Milkbar All-In-One Suction Kit


Our 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 4 sizes - 17, 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

What's Included

Full Kits
These kits are compatible with our Advanced Flow Electric, Pure Freedom & Premium Care breast pumps.

Please note these kits are sold singularly - if you have a double pump you will need to purchase 2x kits to make a set. 


    Our inserts are a new, cost effective option should you be unsure of what size you require or if you wish to replace your silicone piece frequently.

    The inserts come in sizes 17, 21, 25 and 29mm. They include only the silicone cushion, and they all fit into the all-in-one suction kits only.

    Great buy, upgrade to the original suction kit

    Had a second hand pump given to me with old style collection, I upgraded to this one and it's much easier to clean and am happy with the suction as it's more gentle for me. Highly recommend.

    Good to have backup

    Great to have a spare all in one suction kit just in case anything should happen.

    Great tip! Thanks for the review :)

    A good Fit

    I find the 29mm suction flow a good fir for me and prefer it to the pinching of the other kit.
