Overview

This product is a Momcozy original replacement accessory set designed exclusively for the S9 Pro and S12 Pro wearables. The standout feature is a 27mm double-sealed flange that aims to create a secure seal during pumping, helping to minimize leaks and support a smooth pumping rhythm.

Made from BPA-free, food-grade silicone, these components are intended to be gentle on contact surfaces while remaining easy to clean after use.

Note that this set is not compatible with the original S9/S12 base models, so please confirm model compatibility before purchasing.

Key benefits for S9 Pro and S12 Pro users

• Enhanced seal with 27mm double-sealed flange: engineered to reduce leakage and to support a steady pumping session.
• BPA-free silicone: safe contact with breast milk and peace of mind during daily use.
• Designed for real-life use: easy cleaning and durable materials that stand up to regular handling.
• FSA/HSA eligible: a potential financial pathway for eligible customers.

Care, use, and maintenance

• Cleaning: after each session, wash components with warm soapy water and rinse thoroughly.
• Disinfection: use boiling water or steam at about 100°C (212°F) to sterilize parts as needed.
• Service life: washable parts typically last 1–3 months; replace if deformation or yellowing occurs.

Tips for the best fit and ongoing comfort

Flange size matters for comfort and efficiency. If you notice nipple rubbing or pressure against the flange channel, consider adjusting to the correct size insert to maintain a comfortable seal. Keep model compatibility in mind to ensure seamless operation with your Momcozy S9 Pro or S12 Pro system.
