Sorry mamas in the US, 17mm is out of stock there! Order now and we will ship your order around 12 Dec. 

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.

Great product, Great customer service

The product is great, especially for "elastic nipples". The silicone is soft and flexible while the holder is a firm plastic. The holder is all one piece so you don't have to worry about the flange detaching while trying to remove them w/one hand from the "hands free" bra. I also like that you can use them with pretty much ANY pump of your choice, I use mine with my Medela pump since I like the suction of that one but hate the flanges. Price point is great AND if you find yourself with the wrong size OR it doesn't work for you, the customer service is awesome. Take it from someone who has tried virtually every flange out there, this is worth the try, it's my everyday one.

Comfort matters!

Using the liquid shield versus the plastic flange is like night and day. Pain-free and more milk!

Comfortable pumping

These have allowed me to have much more comfortable pumping. I won’t go back to standard flanges.

Review of liquid shield

Been using these coz of the rave review together with my cimilre/S1 pump as the flange from the cimilre is too hard and too tight. Initially took some getting used to. On the Spectra S1 that I was using previously I also had to lower all the settings to get a comfortable pumping experience. Realized that I didn't have to if I were using the cimilre pump. Would love to try the liquid shield with pumpables pump next time. Think I can get more milk with the liquid shield but maybe next time can make the plastic flange part smaller as it is barely able to fit through the holes of my handsfree pumping bra.
