Liquid Insert [Pack of 2]

68 reviews
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 to get started.


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