Product Description
Ensure your breast pump continues to function at its peak with the Maymom Silicone Membrane Diaphragm. Specifically engineered as a high-quality aftermarket replacement for Spectra S1, S2, and 9 Plus breast pumps, these membranes are essential for maintaining a closed pumping system. The diaphragm acts as a critical barrier, preventing milk from entering the pump tubing and motor while ensuring consistent suction strength throughout your pumping sessions.
Crafted from durable, food-grade silicone, these components meet strict safety standards, complying with both EU and United States FDA regulations for materials in contact with food. This set is fully compatible with Maymom backflow protectors, including long, medium, and short stem versions, as well as original Spectra backflow protectors. Regular replacement of your silicone membranes is a vital part of breast pump maintenance. Experts recommend swapping these parts every three to six months, or sooner if you observe a decrease in suction power or notice wear and tear. These diaphragms are easy to clean and can be safely sterilized in boiling water or steam to maintain hygiene for every use. Choose these reliable, imported components to keep your pumping routine efficient and sanitary.
