Size Guide

Our Advanced Flow All-In-One Kits are an easy to clean 'all in one' design and do not have a traditional valve and membrane. These kits are available in 3 sizes - 21mm, 25mm and 29mm and are sold individually. 

Sizing is important when it comes to comfort and effectiveness during pumping. While we try to provide the most 'common' sizes with the breast pumps, sometimes a different size is required.

For a quick ruler guide Download our Suction Kit Sizing Guide here. This can be printed and used to assist you find your best fit.

Signs you might need a larger size:

  • You are unable to centre your nipple i.e have it inside the tunnel without it touching the sides
  • You feel your nipple is uncomfortable and rubbing against the side of the nipple tunnel during pumping
  • Your nipple is unable to move freely with the pumping motion
  • Your nipple is being strongly compressed by the 3 phase motion to a feeling of discomfort or pinching

Signs you might need a smaller size:

  • An excessive amount of your areola is being drawn into the nipple tunnel
  • You experience a painful tugging feeling
  • Your nipple is reaching the end of the nipple tunnel while pumping
  • You can hear air moving or 'sucking' inside the nipple tunnel
  • You are not experiencing compression of the nipple with the 3 phase motion
Sizing Guidelines
We recommend having 2-4mm of space surrounding your entire nipple for optimal fit. You can find your size by measuring the diameter of the base of your nipple, then adding 4-6mm to find the nearest size, if between sizes, it is recommended to go for the larger size.


15mm diameter base of nipple, add 4-6mm, nearest = 21mm

20mm diameter base of nipple, add 4-6mm, nearest = 25mm

23mm diameter base of nipple, add 4-6mm, nearest = 29mm

    Worst pump I've used

    Might be good for others but it didn't work for me. Can barely get any milk. I've invested in all size flanges, nothing works. It's the worst pump I've ever used

    Hi Emi, I'm so sorry that you have found that the breast pump has not worked for you. I know you have been working closely with Hannah to try to achieve the results you desire. We have a new product recently, the Air Flow Suction Kit and I think this might help your journey. If you would like to talk more about this please contact us again at x Kind Regards, Laura - Director, Milkbar.
