Spectra’s total compatibility guide for bottles, breastshields, and more

Your Spectra breast pump comes with everything you need to double pump, including two sets of tubing, breastshields, valves, and bottles, but if you have bits and pieces already at home, then you may want to know what is compatible with what. Below is a guide on everything we know about compatibility. Let us know if we missed anything.

Bottles that fit Spectra breastshields

Spectra breastshields are wide neck, so you should be able to use any bottles coming with a standard wide neck. This includes:

  • Pumpables
  • Avent Classic
  • Avent Natural
  • Minbie glass and plastic

You can use narrow neck bottles like Medela bottles if you use Spectra’s wide neck to narrow neck adaptor.

    I am wondering if Dr. Browns *glass* wide neck bottles would fit the spectra breast shields? Thanks!

    • Spectra Team Australia says:

      Hey Stephanie, unfortunately they do not.

      They are not standard wide neck bottles as they allow for the piece to go in the bottle to help with managing the air.There are a few other brands of plastic bottles that fit Spectra breast shields. These include:
      Avent (Natural and Classic)
      Difrax-S wide neck, and
      Happy Baby bottles from Coles. (These are slightly tighter, but if you are firm with the bottles when assembling them, they will fit without leaking)

      If you prefer glass bottles, we understand that Mam and Minbie glass bottles will fit directly onto your wide neck shields, and Lifefactory bottles will fit with a wide to narrow neck adaptor.

      Hope this helps. 🙂

      Hi Melanie, they should fit as the Avent is pretty standard with their necks. Can you let us know how you go?

    • Spectra Team Australia says:

      Hey Madeline, unfortunately it is not.

      The Tommee Tippee are an extra wide neck bottle. 🙁

      Let us know if we can help with anything else. 🙂

            I’ve managed to adapt the Closer to Nature bottle to the Spectra S2 Pump. I bought a ‘Tommee Tippee Closer to Nature Standard Neck Breast Pump Adapter’ from Amazon in America (as seen here: https://www.tommeetippee.us/product/breast-pump-adapter). I also bought a ‘Spectra Small Cap Converter’. (also called a Spectra Neck Adaptor – Wide Neck Shield to Narrow Neck Bottle). So in order from top to bottle I have fitted: Spectra Wide Neck Breastshield Set, attached to Spectra Small Cap Converter, attached to Tommee Tippee Closer to Nature Standard Neck Breast Pump Adapter and then attached to a Tommee Tippee Closer To Nature bottle. And it’s working really well. The fit between the Spectra Small Cap Converter and the Tommee Tippee Closer to Nature Standard Neck Breast Pump Adapter is a bit tight so needs a strong hand to separate the two but otherwise this set up is excellent.

        • Katie says:

          You can use two adapters at once to use Tommee Tippees. The wide to narrow adapter to fit Medela. Then the Medela – Tommie Tippee adapter.

    Would the spectra pump fit with Nuk bottles? The bottles look like they are wide neck, but I’m not sure if it is a standard size or not?

    • Spectra Team Australia says:

      Hi Ilana, I believe they are different to the standard wide neck, so no. 🙁

      If you do try it and they work, will you let us know? Bottle manufacturers are always changing things with their products so things can and do change. 🙂

    Hi, will a Spectra nipple and cap fit the Avent Natural bottles? The Spectra bottles are only 5 oz and I need at least 6 oz. Thank you!

    • Spectra Baby Australia says:

      Hi Angela, feedback from other mums share that they do work, but occasionally Avent bottles have changes during their manufacturing batches in them so this could change. 🙂

    • Spectra Team says:

      Hi Danica, are they standard narrow neck bottles or wide neck?

      If wide neck they will not work and we do not know of an adaptor, but if narrow neck, you can use the wide to narrow neck adaptor and they will work.

      You can find the adaptor here -https://spectra-baby.com.au/shop/accessories/spectra-shield-adapters-wide-neck-shield-to-narrow-neck-bottles/
