The small parts that make a big difference.
When you are pumping regularly, the details matter more than you expect. A worn duckbill valve. The wrong flange size. A bag that leaks at 3am. These are not small problems when you are already tired.

Any last questions?
Which breast pumps are compatible with Aaya Medical replacement parts?
Aaya carries parts compatible with Spectra (S1, S2, 9 Plus, Synergy Gold), Momcozy (M5, M6, V1, V1 Pro, V2, V2 Pro), and Eufy (E10, E20, S1, S1 Pro). The Duckbill Valves with Pull Tab extend compatibility further to Baby Buddha, Freemie, Hygeia, Medela Pump In Style Max Flow, Motif Luna, Zomee Z1 and Z2, and more. Each product page lists the exact pumps it works with, so you can confirm fit before you order.
What types of breast pump replacement parts does Aaya carry?
Duckbill valves, silicone diaphragms, backflow protectors, breast pump flanges, and tubing with adapter ends — plus milk storage bags and wide neck storage bottles.
How do I find the right flange size for my breast pump?
Measure your nipple diameter after a pumping session, when it's at its largest. Our Nipple Measuring Tool makes it easy to get an accurate measurement at home. Once you have your size, our flange product page includes a sizing chart so you can find the right fit. Still not sure? A lactation professional can help confirm.
How often should breast pump valves and parts be replaced?
It depends on the part. Duckbill valves every 2 to 3 months with daily pumping, sooner if suction drops. Silicone diaphragms every 1 to 3 months. Backflow protectors around every 6 months. Flanges every 3 to 6 months or when comfort or suction changes. Replace any part sooner if you notice visible wear or a drop in performance.
