Parner Flange Inserts 19mm for 24mm Shields – 6PCS, Wearable Breast Pump Fit

Enhance Comfort and Custom Fit with Parner Flange Inserts

Parner Flange Inserts are soft, transparent silicone adapters designed to reduce a 24mm shield’s tunnel down to a comfortable 19mm effective size. This creates a gentler fit without changing your pump’s overall compatibility, offering a flexible option for wearers who want a more tailored pumping experience.

Wide Compatibility Across Brands

The inserts are built to work with most 24mm shields or flanges compatible with popular models, including Momcozy S9/S9 Pro/S10/S12/S12 Pro, TSRETE, Medela, Spectra, Elvie, Willow, BelleBaby, Motif Luna, Ameda, and more. Note: not suitable for 27mm shields.

• Soft, food-grade silicone for a comfortable feel
• BPA-free safety for peace of mind
• Easy sanitation options: water steam, boiling water, or microwave steam bags
• Thorough cleaning recommended after each use

Size Options, Replacement, and Maintenance

This 6-piece set includes multiple sizes to tailor the fit as needed. The data note that sizes available include 13/15/17/19/21 mm, enabling you to find the best match for smoother milk drainage. Some mothers may experience nipple swelling during pumping, so monitoring fit and comfort is advised. Replace inserts every 1–2 months or if deformation or discoloration appears.

• Six inserts in multiple sizes for customizable fit
• Designed to adapt 24mm tunnels to a 19mm effective size
• Monitor nipple appearance and comfort during pumping
• Replace on a regular schedule to maintain performance

Easy to Use and Care for Your Gear

Use the inserts with your compatible 24mm shield, then clean after each session. The silicone material supports straightforward sanitization via steam or boiling methods, helping you keep gear ready for your next pumping session.

• Place inserts securely into the shield before pumping
• Sanitize after use and wash with warm, soapy water
• Inspect for wear; replace if deformed or discolored
• Keep them away from prolonged heat exposure to preserve shape

Safety, Support, and Real-World Use

Parner backs the inserts with careful testing and a support team ready to help if you receive an incorrect size or need installation guidance. While these inserts may offer a more comfortable fit for many users, they describe possibilities rather than guarantees, and individual results may vary.
