Momcozy Flange Insert 21mm – 4-Pack for 24mm Breast Pump Flanges

Overview

The Momcozy Flange Insert 21mm is a silicone accessory designed to adapt a 21mm inner size to many 24mm flange/shield systems. This 4-pack provides convenient spares for multiple pumping sessions, travel, or quick size adjustments as your comfort needs evolve.

Fit, compatibility, and materials

• Four 21mm inserts are compatible with most pumps that use a 24mm flange, helping you tailor fit without changing the pump body.
• Made from BPA-free, food-grade silicone, ensuring that breast milk contact remains safe and clean.
• FSA/HSA eligible as a Momcozy original part, offering flexible purchasing options.

Care and sanitation

• Easy to clean—wash with warm soapy water after use and rinse thoroughly.
• For thorough sanitation, you can boil or steam the inserts at about 100°C (212°F).

Comfort and real-world use

Size matters for comfort and efficiency. The 21mm insert is designed to support a comfortable pumping experience while allowing you to observe nipple appearance during pumping. If the fit feels off or swelling occurs, consider switching to the right size flange insert.

In daily routines, the slim insert can blend with the outer flange for a steady rhythm, reducing pressure points and helping you maintain a gentle, natural pumping pace. When traveling or juggling a busy day, keeping a spare 21mm insert in a small bag helps you stay prepared without compromising your routine.

Quality and user care

Momcozy designs pump parts with moms in mind, aiming to support everyday routines and the journey of parenthood. These inserts reflect the brand’s commitment to practical, reliable accessories that travel well and fit a variety of pumping setups.
