Calling all Elvie pump users! These Tbuymax replacement duckbill valves are exactly what you need to keep your wearable breast pump working like new. This pack comes with 6 valves that are fully compatible with the Elvie wearable breast pump (just note - they don't work with the Stride model). They create the same great suction as the original OEM parts but at a much more affordable price. The closed system design means milk never contacts the pump motor, protecting your investment. They're made from BPA-free, food-grade materials that are completely safe for you and your baby. Cleaning is a breeze - just use soapy water and rinse well (avoid hard brushes that might damage them). When your original valves start wearing out or losing suction, these are the perfect replacement to restore that like-new performance. Having extras on hand means you're never stuck without your pump when you need it most. They come factory sealed for hygiene and are ready to use right out of the package. For breastfeeding moms who rely on their Elvie pump, keeping these essential replacement parts stocked is just smart planning - because when you need to pump, you need your equipment working perfectly!
