BALIME Replacement Duckbill Valves & Silicone Membranes for Spectra S1/S2/9 Plus – 6 Valves + 6 Membranes (Not Original Accessories)

Meet BALIME's 12-piece pump parts set, designed to fit Spectra S1, S2, and 9 Plus pumps. This value pack includes 6 duckbill valves and 6 silicone membranes, offering a convenient upgrade that helps shield your pump tubing from milk entry and reduce the need for frequent cleanups. While not official Spectra accessories, these parts align with the fit and function you expect from your pumping routine, and are built to be lightweight and portable for life on the go.

Compatibility and fit are at the core of this kit. The duckbill valves and silicone membranes are engineered to align with Spectra flanges, creating a barrier that helps keep the tubing drier and the pump easier to maintain. You can tuck these parts into a diaper bag, purse, or work tote for pumping at home, at the office, or during travel—supporting a smoother, more flexible routine wherever you are.
