Hranio 21mm Flange Insert 6PC – Compatible with 21mm Flanges & 24mm Shields (Spectra/Medela/Elvie/Willow)

Meet the Hranio 21mm Flange Insert 6PC, a silicone set designed to adapt 21mm flange systems to a wide range of shields and wearable pumps. The six-piece pack gives you ready-to-use inserts that are easy to swap as your needs change.

Built from transparent, BPA-free silicone, these inserts are designed to cradle the nipple area with a gentle, flexible fit. They’re intended to be used with most 24mm shields, which means compatibility with a broad lineup of popular pumps and shield brands. This approach can help you tailor your flange system without buying multiple full-size flanges.

Why this matters for daily pumping

• Compatibility: Works with most 24mm shields and flanges, and with S9 Pro/S12 Pro/S9/S12 wearable pumps, as well as brands like Momcozy, Medela, Spectra, Elvie, Willow, and TSRETE.
• Comfort and control: The soft silicone and transparent design support a comfortable pumping experience and easy visual inspection of the fit.
• Convenience: Six inserts in one pack means you can rotate, try, and replace without interrupting your routine.
• Safety and materials: BPA-free silicone ensures you’re avoiding common concerns with plastics in the pumping setup.

Care, fit, and usage tips

Cleaning after each use is simple—wash with warm soapy water, then rinse thoroughly to keep the silicone clear and ready for next session. A light dab of coconut oil or nipple butter can help reduce friction and ease placement, though use as you prefer.

• Replacement timing: Monitor the flange insert, as fit affects comfort and efficiency; consider replacing every 1–2 months with regular use.
• Fit checks: The size is crucial for both comfort and pumping efficiency; look for signs of irritation or swelling and adjust accordingly.

Real-world use scenarios

Whether you’re starting your day with a quick morning pump, managing a night-time session, or sharing a setup with a partner, the Hranio inserts offer a flexible path to a better personal fit. They’re designed to support continuity in your pumping routine, especially when you’re experimenting with different flange systems.

Bottom line

Hranio 21mm Flange Insert 6PC adds versatility to your pumping toolkit. While not a medical device, the inserts present a practical option to customize fit, maintain comfort, and keep your gear clean and compatible with a broad range of shields and pumps.
