Flange Insert 17mm 6pcs, Flange Sizing Kit Compatible with Spectra Flange, Spectra Pump Parts, Momcozy Wearable Breast Pump, Manual Breast Pump, Spectra Breast Pump, Medela Pump Parts and More

Flange inserts are as described and fit my Spectra pump flange well. They are very secure and have adequate length to accommodate any stretching. Help ensure comfortable use of the standard pump flanges.

I bought these instead of buying new phalanges for all my different pumps and it saved me so much money. I consistently use three different pumps and these work for each one!

Size 16 n*pples so I thought 19 flanges would be a good size and I was right! These are so comfortable in my medela hand pump. Great quality!

Good replacement parts for my portable pump, purchased every other month.

Really great for pumping more! I realized I was a size 21, and my flanges are 24s, so this was great. I definitely pumped more milk with these inserts!

These are a sturdier plastic and not as soft as the Momcozy or willow brand flanges, but they do work.

Does what it’s supposed to. Not the most comfortable though.

Fit well into a standard 24mm flange. Easy to install, remove, and clean.
