Liquid Seal Diaphragm [Pack of 2]

16 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.

    Love the liquid kit

    I absolutely love the liquid shield kit overall. My one complaint is that these diaphragms sit loosely in their designated spot and are not secure until the seal cap is attached, so they can easily fall off while adjusting the pump parts. I ordered extra diaphragms so I would always have a clean one ready to go in the event I dropped one, which happens not uncommonly even when being careful. I wish the diaphragms attached directly to prevent this from happening.
