Liquid Insert [Pack of 2]

Size Guide

Pack of 2 Liquid inserts for use with your Liquid Kit.



Liquid inserts last about the same amount of time as duck valves, so you should expect to replace them every 2 months of light use up to every 2 weeks if you're an exclusive expressing mama sterilising after every use.

You'll know your Liquid insert needs replacing when you see any visible fraying or stretching along with the valve or if suction drops when pumping. Please be aware that valves are so crucial when pumping for maintaining suction! They do need replacing regularly, so keep this in mind.


Please be aware that you cannot use Liquid inserts with traditional hard flanges. The Liquid shield assembly is specially designed to fit the Liquid insert - the insert won't be able to fit into a standard flange.


If you're not sure which size you need, please get in touch so we can help. You can use our sizing guide at pumpables.co/measure to get started.


All Pumpables parts in contact with your milk are free from BPA, phthalates and other nasties.

    It make expressing more comfy but it would be best if the liquid shield is more long lasting so that mum who express frequently need not change it bimonthly

    Best Pump!

    I have a great time using this product, its not painful compared with other brand. It encourages me to pump 8x or more a day.

    The change I needed

    I initially ordered 25” as that’s the size I’d used previously un medela (size M), but then I discovered I had elastic nipples and that the bigger size I should use is 21”. And indeed it made all the difference! Paired with the Legendairy Milk Nip Dip and Pump Spray, not only is my current pumping experience 100% pain free, but my yield went up 20-25% from the first use. I’m a diehard Pumpables fan!!
