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.

Works great, easy to clean. Nice to have multiples that will work in varying brand of pumps. Works best if you apply pumping spray before insertion, otherwise it can be difficult.

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.

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

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.

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!
