Seal Diaphragm

The diaphragms that go under the seal cap in your Liquid Shield Kit need regular replacement. Expect to replace diaphragms every 6 months of light use, i.e. if you're pumping just a few times a week, up to every month if you're pumping exclusively. 

Please note these diaphragms are not compatible with our universal backflow protectors. If you're looking for diaphragms for standard backflow protectors such as our universal backflow protectors or Spectra's, please buy our universal diaphragms.

All Pumpables parts in contact with your milk are free from BPA, phthalates and other nasties.
