Momcozy Flange Insert 19mm for M9*4

Momcozy Flange Insert 19mm for M9*4 fine-tune your expression comfort and maximize your milk output using the Momcozy 19mm Flange Inserts Multi-Pack. Specifically curated for the next-generation Momcozy M9 Mobile Flow™ series and backward-compatible with legacy collection cups,

When utilizing the M9 pump’s high-efficiency 3rd-Gen motor (delivering hospital-strength suction up to -300mmHg), using an improperly fitted flange can pull elastic areola tissue into the tunnel. This pinches the milk ducts and restricts flow. By sliding these ultra-soft silicone reducers directly into the M9’s standard 24mm DoubleFit™ Flange, you instantly minimize friction, center your nipples perfectly, and stimulate a faster, higher-volume letdown.
