Pumpables Universal Backflow Protectors provide backflow protection for your breast pump. Comes in a pack of 2 full backflow protector sets.
The Pumpables Universal Backflow Protector is a little champion, sitting between your breastshield and tubing and making sure no milk can backflow down the tubing and potentially cause issues inside your pump motor. Breast pumps that have no backflow protection ("open systems") are prone to mould build up inside tubing and pump - which is no good for the pump and definitely no good for your precious milk!
Whether or not you choose the short stem or long stem sizing option will depend on the breastshield that you are using:
Note - if you want to be able to swap between Spectra-style and Medela-style shields, choose the short stem option and also purchase the Pumpables Spectra-Medela Adaptor (sold separately). The short stem will not directly fit to Medela breastshields - you need the adaptor.
Each pack comes with 2 complete backflow protector sets. All Pumpables parts are free of BPA and other nasties.
All Pumpables parts in contact with your milk are free from BPA, phthalates and other nasties.

Using the correct sized breastshield is really important to have the most comfortable pumping experience. We are all different shapes and sizes, and it can be really hard to know which breastshield size you will be when you start pumping.
A baby's mouth compresses a nipple evenly all over the nipple and areola, whereas a breastshield flange is rigid. As a result, if your flange is too large, the areola will 'bunch' up into the flange, which can cause pain and nipple trauma. You want the flange to be just wide enough to fit the base of your nipple, preventing the areola from being able to get pulled into the flange.
Using our nipple ruler is a good place to start.
If you've used the ruler and you're still not sure, we're happy to help with another opinion. If you'd like us to give you feedback, please take a photo of your nipple through each size so we can compare how each fits. You can send your pics through the 'chat' function at bottom right of the page.
For extra help, send a video of your nipple in the flange while you're pumping through our Fitting Room.
