Some moms want to use Medela parts with their Spectra pump, or they may want to use Spectra parts with their Medela pump. Did you know that you can hack your Medela and Spectra pumps and pump parts together? All you need are a few simple inexpensive adapters for your pump!

It can be so convenient to have all your pump and pump parts be interchangeable.

One reason these adapters were useful for me was because I had several pumps. I was constantly switching between the Medela PISA, the Spectra S2, the Spectra S9, and the Medela Symphony.

Using these adapters I was able to save money because I didn’t need to buy extra pump parts for each pump.

I also saved time because I didn’t have multiple sets of bottles to clean.

But most importantly, I saved a lot of breast milk! This is because I wasn’t losing milk when transferring milk. It was painful anytime I lost a few drops when I tried pouring from the bottles I used for pumping into the bottles I used for feeding.

There are three major questions to ask yourself when figuring out which is the right adapter for each situation.

  1. Keep in mind which pump you have,
  2. Keep in mind which flanges you want to use, and
  3. Remember which bottles you want to pump into.

There are generally two types of adapters that can be used to connect different brands of pumps and pump parts

  1. Adapters that connect tubing to flanges, and
  2. Adapters that connect flanges to bottles

Adapters To Use If You Have A Medela Pump

If you have a Medela pump, the main thing to pay attention to is where the tubing attaches to the flanges.

Can You Use Spectra Parts With Medela Pump?

The answer is yes, you can use Spectra parts with a Medela pump if you have the correct tubing. This is because the tubing that comes with the Medela Pump In Style (PISA) will not fit directly into the Spectra backflow protector.

If you have a Spectra pump and a Medela breast pump (like the popular Medela PISA), you may wonder how to get your pump parts to work with both pumps.

This is the tubing you will need to connect Spectra parts with a Medela pump.

How To Use Spectra Parts With Medela Pump

In order to use Spectra Parts With A Medela Pump, you will need an extra set of tubing. This is because the tubing for Medela will not connect directly to the Spectra flange and backflow protector unless you cut the tubing.

The best way I found to do this is to buy this inexpensive tubing. I’ve tested it and it fits well to connect my Spectra flange and backflow protectors to my Medela PISA. It comes with a lot of tubing, and you can just cut it to the length that you need.

It is also possible to just cut your Medela PISA tubing, but I prefer not to do this.

It is definitely worth it to get an extra set of tubing. This way, you still have your original tubing to use when you want to pump with your Medela flanges and Medela pump.

It is also a good idea to have extra tubing on hand because it needs to be replaced frequently to prevent condensation in the tubing. If water (or milk) gets into the tubing and isn’t cleaned out, mold can start to grow.

If you want some more info on this, you can check out my in-depth articles on replacing pump parts, and preventing mold in pump tubing.

How To Use Spectra Flanges With A Medela Pump

To use Spectra flanges with a Medela pump, you will need to decide if you want to use the Spectra backflow protectors.

A benefit of the backflow protectors is that they keep milk out of the tubing and pump motor. These are what make the Spectra pump a closed system.

You will also need a set of tubing which connects the Spectra flange and backflow protector to the Medela Pump.

If you want to connect Spectra flanges with a Medela Pump, then use this tubing (link to Amazon).

Here are the instructions:

  1. Take the tubing and cut it to the length that is comfortable for you (usually about 2-3 feet).
  2. If you want to double-pump, cut another piece of tubing the same length.
  3. Connect one end of the tubing to the Spectra backflow protector.
  4. Connect the other end of the tubing to your Medela PISA pump.

That’s it! Now you can use your Spectra flanges with your Medela Pump!

This works best for the most popular Medela pump, the Medela Pump In Style Advance. If you want to use it with a Medela Symphony, then purchase this extra set of pump tubing and cut off the end that normally connects to the Medela flanges.

Do Spectra Valves Fit Medela?

Yes, Spectra Valves Fit Medela flanges. Medela valves and membranes also fit on Spectra flanges. They are interchangeable if you are using the two most common Medela pumps, like the Medela Pump In Style Advanced or the Medela Symphony.

I actually preferred to use duckbill valves regardless of if I was pumping with Spectra or Medela flanges.

The duckbill valves definitely provided better suction than the valves and membranes that came with my set of Medela pump parts. They were also more durable and did not stretch out and wear out as quickly as valves and membranes.

Here is a link to my favorite duckbill valves (at Amazon). They worked with both my Spectra flanges and my Medela flanges.

Using Spectra (or Avent) Wide Mouth Bottles With a Medela Pump

If you want to use Medela flanges and pump directly into wide-mouth bottles, then you will need an adapter. You may have a Medela pump from insurance, but your baby prefers different bottles. If this is the case, you can still pump directly into bottles using the correct adapter.

Another reason you might want to pump into wide-mouth bottles is if you pump more than 5 ounces per side during a pumping session. Avent makes 9 ounce and 11 ounce bottles that you can use if you have a pumping session where you express a lot of milk.

Some of the bottles this adapter is compatible with are:

  • Avent Classic
  • Spectra bottles
  • Standard-size wide mouth bottles

This is the best adapter to use if you have a Medela pump and flanges but want to pump into the wide-mouth bottles.

Pumping Directly Into Comotomo Bottles

If you have a Medela pump and flanges, you can use an adapter to pump directly into Comotomo bottles. You may have noticed that the opening for the Comotomo bottles is much larger than the opening for the standard Medela bottles. An adapter will connect the Medela flanges to the Comotomo bottles.

This is the best adapter that works with a Medela pump and flange set and Comotomo bottles.

This is the best adapter to use a Spectra pump and flange set with Comotomo bottles. As a bonus, it also works with Boon nursh bottles if those are the bottles that your baby prefers!

Adapters To Use If You Have A Spectra Pump

There are also several adapters available if you want to pump with a Spectra pump. I used these adapters often.

This is because I started out pumping with a Medela pump and buying Medela pump parts, and later on I switched to pumping with a Spectra.

You can read more about the right Spectra bottles adapters to use in this article.

Do Medela Flanges Fit Spectra?

Medela flanges will fit the Spectra pump if you use a special adapter. This is because the Spectra backflow protectors and Medela flanges connect to the pump tubing in different ways.

This is my favorite adapter to use Medela flanges with a Spectra pump. I wrote an entire article on 3 different ways to hack your Medela flanges with a Spectra pump. You can check it out below for all of the details.

Will Medela Bottles Fit Spectra?

Yes, Medela bottles will fit a Spectra pump as long as you use the correct adapter. This is because the Medela bottles have a narrow mouth and Spectra flanges fit wide-mouth bottles.

Using this adapter will allow you to pump with Spectra flanges directly into your Medela or Dr. Brown bottles. This will save you from needing to buy new bottles!

It is also a huge time saver when you can pump directly into the same bottles that your baby drinks from! It means fewer bottles to wash and store on your countertop.

How To Use Medela Bottles With Spectra Pump

If you want to connect Medela bottles to a Medela flange and Spectra pump, then use this adapter (link to Amazon).

Medela flanges fit narrow-mouth bottles, but Spectra bottles are wide-mouth. This is why you need an adapter to connect between the Medela bottles and Spectra pump.

Here are the instructions:

  1. Assemble your Medela pump parts
  2. Use Medela tubing to connect the Medela flange with the Medela pump
  3. Use this adapter to screw the Medela flange onto the Spectra bottle

Spectra Wide To Narrow Adapter

Spectra flanges can also be connected to any standard size narrow-neck bottles, such as Dr. Brown’s. In order to use them, you will need to use an adapter.

This is the best adapter (link to Amazon) to connect Spectra flanges to narrow mouth bottles.

Spectra Adapter for Dr. Brown Wide Neck Bottles

There currently is not a good adapter to pump directly into Dr. Brown’s wide neck bottles. This is because Dr. Brown wide neck bottles are not a standard size.

If you want to pump directly into wide-neck bottles, I’d recommend using these Avent bottles. These bottles fit directly onto the Spectra flanges without needing an adapter!

Spectra Bottle Adapter for Tommee Tippee Bottles

If you want to pump directly into Tommee Tippee bottles with your Spectra pump, then you will need a set of adapters. This is because the Tommee Tippee Closer To Nature bottles are an extra wide-neck bottle size.

You will need both of these adapters to pump with a Spectra pump into Tommee Tippee bottles.

First, use this adapter to make your Spectra pump compatible with Medela bottles.

Second, use this adapter to make your Medela adapter compatible with the Tommee Tippee bottle compatible with a Medela pump.

Even though you use two adapters, it is worth it so you don’t lose any milk when transferring from pumping bottles to feeding bottles.
