• Six replacement
membranes
• Works with
all Medela breast pumps

If you've ever tried to operate your breast pump without one of these
membranes, you'll quickly discover it simply won't work. That's why it's
important to keep plenty of these extra membranes on hand. Compatible with all
Medela breast pumps, the membranes snap directly into the valves so they lie
flat. After each use, disassemble from the valves and wash in warm, soapy water.
Rinse in clear water and allow to completely dry.
