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.

Game changer

I hated the feel of traditional flanges, I tried several other flanges and none were right for me. So glad I found pumpables even if it was late in my journey!

Liquid Insert

Great product! Makes pumping so much more comfortable. Only hope that each liquid insert could have last longer to maintain effective pumps.

Only Comfortable Option

I have tried several different pumps and flanges including standard plastic flanges from Spectra in different sizes and Pumpin’ Pals searching for better comfort while pumping. These liquid inserts where the only ones that didn’t leave me sore and dreading the next pumping session. I love the silicone feel and the way they contract to massage the nipple while pumping. The only thing I wish differently is that they came in more sizes as the 17mm is too small and 21mm is a little too big for me. However, using a slightly larger flange size in the liquid insert is still more comfortable than the perfect fit of standard flanges.
