Quick Answer
Spectra CaraCups are compatible with most Spectra breast pumps and several other brands that use a standard 24mm or 28mm flange connection. However, compatibility depends on your pump's tube system and flange size. Always check your pump model against the CaraCups specifications before purchasing.
How Compatibility Works
CaraCups replace traditional bottles and flanges with a lightweight, BPA/DEHP-free insert that sits inside your bra. They connect to your pump via tubing and a backflow protector. The key compatibility factor is the flange opening size: CaraCups are available in 24mm and 28mm options. If your pump uses a different flange size, you may need an adapter or a different insert.

Which Pumps Work with CaraCups?
Spectra states that CaraCups work with all Spectra breast pumps, including the S1 Plus, S2, 9 Plus, and Synergy Gold. They also work with many other major pump brands that use standard tubing and flange connections. However, pumps with proprietary connectors or non-standard tubing may not be compatible. If you are unsure, contact the pump manufacturer or Spectra support with your pump model number.
What About the Wearable Feeding & Accessories Kit?
The Spectra Wearable Feeding & Accessories Kit is designed specifically for the Spectra Premier Wearable Breast Pump. It includes a wearable milk container, secure cover, and slow-flow nipple for feeding directly from the container. This kit is not a replacement for CaraCups and is not intended for use with other pumps. If you own a Premier Wearable Pump, this kit simplifies milk collection and feeding in one set.

Frequently Asked Questions
Can I use CaraCups with a manual pump?
CaraCups are designed for electric breast pumps with tubing. Manual pumps typically do not have the necessary tubing connection, so they are not compatible. Stick with electric pumps for hands-free inserts.
Do I need different flange sizes for CaraCups?
CaraCups come in 24mm and 28mm flange sizes. Measure your nipple diameter and choose the size that matches your pump's flange requirement. Using the wrong size can reduce suction and comfort. Measure first, then select the correct flange size.
Are CaraCups dishwasher safe?
Spectra recommends hand washing CaraCups with mild soap and warm water. Dishwasher cycles may warp or damage the plastic over time. Always air dry thoroughly. Hand wash to extend the life of your inserts.
Will CaraCups work with my Medela or Lansinoh pump?
CaraCups are compatible with many pumps that use standard 24mm or 28mm flanges and tubing. Medela and Lansinoh pumps often require an adapter because their tubing connectors differ. Check the product listing or contact Spectra for specific adapter needs. An adapter may be needed for non-Spectra pumps.
Product Facts
- CaraCups Wearable Milk Collection Hands-Free Inserts: CaraCups make hands-free pumping easy by placing inserts in the bra, compatible with all Spectra pumps and other brands. They are lightweight, BPA/DEHP-free, and use a true-closed system. You can pump hands-free without buying a new pump, but you must verify flange size and tubing fit for non-Spectra models.
- Wearable Feeding & Accessories Kit: The Wearable Feeding & Accessories Kit is designed for the Spectra Premier Wearable Breast Pump and includes a milk container, cover, and slow-flow nipple. This kit is pump-specific and not a universal accessory. It is ideal if you already own the Premier Wearable Pump and want an all-in-one collection and feeding solution.
