BDICOVE 4Pcs Flange Insert 21mm – Wide Compatibility with Momcozy, Spectra, Medela & More

BDICOVE Flange Insert 21mm Kit — Comfort, Compatibility, and Convenience

Designed to adapt to a wide range of breast pump brands, the BDICOVE 4Pcs Flange Insert 21mm kit gives you flexible sizing without needing separate parts from each brand. The inserts are made from frosted, transparent, food-grade silicone and are BPA-free, aiming to feel soft to the touch while creating a reliable seal around the flange. This kit is ideal for caregivers who use more than one pump or who are navigating changes in nipple size over time.

What makes this kit stand out is the breadth of compatibility. In practice, you may find it works with popular models from Momcozy (M5/M9/M6/S12 Pro and V2 Pro variants), as well as brands like Spectra, Medela, eufy, Elvie, Lansinoh, Paruu, and others. If you commonly shield your pump with a 24mm insert, these 21mm options can help you find the right fit without changing the entire pumping setup.

Customized Comfort Across Stages

Nipple size can shift as you progress through feeding stages. The kit provides multiple sizes (13mm, 15mm, 17mm, 19mm, 21mm) so you can discover a snug, comfortable seal. If you’re uncertain about sizing, a 10-piece option is recommended to experiment and determine your best match.

• Multiple sizes support a personalized fit for sustained comfort.
• Soft silicone aims to ease contact with the skin while preserving pump usability.

Engineered for Enhanced Pumping Experience

The soft, flexible inserts are designed to minimize pressure points while helping to optimize the pumping rhythm. While individual results vary, many users report a calmer pumping session and a smoother feel at the flange edge.

• Reducing discomfort can contribute to more comfortable sessions.
• Potentially helps you maintain a steady pumping pace and efficiency.

Safe, Easy to Use and Clean

Crafted from frosted, transparent silicone, the inserts are BPA-free and food-grade. They’re designed for easy handling during use and regular cleaning, which can be done with warm soapy water. The material is suitable for boiling or steaming if you follow proper guidelines.

• Food-grade silicone for safety and quality.
• Dish- and boil-friendly for a thorough cleanse as part of routine care.

Care, Replacement, and Longevity

For best results, wash after each use and ensure thorough rinsing. Boil or steam around 100°C (212°F) when disinfection is needed. Consider replacing inserts every 1–2 months to maintain fit and hygiene as sizes may drift over time.

Whether you’re juggling multiple pumps or seeking a more comfortable, tailored fit, this BDICOVE kit offers a practical solution that aligns with busy daily routines without promising guarantees. Try the different sizes and discover what feels best for you.
