No. Although your NEW Pump in Style with MaxFlow Breast Pump may seem to physically "fit" the original PersonalFit Connectors, they are NOT compatible.
Pump in Style with MaxFlow is only compatible with Medela's PersonalFit Flex™ Connector. Our PersonalFit Flex Connectors create a closed system at the pump kit, designed to prevent milk back-up into tubing. Use with other connectors could cause irreversible damage to your breast pump. Additionally, if using a non-compatible connector, you may experience vacuum levels outside of our clinically safe vacuum ranges.
