What weabout it
Since these small flaps are easy to lose, you’ll likely need some extras.

About this Product
  • Compatible with most Medela breast pumps
  • Necessary for pumps to function properly


These small flaps go inside your breast pump next to the valve, and they are really easy to slip down the sink when you’re washing them. Have some extras on hand if you’re pumping regularly.

Make sure to sterilize them before first use and then attach them to the breast pump valves per your pump’s instructions.


  • Material: BPA-free plastic
  • Not compatible with the Freestyle breast pump
