Sometimes you just need a spare!

Because we take every opportunity to innovate — materials, manufacturing processes, and design — we've recently made changes to the Cup, Cap, and Connector and are offering them as a complete set.

*If you purchased your Chiller after September 2023, your Chiller will have new parts.

The new design incorporates a few cool changes:

  • The Connector is now compatible with the new Medela Pump In Style and similar new-style Medela pumps to allow for easy double-pumping.
  • The Upper Cup now has a polished window that shows the ounce and milliliter markings more clearly.
  • There are fewer ridges on the inside of the Connector to allow you to more easily capture every last drop of milk.
  • The Upper Cup and Connector can now hold up to 7 ounces when assembled for double-pumping or as a baby bottle.
  • The new Connector design and threading make it grippier and easier for us moms with small hands to unscrew.
  • Comes with Lifetime Warranty.

As always, please don't hesitate to reach out to us at if you have any questions about your Chiller, the new parts, or any other products that we offer.

Item was as described and shipped quickly. Also was packaged well.

So helpful

Wouldn’t make it through my work day without it

Wish I would have bought this with my first

So far so great. I’ve only used it a handful of times, as I’m not back to work from maternity leave, but so far I love it. I’m and EP mom, and was with my first too, this would have been so convenient. I work 12 hour shifts so the amount of pumping supplies really piles up quick, so I’m super excited to pump directly into the ceres and then have my milk cooled all day and close by, instead of having to worry about a communal refrigerator, people moving/leaving it out or constantly opening the door. Again, wish I would have gotten this the first time around, but glad I have it now, super pleased

Replacement Parts

They worked perfectly and I was glad to have them in stock when mine needed replacing. They shipped quickly to!

Caitlin Meneses

The replacement parts are perfect! The original one I had got mold on one of the seals (my bad for not taking it apart to clean often enough) but I’m so grateful there are these to replace it with!
