Meet the authentic Momcozy wearable breast pump flange insert designed specifically for S9 Pro and S12 Pro models. This 27mm single-sealed flange is an original Momcozy replacement part, created to fit snugly with your S9 Pro or S12 Pro wearable pump and support a smooth pumping routine. Because these parts contact breast milk, choosing BPA-free silicone helps you feel confident about your baby’s milk.
What you’ll notice in real use is a compact, soft-touch component that feels comfortable against the skin while delivering a reliable seal. In daily use, many moms appreciate the quiet, steady workflow of wearing the pump with the right flange size. This set is intended as a genuine, compatible replacement so you can maintain your preferred setup without hunting for mixed parts.
Care and maintenance matters. After each session, wash the parts with warm, soapy water and rinse thoroughly. For disinfection, you can use boiling water or steam at around 100°C (212°F). This simple routine helps maintain hygiene and extends the part’s usable life when handled gently.
Longevity and replacement: washable parts are intended to be used over time, with expected service life of 1-3 months. If they become deformed or yellowed after long use, replacing them in time helps maintain fit and performance.
In short, these Momcozy original replacement accessories are designed to support moms with a dependable, store-ready option for S9 Pro/S12 Pro pumping. They reflect the brand’s commitment: a practical kit that helps you pump wherever you are, with the flexibility to adapt as your needs change. While results vary by person, the right-fit flange can contribute to a more comfortable pumping session and a smoother routine.
Q: Are these flange accessories compatible with all Momcozy pumps?
A: These accessories are designed for S9 Pro and S12 Pro wearables, not for the S9/S12 standard pumps.
Q: How often should I replace the replacement flange?
A: Replace when deformed or yellowed; typical service life is 1–3 months with regular use.
