13mm Breast Pump Insert

This 13mm flange insert is precision-moulded from frosted, transparent, food-grade silicone — BPA-free and tested to EU Regulation (EC) No 1935/2004 standards for materials in contact with food. Exact inner diameter: 13mm. Designed to fit inside standard 24mm flange tunnels, delivering a customised, secure fit that adapts to individual nipple anatomy and lactation phase. The ultra-soft silicone provides cushioned support during active pumping, reducing mechanical irritation and supporting consistent let-down. Its flexibility improves vacuum transmission efficiency while lowering perceived pressure — contributing to longer comfortable session durations and higher average volume per session.
