Liquid Seal Diaphragm [Pack of 2]

11 reviews
Size Guide

Pack of 2 replacement seal diaphragms for use with your Pumpables Liquid Shield Kit.


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.

    Affordable replacements.

    It’s great you can get replacement parts and they are affordable. Low four kit has saved my pumping journey.

    Durable diaphragms. I haven’t had to replace them yet after 3 weeks of usage as an exclusive pumper.

    It’s perfect for use with the liquid kit. The clear design allows me to see if there is any problem with the diaphragm

    Love the new version of the diaphragm!! It reduces the noise and i feel like it sticks better n helps reduce the noise.
