afontoto 17mm Flange Insert for S9/S12 Pro – 24mm to 17mm Silicone (2 pcs)

Overview

Meet the afontoto Flange Insert 17mm, a silicone adapter designed to retrofit 24mm shields for compatible wearable pumps. This 2-piece, transparent set helps you tailor the fit to your pumping routine, pairing soft, odorless silicone with a simple, everyday care routine. By downgrading from 24mm to 17mm, you gain a more personalized fit that can feel gentler during sessions without changing your pump hardware.

Comfort-first design

The insert is made from BPA-free silicone that feels soft to the touch and remains gentle against skin and milk collection components. The transparent material makes it easier to monitor alignment during pumping, helping you maintain a comfortable, steady seal.

Key benefits

• ✅ Custom fit by downgrading a 24mm shield to 17mm for a closer seal.
• ✅ Compatible with S9, S12, S9Pro, and S12Pro wearable pumps that use 24mm shields.
• ✅ BPA-free, odorless silicone ensures safe contact with breast milk components.
• ✅ Transparent design facilitates quick checks of alignment and seal during use.
• ✅ Easy to clean and sanitize: warm soapy water, steam, boiling water, or microwave-steam bags.

Real-world use and care tips

In daily pumping, this 17mm insert can offer a closer, more comfortable feel by reducing the shield’s effective diameter. During a session, monitor your nipple’s appearance to ensure it isn’t rubbing or feeling pressed inside the tunnel. This can help you decide if the fit is right for you and your pump.

Care and maintenance

• Wash after each use with warm soapy water.
• Rinse thoroughly and allow to air dry.
• Material is compatible with steam sanitation, boiling water, or microwave steam bags.
• Store in a clean, dry place between sessions.
