Breast Shield (PersonalFit Flex) MEDELA 30 mm for breast pump

The PersonalFit Flex 30 mm breast shield by MEDELA is a replacement or alternative flange designed for compatible breast pumps. It features a 30 mm silicone cushion with a flexible rim that adapts to the shape of the areola to provide a more individualized fit. The shield is intended for direct connection to compatible Medela equipment and is suitable for mothers who need a different flange size to improve comfort and milk removal efficiency.

Advantages

The soft silicone cushion with a flexible rim reduces localized pressure on the breast and helps create a comfortable seal during expressing. A precisely shaped tunnel guides milk flow efficiently from the breast to the connector, minimizing backflow when used with compatible components. The shield is lightweight, easy to handle and designed for routine cleaning and sterilization according to manufacturer instructions.

Suitable for

• Mothers who require a 30 mm flange to match their areola diameter
• Users seeking a more comfortable seal compared with rigid flanges
• Replacement of worn or damaged breast shields on compatible Medela pumps
• Expressing with single- or double-pump configurations when compatible

Key specifications

• Flange inner diameter: 30 mm (silicone cushion measurement)
• Material: medical-grade silicone (cushion); hard plastic connector parts compatible with Medela systems
• Compatibility: designed for direct use with compatible Medela pump systems and connectors
• Design feature: flexible rim for adaptive fit and reduced pressure points

How to use

Before first use and after each use, inspect the breast shield for damage and clean according to the pump manufacturer’s cleaning and sterilization instructions. Attach the PersonalFit Flex 30 mm breast shield to the compatible connector or bottle following the pump user manual, ensuring a secure fit. Position the flange over the breast so the nipple sits centrally in the tunnel and start the pump at a low suction setting, increasing gradually to a comfortable level. Monitor fit and comfort during expressing and stop if pain or persistent discomfort occurs.

Usage recommendations

Measure your areola to confirm that the 30 mm flange provides the correct fit; an improperly sized flange can reduce milk removal efficiency and cause discomfort. Use the PersonalFit Flex shield with compatible Medela collection components and follow manufacturer guidance for cleaning, sterilization and replacement intervals to maintain hygiene and performance.
