Over time, milk residues can accumulate in the valves and membranes of your Medela breast pump. This can cause them to no longer seal properly. The pump then draws in air, resulting in reduced suction power. Therefore, it is crucial to regularly replace the valves and membranes of your breast pump – and the Medela Multipack makes this easy. Suitable for all Medela breast pumps. Package includes:

• 2 replacement valves
• 6 membranes.
