Custom Flange Fitting



Did you know most people use the wrong size pump flanges?

Are you pumping on a schedule? Exclusively pumping? Pumping at work? Have a NICU baby?

YOU NEED A FLANGE FITTING!

Flange fitting rulers are available all over the internet but they’re inaccurate and nipple diameter is only one aspect of flange fitting. Imagine trying on shoes. I can measure my foot at a size 9 but that doesn’t mean that every size 9 shoe will be right for my foot. I need to try on a shoe and walk around to know how it feels in motion. There’s so much more to flange fitting than a simple measurement!

Flanges smaller than 19mm were not created until the end of 2022. Size 11mm flanges were made available in January 2024 and new shapes continue to be churned out (I added new shapes Fall 2025)!

If you are planning to pump consistently, you need a flange fitting. Pumping should be comfortable, not annoying or painful. And you shouldn’t look like you have traffic cones for nipples when you’re done!

Properly fitting flanges…

  • Improve pumping comfort (pumping should NOT be painful)

  • Significantly decrease the chance of nipple/areola damage and mastitis

  • Improves pumping efficiency (ie saves you time and energy)

  • And perhaps most importantly, maintains milk supply

But I was sized in the hospital!

Did they have you try on hard flanges (not inserts) in the size they recommend? Often hospitals size people incorrectly because hospital rules don’t allow them to have the proper equipment.

Measuring nipple diameter is just a starting point. There are currently 5 different flange shapes (not all sizes have 5 shapes) available and a ruler can’t tell you which shape fits your breast the best or how easily milk will flow.

Trying on several sizes and shapes is much more accurate and can change your whole pumping experience.
