The Liquid Shield system by Pumpables is different from traditional hard flange systems because it contains a soft interior insert, the Liquid insert.  This is made out of lovely soft liquid silicone, and it works very differently from a traditional flange. 

The Liquid insert moulds to the breast tissue, and provides a soft environment for the nipple to be drawn down. Because the Liquid insert is full-length, and extends all the way from the breast right past the nipple, there are no edges or friction, just a nice comfortable material of liquid silicone. 

As the Liquid insert is flexible, when your breast pump applies suction the Liquid insert will actually collapse down around your nipple, which helps compress and massage the nipple. This mimics the way your baby's palate compresses the nipple when she is breastfeeding.

Which shield size to choose?

To figure out your size, measure your nipple using our measuring tool.

The best shield size will fit snugly around your nipple, with no areola.

We know it can be confusing figuring out shield sizing, so we really recommend you get in touch if you need fitting help.

Tip most pumpers are using too large a shield, so have us help if you're not sure 💁.

This listing is for one single pack of the full Liquid Kit. This means it includes:

Liquid insert in your chosen size

Breastshield assembly

Breastshield cover

Seal diaphragm

Seal cap



Bottle lid

Bottle stand

Neck adaptor (wide to narrow)

If you're wanting to double pump, please make sure you add 2 kits to your cart. It's fine to add different sizes.



This shield fits with wide neck bottles. If you're using narrow neck bottles, you can still use Liquid Kit with a wide to narrow bottle neck adaptor (or just buy some cheap wide neck bottles). 

Breast pumps

The Liquid Kit is a closed system, so you can use it with any pump (i.e. Spectra). You must use the entire Liquid Kit when pumping (you cannot use just the Liquid insert with breastshields from another range). 

The Liquid Kit comes with a standard sized silicone tubing, but some pumps i.e. Medela need a connector attached to the end of the tubing in order to connect it to the pump. If you're using a pump that has a tubing connector between tubing and pump, you may not be able to use Liquid Kit.

I’m a bit of a pump collector and I have to say the super genie with liquid shield kits is the best thing since sliced bread!!! It has made pumping at work so comfortable, I look forward to my next pump session! The liquid inserts are little silicone clouds for your nips!! If you are on the fence, DO IT!

Don’t recommend if you pump above the absolute lowest setting

A huge waste of $60+ for me. It doesn’t work if above the lowest setting on the spectra or else the pump membranes don’t work properly. Apparently according to the FB group, this is a common problem For people. Caused pump trauma + inadequate emptying resulting in mastitis. There’s no one to call. The fb messaging option isn’t helpful and you can’t return. Just out $60 for flanges that I am now terrified to use after the mastitis it caused (3 EBF KIDS >1 year each… never had issues before using this flange kit)

Only thing to really work!

I’ve tried multiple pumps and flanges and ultimately found out about pumpables through social media. I was skeptical because it was cheaper than other products and the liquid shield kid was completely different from anything I had ever tried. My supply was dropping and my nipples had gotten so sore with other pumps and flanges, I was afraid I would have to give up exclusively breastfeeding… until I started using pumpables! The liquid shield system really works for me and elastic nipples. I choose the size I measured as and one size down. I did not size up like is recommended with other flanges. I find the exact size or smaller helps best with my nipples. I also can still use my spectra pump with the liquid shield system which is a HUGE plus for me. The pump it self is great. Super quiet! It’s very similar to spectra which I love. The battery life so far is excellent. I’m recommending this product to all my nursing momma friends. The ONLY thing I wish is for pumpables to make a liquid shield cup system so I could use this system discretely at work. I’m hopeful they will develop one! So far I have had no luck with other cups. I’ve hacked this pump with different cups and unfortunately I really think it’s the liquid system that helps remove my milk. Thanks pumpables!

Great, almost perfect

Love this pump kit. The silicone is much more comfortable than my usual plastic breast shields and I think it even helps get extra output. The only downside (pretty minor) is that the set up is a little more complicated / more pieces to keep track of. Sometimes it's tricky to get the silicone insert properly set on the plastic shield. It's a small inconvenience overall. I'm happy with the product in general.

I can never go back to hard plastic flanges after using Liquid Shields! Such a more comfortable pumping experience, not sure how I survived the first few months without them.

Great output, and easy to clean

I love that this kit only has 4 parts to clean per set! I use it with my Spectra pump, and I greatly appreciate that it takes far less time to clean compared to the original Spectra parts. Plus, I don't have to worry about additional inserts as the 15mm size Liquid Shield Kit works great for me. Do not put the liquid seal cap in water! Plus, output is great. I got 4 oz on one side with the Liquid Shield Kit and under 2 oz with the Spectra parts on the other side in the same session. I started with one set to try it out, and I'll be ordering another!

So far I’ve loved this pump. It has equal hospital grade suction and is very comfortable. Parts needs replacing frequently as with any pump. My only complaint is the liquid shields sometimes slip off the edges, but otherwise it’s been great!
