Spectra Membrane for Backflow Protector

The Spectra Membrane for Backflow Protector from Fed is Best is an essential spare part designed to maintain strong suction, hygienic operation, and peak performance in your Spectra breast pump. These small but important silicone membranes help create a secure seal inside the backflow protector, ensuring that milk is safely separated from the motor for reliable, contamination-free pumping.

Reliable performance for every session

Each Spectra Membrane works to regulate air pressure inside the pump, supporting smooth and efficient milk expression. Over time, the membrane can lose elasticity, which may reduce suction strength and pumping comfort. Replacing this component regularly keeps your breast pump operating just as effectively as the day you bought it.

Safe, durable, and easy to replace

Made from high-quality, food-grade silicone, the Spectra Membrane for Backflow Protector is completely free from BPA and other harmful chemicals. It’s safe for both mum and baby, and built to withstand frequent sterilisation. The flexible design makes replacement simple – just separate the two halves of your Spectra backflow protector, insert the new membrane, and reassemble.
