13mm Silicone Pump Insert

A dedicated 13mm flange insert made from soft, frosted, food-grade silicone — compliant with EU food-contact regulations and fully BPA-free. Inner diameter calibrated to 13mm to refine the fit within standard 24mm flange openings. Lightweight, non-slip texture ensures stable positioning during pumping without migration or twisting. Engineered to enhance physiological pumping mechanics: the pliable silicone responds dynamically to suction cycles, supporting natural nipple elongation and reducing shear forces that contribute to cracking or blistering. Particularly effective for users reporting 'slipping', 'pinching' or 'low yield' with default flanges. Broad compatibility confirmed across UK-accessible breast pumps: Momcozy M9/M6/M5/V1 Pro/V2 Pro/S12 Pro/S9 Pro; Medela (Pump In Style, Freestyle Flex); Spectra (S1, S2, Daisy); Elvie (Stride, Curve); Willow Go; eufy Luna; Lansinoh SignaturePro; plus TSRETE, Nuliie, NCVI, Paruu, NaNaLazy and MOMMED wearables. Cleaning protocol: hand-wash with pH-neutral soap and warm water after each use; sterilise via boiling or steam at 100°C. Due to cumulative silicone fatigue and hygiene considerations, replacement every 4–6 weeks is advised for daily users — consistent with UK NICE and UNICEF Baby Friendly recommendations on accessory lifecycle management.
