flanges that are smaller then the standard size 24 that come with breast pump. Ive only used the flanges for 2 days and have noticed a significant difference in the fit and the amount of milk Ive pumped.

Loved them for about a month, then they cracked. I only pump once a day too so not over use and I take great care of them. :(

Good

I guess I am not the average but I was so happy to find a replacement for my spectra pump parts that actually fit what I needed! They are a little hard to clean the inside but not impossible. i actually bought these twice as I pumped for a while and needed to replace! Would buy again if needed.

I was so excited to actually use a flange size that was right for me but when this arrived there was a hole in the package and the pink duckbill pieces were missing…. Flange works great but sucks to pay for something and not get all parts!

This sizing fit much better for me than the standard sizings. It also works perfect with my spectra pump. Wouldn’t even know the difference between the spectra flanges and these if it wasn’t for the brand names on the flanges.

I was hoping to increase my supply with a smaller flange but it did not help. However the flange works just like the Spectra one. No issues with the flange.
