Got Medela? You are in the right place! Here you will find replacement parts and accessories for your Medela Pump.
Note: Most Medela parts are compatible with all Medela Pumps. The exceptions are the Freestyle pumps and Hospital grade pumps. Those may have some unique parts. I have flagged a few items that are different.
If you are not sure about a part for your model or want to have me double check, then please drop me a comment on this page and I will help you out! The last thing I want is for you to have a part you can’t use.
Flanges / Breastshields
All Medela pumps are compatible with the Medela Breastshields. Medela offers a Standard Breastshield which comes included with most pumps in a size medium. They also feature their PersonalFit Breastshields which allows you to select your size.
The PersonalFit Breastshield is two pieces versus the Standard which is just one. So if you purchase the PersonalFit, you will also need to purchase the 2nd piece which is called a Connector if the set doesn’t come with it. Both the PersonalFit and the Standard Breastshields require the Valve and Membrane as well.
Confused? Follow my easy steps below to build your Breastshield!
Step 1: Choose Either a PersonalFit Breastshield OR Standard Breastshield (NOTE- If you have a Freestyle Pump, then you need to choose a PersonalFit Breastshield, the Standard will not fit)
Step 2: Choose a Connector if you chose a PersonalFit Breastshield (NOTE- The Freestyle Pump has a special connector that is listed below, be sure you chose the one titled Freestyle)
Step 3: Select Valve and Membranes. They fit both the PersonalFit connectors and Standard Breastshields. You need one valve per Breastshield but I would suggest getting several extra membranes as you will replace those often.

Pump Replacement Tubing
Your Medela pump will come with the appropriate tubing (the plastic tube that connects the Breastshield to the pump motor) but this is a part that you will want to replace every few months. So pick up an extra or two so you have it on hand when you need to replace it.
Please note that each pump will have specific tubing. The most common are listed here. If you are unsure what type of tubing you need, please feel free to drop me a question on this page and I will help you out.
Medela Bottles and Milk Storage
Medela bottles are easy to use and clean. All listed are compatible with Medela Pumps and you can pump directly into the bottle. Add a nipple and you are good to go! Or put the cap on and store for later! So rather you need a few bottles or a whole set, you’ve got options.
Be sure to check out the Medela Calma Nipple. It is designed to mimic the breast and is a great option for going back and forth between bottle and breast.
