Review: Perfect Fit for My Momcozy Pump! - These replacement duckbill valves and silicone parts were exactly what I needed! They fit perfectly with my Momcozy pump and worked just as well as the original parts. The suction was strong and consistent, and I noticed no difference in performance. I love that they’re easy to clean and feel durable — definitely a great value for the price. It’s such a relief to have reliable spare parts on hand, especially during those long pumping days.
