Pumping comfort and potential efficiency

With the right flange fit, you may experience more comfortable pumping, reduced nipple fatigue, and smoother milk expression. The 19 mm size is a widely used option for a balanced fit across many users.

Note: results vary by individual, and using components tuned to your setup can support a steadier pumping routine.
